Triplex Reciprocating Plunger Pump

A triplex piston pump is a reciprocating positive displacement pump that uses only three pistons. This type of pump is often used for high pressure applications e.g. hydraulic systems. Due to its robust design, it is capable of pumping high viscosity fluids and fluids which contain solids.Plunger pumps have a reciprocating plunger (a type of rod). When it moves back and forth, it sucks liquid in through an inlet valve and forces it out the outlet valve. Plunger pumps have a stationary, high-pressure seal that is attached to the cylinder housing of the pump.A standard triplex pump is driven by an A.C. Motor with a crank-shaft and connecting rod assembly to convert the rotation of the motor shaft to the reciprocating motion of the pistons or plungers; the mechanics are similar to that of an internal combustion engine.
