WEL PST 100 CNP Piston Pump
The WEL PST pump is a twin cylinder, quadruple acting, crankshaft driven piston pump. Water, air or a mixture of both are primed and discharged four times per revolution. Two crankshaft driven pistons are arranged at an angle of 90 degrees to enable four piston strokes for each revolution.
The crank timing produces a moderate pulsating action in the dewatering line that prevents clogging of the wellpoint strainers and achieves priming from greater depths. Even with suction heights of several meters the pump rapidly evacuates the air from the suction pipe and starts to pump.
