Key Features
Twin vertically-opposed pistons
Delivers a given volume of oil for each full rotation of the pump shaft
Built-in one-way valves determine the flow direction
Self-sealing connections reduce oil spillage and ease installation on the pump module
Tested in one direction, determined by the Universal Dynamometer
Installed on the pump module and driven by the Universal Dynamometer, the piston pump lets students study how a reciprocating design delivers a fixed volume of oil per revolution, with its valves rather than its rotation deciding which way the oil flows.
