• Primary benefit: A 12V Remco diaphragm pump is designed for reliable fluid transfer of soft wash chemicals and spray solutions from a compact, battery-powered package - no generator, no gas engine, no hassle.

Why You'll Love a Remco 12V Diaphragm Pump on Your Rig

Specs are nice, but what matters is what this pump actually does for you on the job site. Here's what real-world operators notice when they put a Remco 12V diaphragm pump to work.

• Soft wash ready out of the box – Softwash systems use low pressure of 100 PSI, and this pump is built exactly for that range. You can apply sodium hypochlorite, surfactant, and water mixes to roofs, siding, fences, and building exteriors without causing damage to delicate surfaces. Softwashing effectively kills algae, mold, and mildew at the source, and this pump makes the whole process easy - no ladder gymnastics, no surface gouging, no callbacks.

• Mobile and quiet 12 volt operation – These pumps are powered by 12V DC sources allowing mobile use on trailers, trucks, UTVs, and van-mounted rigs. Compared to gas-powered pumps, a Remco 12V diaphragm pump runs significantly quieter - a great advantage when you're working residential neighborhoods, HOA communities, or noise-sensitive facilities. Just wire it to your battery and go.

• Self-priming and dry-run tolerant – Self-priming height can reach up to 14 feet, so you can pull chemical mix from a tank mounted below the pump without manual priming. Remco diaphragm pumps can run dry without immediate damage, giving you better peace of mind than centrifugal or impeller-style pumps that seize up the moment they lose prime.

• Smooth, consistent flow – The multi-chamber diaphragm design and built-in pressure switch work together to maintain steady flow to your soft wash gun or spray wand. The diaphragm design reduces shear on fluids, minimizing leaks and delivering predictable output whether you're working a short wand or a 150-foot hose run.

• Low maintenance and field-serviceable – Replaceable diaphragms, valves, and check assemblies mean you can keep this pump running season after season without buying a whole new unit. Plan on swapping valve kits annually in heavy chemical service, and the pump rewards you with years of reliable operation.

What Makes a Barens + Remco 12V Diaphragm Pump Different

Most generic 12V sprayer pumps you find online are built with inconsistent output, short life spans, and poor chemical compatibility. They use cheap elastomers that swell and crack after a few weeks of bleach exposure, open motors that corrode in mist, and pressure switches that fail after a few hundred cycles. A Remco diaphragm pump sourced through Barens is a completely different category of equipment.

• Matched for real soft wash and spray work – Barens selects Remco 12V diaphragm pump models with flow and pressure ranges tailored specifically to soft wash, roof cleaning, and agricultural spot spraying. A typical softwash system operates at 5.3 GPM, and these pumps deliver exactly that - not some vague "up to" number printed on a box that never materializes at the nozzle. Typical flow rates range from 0.5 GPM to 7.0 GPM across the Remco lineup, so there's a model for every job scale.

• Chemically resistant wetted parts – Pumps feature chemical-resistant components such as Viton valves and Santoprene diaphragms, housed in polypropylene bodies. These materials are specifically chosen to handle the sodium hypochlorite and detergent mixes used daily in exterior cleaning. Generic pumps with EPDM or Buna-N seals simply can't survive in the same environment.

• Built around system integration – Barens configures these Remco pumps with practical port sizes, wiring leads, and mounting patterns that drop easily into skids, trailer rigs, or aluminum base plates. You won't be hunting for oddball adapters or re-engineering your plumbing to make things fit.

• Backed by Barens product support – When you purchase through Barens, you get product knowledge, stocking of spare diaphragms, valves, strainers, and support for troubleshooting flow, priming, and wiring issues. That's the difference between buying a brand you can rely on and rolling the dice on an anonymous import.

How a Remco 12V Diaphragm Pump Works in Your System

A Remco 12V diaphragm pump is a positive-displacement pump: it pulls liquid in through inlet valves and pushes it out through outlet valves at controlled pressure. The flexible diaphragm stretches downward to create suction, then flexes upward to force fluid out - constant repetition yields smooth, reliable flow. Here's how it works in a real spray system.

1. Power and plumbing: Connect the pump to a 12 volt deep-cycle battery or vehicle electrical system, wiring through a properly sized fuse and switch. Run your suction line from the chemical mix tank to the pump inlet, and your discharge line from the pump outlet to your hose reel, spray wand, or soft wash gun. Use adequately sized suction hose and keep runs short to maximize self-priming performance.

2. Prime and start: Fill the suction line, open the gun or trigger, and let the self-priming action pull chemical mix from the tank. 12V diaphragm pumps are self-priming up to 8 feet with standard setups, and up to 14 feet in optimized configurations. The internal pressure switch controls start and stop based on trigger position - no manual intervention required.

3. Spray and control: Squeeze the trigger and the pump starts automatically. Pressure builds to your working range - softwash systems use low pressure of 100 PSI, and these pumps are designed to deliver exactly that. They offer advanced flow control options to manage pressure and flow rates smoothly. Release the trigger, and the pressure switch shuts the pump down to protect components and conserve battery life.

4. Flush and protect: After using bleach mixes, flush the entire system with clean water. Run one to two full tanks of fresh water through the pump at the end of each workday. Never leave sodium hypochlorite sitting in the pump overnight. This single habit dramatically extends diaphragm and valve life.

Product Details: Key Specs for a 12V Remco Diaphragm Pump

Exact numbers may vary by specific Remco model, but here are the key specs for a representative 5.3 GPM, 12V soft wash pump - the sweet spot for most single-operator and small crew rigs.

