Remco 12V Diaphragm Softwash Pump 5.3GPM 100PSI - 2655

Fast, Consistent Flow from a 12V Remco Diaphragm Pump

The Remco diaphragm pump 12V is Barens' go-to pump for soft wash contractors, agricultural spraying operations, and mobile cleaning rigs that demand dependable chemical application from a battery-powered system. This 12 volt Remco diaphragm pump delivers up to 5.3 GPM at pressures up to 100 PSI, with smooth on/off control and a self-priming design that works right out of a tank, trailer, or truck bed. It runs on 12V DC, handles water, bleach, and soap mixes with chemically resistant internals, and is built around Remco's proven multi-chamber diaphragm architecture - the kind of pump that keeps working job after job instead of leaving you stranded mid-spray.

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.

Product Details: 

• 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.

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.
