GP 2640034 80 Mesh SS Screen 1-1/4"/1-1/2" NPT - 7084

Protect Your Pump With the Correct Replacement Screen

The GP 2640034 is an 80-mesh stainless steel replacement filter screen built specifically for General Pump DF-series clear bowl inlet filters with 1-1/4 inch and 1-1/2 inch NPT F ports. It's a small, affordable part that does one critical job - it restores proper filtration and keeps grit, sand, rust flakes, and debris from reaching your high-pressure pump's internals. Whether you're running a pressure washing rig, an agricultural spray system, or a dedicated wash bay, a fresh mesh screen is the cheapest insurance you can buy against cavitated plungers, scored valves, and blown seals. Below, we'll walk through compatibility, benefits, how to swap the screen, and how to choose between different mesh options so you get the right filtration for your water source.

Most pressure washer inlet filters are pretty straightforward: water goes in, particles get caught, clean water feeds the pump. But the GP 2640034 is a game-changer for anyone running General Pump DF clear bowl filters on demanding jobs - you get fine enough filtration to protect expensive triplex pump components, without choking off the flow rate your pump needs to operate smoothly.

Why You'll Love the GP 2640034 Replacement Screen

A replacement screen costs a fraction of what you'd spend on new pump seals, valves, or plungers - and it can prevent all of that damage from happening in the first place. Here's what this part delivers in practical terms:

• Reliable pump protection – 80-mesh screens are standard for protecting high-pressure pumps from cavitation. The GP 2640034 traps particles before they reach your triplex pump's check valves and seals, cutting down on pitting, premature wear, and the kind of damage that sidelines rigs for days. A clogged inlet screen can starve the pump, but a missing or torn screen is far worse - it lets debris straight through.

• Cleaner water supply for consistent performance – A fresh, undamaged mesh screen stabilizes inlet flow so your pressure washer, agricultural sprayer, or fleet wash system runs smoother with fewer pressure surges and less noise. That translates to better cleaning results and less stress on every downstream component.

• Fast, low-cost maintenance – Swapping a fouled or damaged screen takes minutes. You can disassemble the polycarbonate bowl by hand, pull the old screen, drop in the new one, and assemble everything back together with no special tools required. It's genuinely that easy.

• Durable stainless steel construction – Stainless steel mesh is commonly used in water filter applications for good reason: it resists corrosion, handles repeated cleaning cycles, and holds up in outdoor, wet, and chemically exposed environments where lesser materials would rust out.

• Designed to fit specific DF filter bodies – This part is engineered to match the factory General Pump DF-series housing dimensions. Replacement screens must match the outer diameter and length of the filter housing - and the 2640034 does exactly that for the 1-1/4 inch and 1-1/2 inch port size models. That precision fit eliminates the leaks and bypass problems that happen with generic screens.

What Makes the GP 2640034 Screen Different

Generic mesh cylinders and improvised strainers might look similar, but they almost never match the exact geometry of a DF clear bowl filter housing. When the screen doesn't seat properly, unfiltered water bypasses around the edges, and your pump eats every particle your supply line delivers. That defeats the entire purpose of having a filter in the first place.

• Exact-match geometry for DF filters – The diameter, length, and end cap design of the GP 2640034 are built to seat properly inside compatible General Pump clear bowl filter bodies (DF12580 and DF15080), preventing bypass around the edges. Off-brand imports frequently miss these dimensions by just enough to cause problems.

• Optimized mesh rating – The 80-mesh count on the 2640034 is chosen to stop typical debris found in city water, tank water, and moderate well supplies without clogging as quickly as ultra-fine screens would. Mesh size refers to the number of openings per inch squared in a filter screen - and at 80 mesh, you're filtering particles under 200 microns while maintaining reasonable flow.

• Stainless mesh and support ring – The stainless steel construction resists crushing when the polycarbonate bowl is tightened and when debris loads build up against the screen face. Generic screens sometimes use thinner wire or weaker weave that deforms under normal tightening torque.

• Consistent, documented spec – Unlike off-brand imports with unknown mesh and micron ratings, GP 2640034 is manufactured to a repeatable specification. Mesh count indicates holes per inch in the screen, and General Pump maintains that standard so system designers and operators know the exact filtration level they're working with.

How the GP 2640034 Replacement Screen Works

The flow path through a DF-series clear bowl filter is simple, and that's by design - fewer complications mean fewer failure points.

1. Water enters the DF filter body – Supply water from a tank, garden hose, or plumbed line flows into the nylon body of the DF filter housing through the inlet port. This happens upstream of the pump, on the low-pressure side of your system.

2. Debris is trapped by the 2640034 mesh – As water passes through the cylindrical stainless steel screen, suspended grit, rust flakes, sand, and organic particles are caught on the outside of the mesh. 80 mesh screens filter particles down to 200 microns, stopping the kind of material that would otherwise damage valve seats, score plungers, or hold check valves open.

