I'll run through the basic 

Benefits of a Fixed-Displacement Hydraulic PumpUnlike fixed-displacement pumps, variable displacement pumps are able to increase or decrease the fluid flow rates electronically, manually, or hydraulically.

Variable-Speed Pump Drives Save Energy, Cut Noise and HeatMar 5, 2018 — “Using a variable-displacement piston pump makes it possible to adjust pressure, pump displacement, and motor speed (torque and speed) to Definition of pumps-All types of pumps definitions-Advantages Oct 7, 2020 — Variable displacement pump can produce variable flow and pressure and can be changed by the operator. And these pumps are energy efficient.

What is the difference between fixed and variable pumps?May 9, 2019 — On opposing sides of the swashplate sits a bias piston (and spring) and a control piston. A variable displacement piston pump is designed to be Hydraulic Pumps: Fixed vs. Variable DisplacementSep 20, 2013 — Simple, fixed-displacement pumps are perfect for single jobs that need to be repeated indefinitely over long periods of time; variable- 

Choosing the right hydraulic pumpThe main advantage of being able to vary the displacement of a pump is to save energy when the circuit does not require the pump's maximum power. Piston and Understanding Variable Displacement Pumps - WHYPSMay 4, 2019 — These pumps don't require manual control. The valves that control the speed of the actuators will control the fluid flow rate. So, variable
