Pressure Washer Pumps
What makes a pressure washer better than another one? Is it the motor that powers the machine? Is it the pressure hose and spray ends that complete the job for you? In reality, what makes the difference are the pressure washer pumps.
The motor powers the pump, but the pump delivers the water through the pressure hose, trigger and spray nozzle. Some of the best pump manufacturers include General, AR, Cat, Comet, Hypro, Mi-T-M, and Giant. Motors, whether electric or gas will last the longest on most pressure washers. Due to the pressures involved on some of the higher rated (3000 to 4000 PSI) models, pumps tend to wear out over time.
If your cleaning business depends on your pressure washers being online at all times, a failed pressure washer pump can destroy your schedule. Being able to replace pressure washer pumps in a short period of down time is essential to your business profitability. You can also upgrade your pressure washer by increasing the flow rate your pressure washer pumps can put out. Pressure rating and flow rate are the two main factors with prices on pressure washer pumps.
Comet makes pumps for just about any kind of pressure washer – electric, gas, with stainless steel pistons, aluminum manifolds, gear reducers and built in unloaders. All of them are in the 1.9 gallon per minute to 5.9 gallon per minute range for flow rate and have pressure ratings as high as 4000 PSI. Revolutions per minute go from 1450 to a maximum of 3400. Prices on Comet pumps start near two hundred dollars ($200) and top out at around six hundred dollars ($600).
General is one of the largest makers of pressure washer pumps. They have one model that has an amazing flow rate of forty one gpm at 1200 PSI and one that tops out at 5800 PSI. Both are over two thousand dollars ($2000).