3. Clean water feeds the pump – Only filtered water exits the outlet side of the filter and enters your pump inlet. This delivers a more even, debris-free flow that reduces noise, surging, and internal wear.

One of the best features of the DF-series clear bowl design is that you can visually confirm how loaded the 2640034 screen is just by glancing at the transparent bowl. When the screen looks dark, coated, or unevenly loaded, it's time to pull it and clean or replace it.

Product Details: GP 2640034 Replacement Screen Specifications

Here are the key specs for easy reference and planning:

• Part number and type: GP 2640034 - OEM stainless steel mesh replacement screen for General Pump DF clear bowl inlet filters

• Material: Stainless steel mesh with stainless steel support structure, suitable for cold water and mildly warm water applications as well as common pressure washer detergent solutions

• Mesh / micron rating: 80 mesh; filters particles down to approximately 200 microns (by comparison, 50 mesh screens filter particles down to 300 microns - significantly coarser). Different mesh densities can be used depending on water source and debris size. A 200 mesh screen filters particles down to 75 microns for reference on the finer end of the scale

• Compatibility: Designed for the DF12580 (1 1/4 NPT F) and DF15080 (1-1/2 inch NPT F) clear bowl filter bodies. General Pump filters come in five port sizes: 1/2 to 1-1/2 inch - replacement screens are specific to filter body sizes, and the 2640034 is the correct match for the 1 1/4 and 1-1/2 inch group. The DF12580 has a ship weight of approximately 0.75 lbs for the complete filter assembly

• Temperature and pressure context: DF-series filters are rated for a max PSI of 150 at 70°F. The screen is designed for inlet-side, low-pressure applications - not for discharge-side high-pressure use. At higher temperatures (up to 125°F in some sizes), the pressure rating is reduced. The nylon body and polycarbonate bowl materials impose the practical temperature and chemical limits, not the stainless screen itself

• What's included: The purchase is for the stainless replacement screen only. The clear bowl, O-ring (GP part 2701078), and filter body are sold separately. General Pump filters use 50 or 80 mesh replacement screens - make sure you're ordering the mesh count you need

How to Replace a GP 2640034 Screen in Your DF Filter

Replacing the screen is a simple maintenance task that most users can handle in under five minutes. No special tools, no complicated procedures - just a basic sequence you should follow every time.

1. Shut down and depressurize – Turn off the pump or engine, release the trigger gun to bleed any residual pressure, and confirm the inlet supply line is not pressurized before touching the bowl. Safety first.

2. Remove the clear bowl – Hand-loosen the polycarbonate bowl by turning it counter-clockwise. Do not use wrenches or pliers - polycarbonate is brittle and will crack under tool pressure. The bowl is designed to disassemble by hand.

3. Pull out the old screen – Lift the existing stainless screen straight out of the housing. Inspect it for crushing, torn mesh, broken wires, or heavy fouling that won't rinse clean.

4. Rinse and inspect components – Rinse the bowl and O-ring seating area with clean water, wiping away any grit or sediment that could compromise the seal when you assemble the new screen.

5. Install the new GP 2640034 screen – Seat the new screen fully into the housing, making sure it's centered and properly aligned so water cannot bypass around it. The end cap should sit flush against the internal surfaces of the nylon body.

6. Refit the bowl and check the O-ring – Verify the O-ring is clean, supple, and correctly seated without any twists or nicks. Then hand-tighten the bowl until snug - no tools, no overtightening. A cracked bowl from overtightening is an easy mistake to avoid.

7. Test for leaks and flow – Slowly turn on the water supply and watch the clear bowl for any seepage, dripping, or air bubbles. Then start the pump and check for steady flow and normal operating sound. Any surging, cavitation noise, or visible air means something isn't sealed properly - usually the O-ring.

Choosing the Right Mesh Level for Your Application

The GP 2640034 is an 80-mesh screen, but General Pump also offers 50-mesh screens for the same DF filter bodies. Which one you need depends on your water source and how much maintenance you're willing to do.

• City water and clean tanks – For municipal supply and filtered storage tanks, a 50 mesh screen is often sufficient. A 50 mesh screen stops particles down to 300 microns, which handles most city water sediment with minimal clogging. Use a 50 mesh screen for city water applications where debris loads are light and cleaning frequency matters.

• Well water, ponds, and reclaim systems – Silty or particle-heavy sources benefit from the finer 80-mesh filtration of the 2640034. However, very dirty supplies may need staged filtration - a coarse pre-filter upstream plus the DF/2640034 combo - to prevent the screen from plugging every few hours. 80 mesh screens filter particles under 200 microns, providing significantly better protection for pump internals.

• Trade-off between protection and maintenance – Finer screens clog faster, affecting water flow. That's the fundamental trade-off: more protection from smaller particles versus more frequent cleaning. 50 mesh screens stop particles down to 300 microns with less restriction and slower buildup. 80 mesh screens catch finer material but demand more attention.

