Basic Hydraulic Principles > Hydraulic Swash Plate Pump
A constant displacement hydraulic pump uses a fixed swash plate to drive a set of pistons in and out as they revolve.
At the top of their stroke, the pistons move over the inlet port and draw in fluid at low pressure. The fluid is then carried round and expelled through the outlet port at high pressure as the swash plate drives the piston into the cylinder.
To demonstrate the operation of a hydraulic pump to students in the classroom, Sphaera's interactive hydraulic swash plate pump features 8 revolving cylinders that draw and expel hydraulic fluid. As they do so the change in pressure is clearly visible as the fluid changes colour.
Operation can be viewed at fast or slow speed and from the side or above. A very useful feature is the ability to view the operation of a single cylinder as it travels through its cycle, drawing in fluid at low pressure and then compressing the fluid to expel it at high pressure.
