TOKIMEC P16VM P21VM P21 P31V P40V P70V P100V P130V Series P31VR-20-EP-D-C7-21-S245-J Variable Displacement Piston Pumps

The piston pump of TOKYO GAUGE is a reciprocating pump, belonging to a positive displacement pump. The plunger is driven by the eccentric rotation of the pump shaft, and reciprocates. Both the suction valve and the discharge valve are one-way valves. When the plunger is pulled out, the pressure in the working chamber decreases and the outlet valve is closed. When the inlet pressure decreases, the inlet valve is opened and liquid enters; When the plunger is pushed, the pressure in the working chamber increases and the inlet valve is closed, higher than the outlet pressure. The outlet valve is opened and the liquid is discharged.
