High Pressure Pumps

Pumpbiz offers a comprehensive range of high-pressure water pumps for various applications. Our inventory features top manufacturers and includes both engine-driven and electric motor-driven pumps, available in centrifugal and diaphragm models. If you are not sure which pump is best, please give us a call. While we are always happy to sell pumps to you, we want to be sure it is the right pump for your needs.

Engine-Driven & Electric Pumps for a Range of Applications

Our inventory includes both engine-driven and electric pumps for high-pressure applications.

Electric water pumps are very common in most applications. From high-pressure pumps for irrigation to small pumps for ice machines, electric motors provide the primary power. If you have a relatively stationary need with reliable electric power, high-pressure electric pumps are your best choice.

Gorman-Rupp and AMT are among the most popular brands for engine-driven high-pressure pumps. Their gas or diesel-powered pump engines provide portable and reliable high-pressure pumping capabilities. We also provide LP conversion kits for high-pressure fire pumps.
