General Pumps

General Pumps is a trusted name in high-pressure cleaning industries like pressure washing, facility cleaning, and car washing. General builds extremely durable, long-lasting pumps with impressive details like anodized aluminum crankcases, oversized connecting rods, and forged brass manifolds. General has great series like their Emperor, CW, T, and Evolution that offer slightly different advantages for different applications. Learn more about each series, then figure out what you need for important specifications like pressure rating, flow rate, inlet/outlet port size, and shaft size – General Pump is sure to have exactly what you need!

Since General Pumps are high-quality, you can feel confident knowing that they will provide a long lifespan if you service and maintain your pump properly. We stock OEM parts lie O-rings, seals, valves, and packings to get your pump back to peak functionality. You can even do a full rebuild and add many years of use to maximize the value of your initial pump investment.

General Pumps for all Purposes

General Pump is known as the leader in plunger pumps for the pressure cleaning industry. They also offer a full line of pumps for other industries across the board, including car wash, hydro-excavating, mining, oil and gas, agriculture, food production and many more. They employ an in-house design team to engineer, design, and create prototypes based on the needs of their customers using requirements and the applications for which their pump will be used.

While they are best known for pressure washer plunger pumps, but General Pump offers a wide array of car wash pumps for self-service wash as well as automatic and tunnel wash, too! Car wash pumps are specifically designed to reliably and consistently handle high temperatures, high pressures, and the harsh chemicals used in the industry. These pumps typically operate within a pressure range of 100 PSI to 10,000 PSI and flow rates of 1-10 GPM depending on the model and your application.

Pumps are the heart of any car wash operation. Pumps move fluid through a system by creating a pressure difference between its inlet and outlet, causing the fluid to flow from a low-pressure area to a high-pressure area. This is achieved by using mechanical energy to displace the fluid, either through a rotating impeller, a reciprocating piston, or other mechanisms.

Maintenance Considerations for Extended Pump Life

Keep your General Pumps in the best working order with OEM replacement parts, also available when maintenance or repair time comes. Common wear parts include plungers (pistons), seals and packings, valves, valve seats, crankcase bearings, crankshafts and the pump manifold. These parts can experience wear over time due to the pump’s high-pressure operation and the nature of the fluids being pumped including abrasives and corrosives.

Regularly inspect and replace seals and packing to prevent leaks, and be sure to use clean, filtered fluids to minimize abrasive wear. Maintain proper crankcase oil levels and change oil per manufacturer recommendations. It's helpful to monitor for cavitation (e.g., air bubbles in fluid) to reduce valve and manifold damage. Follow manufacturer guidelines for replacing plungers and valves based on operating hours or performance decline.

For specific plunger pump models (e.g., General Pump brand), consult the manufacturer’s manual for a detailed list of wear parts and replacement intervals, as designs and materials vary.
