An education on replacement pressure washer pumps. ETS Bolt-N-Go Pump Packages are a great choice for replacing that worn out pump. Why put $300-$1,000 of parts & labor into fixing a pump when you can remove your old pump and Bolt-on a brand new one? All you need is a gas engine and a straight shaft (where your pump connects to the engine).
Don't compare pumps just on price! We have listed the list prices on the repair parts to completely rebuild your pump (this includes pistons/plungers, check valves and water seals) should it stop working, leak water or lose pressure. Keep in mind the average bolt-on unloader costs between $80-120. The pumps that have unloaders built into their manifold (pump head) require replacement parts that typically run $60-80

How to Choose the Right Replacement Pressure Washer PumpChoosing a replacement pressure washer pump involves more than matching the price. The pump must be compatible with your engine, drive system, and cleaning requirements. Check the engine horsepower and shaft size. Confirm the engine's horsepower, shaft diameter, shaft configuration, and mounting requirements before ordering. Match the PSI rating. Your replacement pump must be rated for the working pressure your pressure washer requires. Never exceed the ratings of your equipment. Compare GPM water flow. Gallons per minute determine how much water the pump delivers. Choose a compatible pump that meets your cleaning needs. Verify RPM and drive compatibility. Check the pump's rated operating speed and whether it is designed for your direct-drive or other drive configuration. Consider replacement versus rebuilding. If your pump has worn seals, damaged valves, or leaking components, compare the cost of the correct repair parts with the cost of replacing the complete pump.
Why Consider a Bolt-N-Go Replacement Pump?A compatible replacement pump package can be a practical alternative to rebuilding a worn-out pump. Before purchasing, verify the mounting configuration, shaft dimensions, operating specifications, and included components. Compare the complete replacement cost with the parts and labor needed to repair your existing pump. Need Help Finding a Compatible Pump?Not sure which replacement pressure washer pump fits your engine? Contact ShopETSonline at 610-583-7657 for assistance identifying a suitable pump. Having your engine model, shaft measurements, current pump model, PSI, and GPM available can help narrow down the options.
