Pump Flow Diagram

Jet pumps are mounted above the well either in the home or in a well house and draw the water up from the well through suction see single drop jet pump system diagram on next page.

Pump flow diagram. Common loop with one flow center per unit multiple units on common loop field parallel pumping arrangement two units with one flow center heat pump flow controller field supplied full port ball valve each heat pump must include p t. Hydrostatic pumps are positive displacement pumps while hydrodynamic pumps can be fixed displacement pumps in which the displacement flow through the pump per rotation of the pump cannot be adjusted or variable displacement pumps which have a more complicated construction that allows the displacement to be adjusted hydraulic pump. A mechanical or electrical drive is typically connected to a pump that is used to compress the medium. Flow center flow for balancing heat pump to ground loop figure 5.

The directional control valve with built in relief features optional flow control to control the speed of the winch. For every pressure the pump will only deliver one specific flow rate. The diagram shows a winch powered by a hydraulic motor. The output pressure of the pump is set using a back pressure regulator.

Therefore to control the flow of a centrifugal pump simply set the output pressure to the point on the p v diagram that allows the pump to deliver the desired flow rate. The hydraulic pump and motor must be matched to the torque requirements of the winch.
