Double-Action Piston Pump Cutaway

Piston pumps are positive displacement pumps that move and pressurize fluid by using the force of a reciprocating piston moving in an enclosed cylinder. The piston draws fluid into the cylinder and pushes it out under pressure as the volume in the cylinder gets progressively larger and then smaller as the piston reciprocates.

These versatile pumps have a wide variety of commercial and industrial applications, such as: hydraulic pumps to power heavy machinery; commercial car washes; water irrigation or delivery systems; pressure cleaning equipment; small machines like paint sprayers; reverse osmosis systems; oil production; chemical processing; and multiple other uses within the aerospace, marine, agriculture, and automobile industries.

Double-action piston pumps are reciprocating devices that discharge fluid on both the forward and backward (or up and down) strokes of the piston, providing a continuous, high-efficiency flow. They features a cylinder divided into two chambers with four check valves, allowing them to suction and discharge simultaneously. These pumps are commonly used for high-viscosity oil transfer, hydraulic power, and air pumping.

DAC Worldwide’s Double-Action Piston Pump Cutaway (278-133) is a sample industrial double-action piston pump that has been carefully sectioned and color-coded to train learners in the design, operation, construction, and maintenance of this common process pump used throughout industry. The cutaway exposes and showcases the complete internal configuration of an industrial double-action piston pump. Moreover, seal features, bearings, and hardware locations have been retained to allow realistic, hands-on pump maintenance and operation training.
