Whether you're a contractor running a trailer-mounted rig or maintaining a permanent wash bay, the TS1711 is designed for the kind of daily, multi-hour use that separates professional-grade equipment from consumer-level alternatives.

If you need a proven, serviceable pressure washer pump that balances moderate flow and strong pressure output for demanding work, the TS1711 is built to be that pump.

Built to Deliver Reliable Power and Performance

The TS1711 earns its place on professional machines by delivering consistent pressure and flow shift after shift, with fewer unplanned stops and lower long-term cost of ownership.

• Consistent cleaning power – At 3.5 GPM and 2,700 PSI, the TS1711 provides strong, even pressure suited for concrete restoration, fleet vehicle cleaning, property maintenance, and equipment degreasing. That combination of flow and pressure handles a wide range of commercial tasks without requiring constant nozzle changes or system adjustments.

• Designed for daily professional use – The pump requires a minimum of 6.5 EBHP for operation, making it a natural fit for mid-range gas engines and electric motors commonly used in the pressure cleaning industry. It's built for contractors who need their equipment running reliably several hours per day.

• Durable construction – The TS1711 features a forged brass manifold for corrosion resistance, solid ceramic plungers for wear resistance, and a high-capacity anodized aluminum oil-bath crankcase that keeps internal components cool under extended operation. These materials handle demanding environments - water, detergents, temperature swings - without premature degradation.

• Smooth, low-RPM operation – Running at 1,450 RPM, the TS1711 generates less heat, vibration, and noise compared to higher-speed pumps. This lower operating speed reduces component stress and extends service intervals when the drive system is properly matched.

• Serviceable and supported – General Pump TS1711 has multiple repair kits available, covering valves, packings, oil seals, and more. This makes the pump economical to maintain and rebuild rather than replace, keeping total ownership costs down over time.

What Sets the General Pump TS1711 Apart

Many replacement and aftermarket pumps look similar on a spec sheet. Where the TS1711 separates itself is in construction quality, standardization, and the depth of its parts ecosystem.

• 47 Series industrial frame – The TS1711 is part of General Pump's Series 47 lineup, a frame size that has become a standard in the pressure cleaning industry. Customers who choose this platform benefit from proven reliability and broad compatibility across multiple machine brands.

• 24 mm solid shaft configuration – The 24 mm solid shaft delivers superior torque transfer and durability under load compared to smaller or hollow shafts. This shaft size is widely compatible with belt-drive and gear-drive setups, making installation and replacement straightforward.

• Proven brass manifold design – The forged brass manifold resists corrosion from water minerals, detergents, and thermal cycling - a significant advantage over pumps using cast iron or plated steel manifolds that corrode faster in real-world conditions.

• Ceramic plunger longevity – The pump uses solid ceramic plungers that are lubricated continuously. Ceramic resists scoring and surface degradation far longer than metal plungers, which directly extends seal life and reduces the frequency of packing service.

• Wide ecosystem of parts – Because the TS1711 shares its frame and many internal components with other 47 Series models, stocking parts is simpler. Valve kits, packing kits, and seal kits are readily available, and service procedures are consistent across the series.

How the TS1711 Works in Your Pressure Washer System

A triplex plunger pump is the heart of any professional pressure washer. It converts rotational energy from an engine or motor into high-pressure water output. Here's the way the TS1711 fits into that system:

1. Power input – The pump connects via its 24 mm solid shaft to a gas engine or electric motor. This connection is typically made through a belt-and-pulley arrangement or a gearbox, configured to deliver the rated 1,450 RPM to the pump shaft under load.

2. Water intake – Water is drawn from a supply hose or tank through the inlet port (½-14 BSPP female). Proper filtration and short, adequately sized inlet plumbing prevent cavitation and protect the stainless steel inlet valves from debris damage.

3. Pressure generation – Three solid ceramic plungers reciprocate inside the manifold, compressing water on each stroke. This triplex design produces smoother flow with less pulsation than single- or dual-piston pumps, building operating pressure up to 2,700 PSI.

4. Controlled output – Pressurized water exits through the discharge port (3⁄8-19 BSPP female), passes through an unloader or pressure regulator valve, then travels through the high-pressure hose to the spray gun and nozzle.

5. System protection – An unloader valve, relief valve, and properly plumbed bypass line protect the TS1711 from pressure spikes and overheating during bypass or when the trigger is released. These accessories are essential to safe, long-lasting operation.

Installation Considerations for the TS1711

Correct installation directly impacts how well the TS1711 performs and how long it lasts. Cutting corners during setup leads to premature wear, cavitation, or alignment failures.

• Mounting orientation – Secure the pump to a rigid base or frame using the factory mounting points. Ensure the crankcase sits level for proper oil distribution. Allow adequate clearance around inlet and discharge ports for plumbing connections and future service access.

• Drive configuration – Pair the 24 mm shaft with appropriately sized pulleys and belts (or a gear reducer) to deliver exactly 1,450 RPM at the pump under load. Overspeeding causes excessive wear and heat; underspeeding reduces flow and efficiency. Always verify RPM with a tachometer under actual operating conditions, not just at idle.

• Inlet plumbing – Use a short, oversized inlet hose to minimize friction losses. Install a quality inlet filter to protect valves from debris. Eliminate any air leaks in the suction line and ensure the water supply meets the pump's needs - the maximum inlet pressure is 125 PSI, and suction lift should not exceed 9 ft.

