The ZD is a two-cylinder double-acting crankshaft driven vacuum piston pump. It primes and discharges up to 100 m³/h water, air or a water and air mixture. Thousands of movable, skid mounted, diesel engine and motor driven pumps have been supplied to the construction industry for over half a century.
Wellpoint dewatering systems lower the ground water table and enable excavations and construction under dry conditions. The pump is self priming with a suction lift (vacuum) of 9,6 m water column. The pulsating vacuum prevents well point clogging and achieves priming from greater depths.
