VPL 04 Plunger Pump

The plunger displaces the available volume through its own volume and increases the pressure of the fluid to be pumped. The suction valve closes and the pressure valve opens the way into the process area for the pressurized fluid.Plunger pumps are pumps in which a plunger slides back and forth within a stuffing box, increasing and decreasing the working volume. Such designs are better suited for high pressures as seals are stationary within the pump, as opposed to piston designs where the seal slides within a hollow chamber.