• Discharge plumbing – Size the discharge hose for the full 2,700 PSI working pressure. Include an unloader/pressure regulator and, where applicable, a pressure gauge. All fittings must be rated for the system's maximum pressure.

• Initial start-up – Fill the crankcase with the recommended oil (General Pump Series 100 or equivalent) to the proper level. Prime the pump with water before starting the engine or motor. Check all connections for leaks and bring the system up to full pressure gradually.

Maintenance and Service for the General Pump TS1711

Regular maintenance is the single most effective way to extend the life of your TS1711 and keep cleaning performance consistent over thousands of hours.

• Routine checks – Before each use, verify oil level and color through the sight glass. Inspect the inlet filter, check for water leaks around the manifold and crankcase, and listen for unusual noise or vibration during operation.

• Oil changes – Change the oil after the first 50 hours of operation, then at approximately every 500 hours or per manufacturer guidelines. Use the recommended pump oil - never substitute with engine oil or gear lubricant. Dirty or degraded oil accelerates bearing and crankcase wear.

• Packing and seal service – Water leaking between the manifold and crankcase, or a gradual drop in pressure, signals worn packings. Dedicated TS1711 packing kits allow you to replace all sealing components and restore full performance.

• Valve inspection – Pulsation at the spray gun, inconsistent pressure, or sudden drops in output often point to worn or fouled valves. Repair Kit 1 includes a valve assembly for the TS1711. Repair Kit 28 requires three units to service the entire pump, covering all inlet and discharge valves across the three cylinders.

• Using TS1711 repair kits – Additional kits cover specialized components: Repair Kit 2 is for piston guide oil, and Repair Kit 3 contains a crankshaft oil seal. Having these kits on hand minimizes downtime and ensures you can address any service need quickly.

• Storage and winterization – When the pump will be out of service, flush it thoroughly with clean water, drain all residual water, and add antifreeze or a corrosion inhibitor. Store the pump above freezing to prevent damage to ceramic plungers, brass components, and seals.

Where the TS1711 Fits Best: Ideal Applications

Choosing the right pump starts with matching it to your actual work. Here's where the TS1711 excels:

• Commercial pressure washing contractors – Building exteriors, sidewalks, parking structures, and fleet vehicles. The 3.5 GPM / 2,700 PSI output covers the most common contract cleaning tasks.

• Facility and property maintenance teams – Schools, warehouses, municipal buildings, and industrial plants benefit from a pump that runs reliably day after day with minimal supervision.

• Agricultural and farm operations – The TS1711 can be utilized for cleaning vehicles and heavy equipment, as well as barns, milking parlors, and tractors. The pump is adaptable for agricultural cleaning and sanitation applications where moderate pressure and continuous-duty reliability are essential.

• Light industrial washing systems – Fixed wash bays or semi-permanent installations that operate several hours daily. It is designed for industrial cleaning tasks requiring durability and consistent output over long runs.

• When the TS1711 is not ideal – If your application demands very high PSI (3,500+) with high flow (5+ GPM), or involves fluid temperatures well above 165°F, or requires ultra-high-volume throughput, consider stepping up to a larger 47 Series model or General Pump's KE Series.

Frequently Asked Questions About the General Pump TS1711

These questions address the most common selection, compatibility, and service topics customers ask about the TS1711.

Is the TS1711 compatible with my existing pressure washer? Check your current pump's frame size, shaft diameter, mounting bolt pattern, and required flow/pressure. The TS1711 uses a 24 mm solid shaft and 47 Series frame, which matches many belt-drive and gear-drive commercial machines. Confirm inlet and discharge thread sizes (½-14 BSPP and 3⁄8-19 BSPP) before ordering.

What size engine or motor do I need to drive the TS1711? The pump requires a minimum of 6.5 EBHP at the shaft. For gas engines, this typically means a rated engine output of 7–9 HP or more, depending on drivetrain losses. Always verify with your engine or motor manufacturer to ensure sufficient power delivery at 1,450 RPM under load.

Can I run hot water through the TS1711? Yes. The maximum fluid temperature for the TS1711 is 165°F, so it is suitable for both hot-water and cold-water washing systems within that range. Do not exceed this limit, as higher temperatures will damage seals and ceramic components.

How often should I service the seals and valves? Service intervals depend on operating conditions. Under typical commercial use, review packings and valves every 500–1,000 hours, adjusting downward for continuous-duty, high-heat, or dirty-water applications. Any change in pressure stability or visible leaking should prompt immediate inspection.

What repair kits are available for the TS1711? Multiple kits are available: valve assembly kits, packing kits, piston guide oil kits, and crankshaft oil seal kits. Some assemblies - such as valves - require multiple kits (Repair Kit 28 requires three units) to fully service all cylinders. Review your pump's service manual for the correct part numbers.

What should I do if my TS1711 loses pressure or starts pulsing? Start by checking the inlet supply: confirm adequate water flow, clean filter, and no air leaks. Next, inspect the unloader valve and nozzle for blockages or wear. If the issue persists, open the manifold and inspect valves and packings for scoring, debris, or wear - and replace using the appropriate TS1711 repair kit.
