Plumbed Pump-AR Pump-4GPM-3500-4000PSI-1 Inch-Horizontal Shaft
MANIFOLD
New high efficiency design concept. (Patented). Forged brass for strength and no porposity for long life and higher hydrostatic pressures.

BEARINGS
Over-sized for maximum life and load disbursement, needle bearing on the drive side and ball on the non-drive side. Each bearing is held in position on the crankshaft and crankcase by snap rings. This assures positive alignment and centering of the connecting rods and crankshaft in relation to the crankcase, it also eliminates the crankshaft from floating.

Tips:

Please make sure to have a inlet filter in place when plumbing up new pumps. This picture is from a brand new installation that they didn't install a filter. Please note all the debris plugging the check valve.

Cavitation:

 Pressure washer Pumps


Cavitation:

 Proper design of the pump inlet supply is critical to the success of any pumping system. The supply can be gravity, suction or pressure fed depending on the pump selected. Improper supply to the pump will cause cavitation. Cavitation is the formation and collapse of gaseous pockets 
(cavities) in a liquid.
Cavitation occurs when a lack of liquid to the inlet causes vaporization in the low pressure chamber of the pump.
When a vapor bubble is re-pressurized it quickly collapses supersonically and the shock wave erodes the surface it is on. Causes pitting and erosion of metallic or ceramic components. 

Cavitation will decrease pump outlet flow and pressure as well because the pump doesn’t fully prime with liquid.  Instead, the pump is attempting to pump a combination of liquid and vapor.  Cavitation will cause shorter seal life, pitted valves, and manifolds.  The short seal life is caused by the lack of lubrication (water is a lubricant in this scenario) increasing wear.
