Centrifugal pump Wikipedia

Centrifugal pumps are used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow. The rotational energy typically comes from an engine or electric motor. They are a sub-class of dynamic axisymmetric work-absorbing turbomachinery. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from which it exits. get price

Centrifugal Pumps for sale eBay

Centrifugal water pumps have an impeller inside of them that are often made out of rubber. The motor turns the impeller inside the unit. This, in turn, causes friction to build up to create a suction vacuum strong enough to pull water into it from a source like a river.get price

VFD for Centrifugal Pumps Variable Speed Drives

Historically, fixed speed AC motors have driven centrifugal pumps and reduced flow has been achieved by using control valves as shown in figure 7. Closing the valve reduces the flow by increasing the friction in the system. The modified system curve and the new operating point can be represented as shown in figure 8.get price

Operating a Centrifugal Pump with a Variable Frequency

Operating a Centrifugal Pump with a Variable Frequency Drive. It is increasingly common for pumps to be operated by motors that are controlled by variable frequency drives (VFDs). VFDs control motor speed by varying the frequency of the power being sent to the motor. So a 60 Hz motor operating at 1800 RPM will reduce to 1500 RPM if theget price
