Performance curve for Vacuum pump Performance curve for Compressor Each G-2RB type can be applied both as vacuum pump and compressor in continuous operation over the total stated performance curve range. The motors are available as standard for the input voltage range of 50 and 60 Hz and for ...
Output includes error signal computed from input parameters, and is used to drive an electrically operated gate valve to automatically throttle the discharge pressure or RPM to meet each pump's unique performance curve. Device records and stores operating maintenance data of pumps. Computer stores ...
How to read a pump performance curve remains a topic of great interest across the food, dairy, beverage, and pharmaceutical processing industries, so in this post we provide important information on two of our most popular styles — Centrifugal and Positive Displacement. A pump performance curve ...
Pump Performance Curve The pump characteristic is normally described graphically by the manufacturer as the pump performance curve. The pump performance curve describes the relation between the flowrate and the head for the actual pump. Other important information for a proper pump selection is also i...
Suppression of performance curve instability of an axial-flow pump by using a double-inlet-nozzle[J]. International Journal of Rotating Machinery, 2014, 2008: 7.Perez Flores P,Kosyna G,Wulff D. Suppression of per- formance curve instability of an axial-flow pump by using a double-inlet-...
(PSI), or feet of water. The first point on the curve is generated by closing the regulating valve all the way to “deadhead” the pump, and measuring the pressure on the gauge. Next, the valve is slowly opened until, say, 5 gpm shows on the flow meter, and the resulting pressure ...

The solid curve indicates Eq. (4), ∆UTP=∆USP/(1−α), where ∆USP was obtained from the single-phase calibration data. It was considered that the de- viation of the measured data from the calculated curve was caused of the measurement limitation of the void fraction with the ...