• Flow and pressure: 12V diaphragm pumps can deliver 5.3 GPM flow rate at open flow, with shutoff pressure factory set at 100 PSI. Flow at 100 PSI shutoff is approximately 1.55 GPM. 12V Remco pumps can generate pressure of 60 to 150 PSI depending on the model - the EF5500-BOX pump operates at 60 PSI pressure, while higher-output models reach 100 PSI for full soft wash capability. These pumps are designed for agricultural spraying and chemical transfer as well as exterior cleaning.

• Voltage and current draw: 12V DC operation within an 11.5–14.5 V input range. Current draw runs approximately 8.5 A at open flow and up to 19 A at 100 PSI shutoff. A 25 A fuse is recommended. Size your wiring, fuse, and battery accordingly - undersized wiring causes voltage drop, motor heating, and premature failure.

• Materials: Polypropylene housing, Santoprene diaphragm, Viton (FKM) valves. These pumps are chemical and corrosion resistant, engineered to survive daily contact with sodium hypochlorite mixes at concentrations up to 12–12.5%.

• Port sizes and connections: Standard ¾-inch quick-attach female inlet and outlet; some variants offer ½-inch FNPT ports. Compatible with common soft wash hose sizes and standard plumbing fittings.

• Mounting and dimensions: Remco pumps are compact and energy-efficient, enabling portable operations. The footprint is small enough to mount on skids, trailers, and aluminum base plates without crowding other components. Mounting feet are integrated into the pump housing.

• Duty cycle and protection: Intermittent duty cycle with recommended cooling periods - typically 45–50 minutes of operation followed by 15 minutes of cool-down to protect the motor and elastomers. Built-in pressure switch handles automatic start/stop. Maximum fluid temperature is 140°F (60°C). Sealed IP65-rated motor resists mist, salt, and chemical aerosol.

• What comes in the box: Complete 12V Remco diaphragm pump assembly with integrated mounting feet, wiring pigtails, and basic documentation. Battery, hoses, guns, reels, and accessories are sold separately.

Getting the Most from Your Remco 12V Diaphragm Pump

Proper selection, installation, and care are what separate a pump that lasts one season from one that runs for years. Here's how to get the most from your investment.

• Choosing the right flow and nozzle size – Match the GPM rating to your typical job size and choose appropriate orifice sizes at the gun or nozzle. Oversized nozzles starve the pump of back-pressure; undersized nozzles overload it. For most soft wash work, a 5.3 GPM pump paired with a properly sized soft wash nozzle hits the sweet spot.

• Power supply and wiring best practices – Use a true deep-cycle battery with sufficient amp-hour capacity. For a pump drawing up to 19 A, that means a Group 27 or larger battery for full-day use. We recommend using 14-AWG or heavier wire for the run length, installing a correctly sized fuse (25 A for most models) near the battery terminal, and using corrosion-resistant terminals throughout.

• Inlet plumbing and filtration – Use an adequately sized suction hose - ¾-inch minimum - and keep runs as short as possible. Install a 50-mesh inline strainer to protect diaphragms and valves from debris. Minimize restrictions and eliminate air leaks in the suction line to get the best self-priming performance.

• Flushing after bleach use – After every workday using sodium hypochlorite mixes, flush the pump and lines with one to two full tanks of clean water. Never leave bleach standing in the pump overnight. This single practice does more for pump longevity than any other maintenance step.

• Routine inspection and maintenance – Check for leaks, unusual noise, or pressure loss before each use. Plan on replacing valve and diaphragm kits annually under regular chemical service. Keep spare kits on hand so a worn valve doesn't shut down your whole operation.

• Off-season storage – Run a pump-safe antifreeze or storage solution through the entire system before winter. Drain all lines and store the pump in a dry, protected area to prevent freeze damage. Cover exposed ports to keep insects and debris out.

Frequently Asked Questions about Remco 12V Diaphragm Pumps

These are the most common questions buyers ask before choosing a 12V Remco diaphragm pump from Barens.

Can a 12V Remco diaphragm pump handle bleach for soft washing? Yes. Remco pumps are used in softwash systems for cleaning and are built with Viton valves and Santoprene diaphragms specifically to handle sodium hypochlorite at concentrations up to 12–12.5%. Actual component life depends on concentration, temperature, and how consistently you flush after each use.

What size battery do I need? We recommend a Group 27 or larger deep-cycle 12V battery for full-day use. The pump draws approximately 8.5 A at open flow and up to 19 A at pressure, so for a typical workday you'll want 80–200 Ah of capacity depending on how continuously the pump runs. Some operators double batteries for extended jobs.

Is the pump truly self-priming? Yes. 12V diaphragm pumps are self-priming up to 8 feet in standard configurations, and optimized setups can reach up to 14 feet of suction lift. Performance is best with short, properly sized suction lines and no air leaks at fittings or connections.

Can I run this pump dry? Remco diaphragm pumps can run dry without immediate damage, which is a significant advantage over many centrifugal and impeller pumps. However, intentional or extended dry-running will still shorten diaphragm and valve life. Treat dry-run tolerance as a safety net, not an operating mode.

How does it compare to gas-powered pumps for soft wash? A 12V Remco diaphragm pump is simpler, quieter, and far easier to mount in compact rigs than gas-powered alternatives. For single-operator and small crew soft wash work, the 12 volt system works beautifully. Gas systems may still make sense for very high-flow, multi-gun setups where you need 10+ GPM - but for the vast majority of exterior cleaning contractors, the Remco 12V is the better fit. You can review videos from working contractors to see these pumps in action on real job sites.

Where do I get replacement parts? Barens supplies diaphragms, valves, strainers, hoses, guns, and related accessories to keep your Remco 12V diaphragm pump operating over the long term. Having a reliable parts source is part of the security of choosing a proven brand over a disposable no-name pump.
