It functions as a hydraulic transformer that takes in water at one "hydraulic head" (pressure) and flow-rate, and outputs water at a higher hydraulic-head and lower flow-rate. The device utilizes the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to …

Aug 20, 2008· From memory, power required is a function of the flow rate and the square of the head. For a worn pump, the flow rate drops as well as the head that the pump can develop so there is an effective cube relationship between power and flow on different pumps... and a worn pump is a different pump from the same model in new condition.
Pump Laws Review and Equations. Centrifugal pumps generally obey what are known as the pump laws. These laws state that the flow rate or capacity is directly proportional to the pump speed; the discharge head is directly proportional to the square of the pump speed; and the power required by the pump motor is directly proportional to the cube of the pump speed.
It takes in water at relatively low pressure and high flow-rate and outputs water at a higher hydraulic-head and lower flow-rate. The device uses the water hammer effect to develop pressure that lifts a portion of the input water that powers the pump to a point higher than where the water started.
Rate of flow (Q) – The rate of flow of a gear pump is the quantity of fluid actually delivered per unit of time, including both the liquid and any dissolved or entrained gases, at stated operating conditions. In the absence of any vapor entering or forming within the pump, rate of flow is equal to the volume displaced per unit of time, less slip.
Note that the total volume flow rate of two pumps operating in parallel is less than twice the flow rate of a single pump operating alone (at the intersection of C and A). Pump Affinity Laws The fundamental fluid mechanic relationships developed thus far can be modified to generate other useful relations between pump/fan parameters.

Some fluid will seep through the gap between the sides of the gears and the endplates (see figure below.) This gap must be small in order to maintain the pressure increase across the pump. Increasing the gap diminishes the pumps ability to hold a pressure difference between the inlet and outlet. The gap is typically around 0.0005 inches.

Feb 26, 2018· Pumps give flow rate, they build up pressure when they encounter resistance, so to say, if you have a pump pumping water into an open container, there will be almost no pressure on that line, but rather flow rate, once you try to throttle the outlet line, flow rate will drop, and the pressure will rise.
degree of internal slippage in a gear pump determines its volumetric efficiency [1] which is the relation between actual pumped fluid flow rate, Q to the losses of flow, QL due to the leakage or slip-back of the fluid around the gear and casing (eqn. 1.1). The mean flow rate of the pump …