• Avoid starving the pump – An overloaded or excessively fine screen can choke inlet flow, causing pump cavitation, noise, and seal damage. Size your screen wisely, inspect it regularly, and clean it before it becomes heavily loaded. A clogged inlet screen can starve the pump - and that creates problems far more expensive than a replacement screen.

Who the GP 2640034 Replacement Screen Is For

This part is ideal for anyone running General Pump DF-series inlet filters who wants OEM-spec filtration protecting their equipment. If you've got a DF12580 or DF15080 on your rig, the 2640034 is made for you.

• Pressure washing contractors – Truck- and trailer-mounted rigs using DF clear bowl filters to protect triplex pumps on residential driveways, commercial building exteriors, and large flatwork. The GP 2640034 is designed for 1-1/4" water filters used in pressure washers - exactly the size range most professional rigs run.

• Facilities and fleet managers – Wash bays and equipment-cleaning stations where pumps see daily use and a clean inlet screen prevents costly downtime. Keeping a spare 2640034 on the shelf means you can swap screens in minutes instead of waiting on a parts order.

• Agricultural and ranch operations – Upstream of pumps used to clean tractors, sprayers, barns, and pens that often draw water from tanks or non-potable sources where debris and sediment are a constant concern.

• DIY power users with General Pump filters – Serious home users and small shops running DF filters who want OEM-spec filtration instead of guessing with generic mesh cylinders that may not match their housing.

Keeping Your GP 2640034 Screen Performing for Years

Good habits around inspection, cleaning, and storage will greatly extend the life of both the screen and your pump.

• Regular visual checks – Glance at the clear bowl before each use. If the screen looks dark, coated, or unevenly loaded with debris, pull it and clean it before starting the pump. The transparent DF bowl makes this dead simple.

• Cleaning technique – Rinse from the inside out with clean water to push trapped particles off the mesh surface. Use a soft brush only if needed. Avoid sharp tools, picks, or wire brushes that could tear or deform the stainless mesh. Clean the screen monthly for clean city water. Inspect the screen weekly for buildup on tank water.

• Replacement interval – Replace the screen when you see signs of corrosion, broken wires, crushing, or when it no longer rinses clean quickly - even if it hasn't outright failed. A partially damaged screen can let particles through at the weak points while restricting flow everywhere else.

• Protect from chemicals and heat – While the stainless steel screen itself is robust, the compatibility and temperature limits of the overall filter are determined by the DF housing materials. The nylon body and polycarbonate bowl can degrade with harsh solvents, strong acids, or chlorinated bleach. Keep inlet temperatures within the DF filter's published range (generally 70–125°F depending on size and configuration).

• Off-season storage – Flush the bowl and screen with clean water, let everything dry, and store the assembly away from direct sunlight and corrosive atmospheres. UV exposure degrades polycarbonate over time, and standing water in the bowl can promote mineral buildup on the mesh.

Frequently Asked Questions About the GP 2640034 Replacement Screen

Here are the fitment, use, and maintenance questions that come up most often when ordering this replacement screen.

How do I confirm that GP 2640034 fits my filter? Check the model number stamped on your General Pump DF clear bowl filter body. The 2640034 is the OEM 80-mesh screen for the DF12580 (1 1/4 NPT F) and DF15080 (1-1/2 inch port size) models. General Pump filters come in five port sizes from 1/2 to 1-1/2 inch, and each size group uses a different screen. The 2640034 only fits the 1 1/4 and 1-1/2 inch bodies - screens sized for the 1/2, 3/4, or 1-inch housings are different part numbers.

Is the 2640034 screen easy to install? Yes. It's designed as a direct slip-in replacement. You can disassemble the bowl by hand, swap the screen, and assemble everything back together in a few minutes as long as the system is depressurized. No tools needed.

How often should I clean or replace the screen? Clean the screen monthly for clean city water supplies. Inspect the screen weekly for buildup on tank water, well water, or reclaim systems. Replace the screen when the mesh shows damage, heavy staining that won't rinse out, or broken wires - don't wait for a complete failure.

Can I use this screen with hot water? The stainless steel screen itself tolerates warm water without issue. However, the DF filter's polycarbonate bowl and EPDM O-ring are the limiting factors. DF-series filters are generally rated for max PSI of 150 at 70°F, with reduced ratings at higher temperatures (up to about 125°F in some configurations). Always mount DF filters on the cool inlet side of the pump, never on the discharge side.

What if my clear bowl is leaking or pulling in air after installing the new screen? Leaks and air draw are almost always caused by a worn, dirty, or mis-seated O-ring - not the screen itself. Remove the bowl, inspect the O-ring for nicks, flattening, or debris, clean the seating surface, and reinstall. If the O-ring is damaged, replace it (GP part 2701078). Avoid overtightening the bowl, which can crack the polycarbonate and make the problem worse.
