Water Displacement Unit
 Three Water Cylinders with dual-acting pistons
 Feed Water Valves and Energy Recovery Valves
on all cylinders
Hydraulic Power Unit
 Highly Efficient Hydraulic pumps provide the
energy to power the Water Displacement Unit
 Hydraulic Cylinders transfer the energy from the
Hydraulic Pumps to the dual-acting pistons
Electronic Control Unit
 Sophisticated Solid State control system syn-
chronizes positioning of the dual-acting pistons
and ensures all valves open and close at near
zero flow
 Control System is designed to provide long last-
ing, stable control delivering a steady flow and
pressure output from the Water Displacement
