Electric Motor Driven Pump

The diaphragm metering pump offers a number of power end versions also suitable for use in areas at risk from explosion.

Electric motor driven pump.

The centre section of this pump is filled with pressurised air and is mechanically moved left right by the motor so it pushes and pulls the diaphragm from left to right. Install both a union and a gate valve not furnished on the discharge side of the pump for service convenience. Robust motor driven metering pumps like the sigma 2 basic guarantee excellent process reliability with their patented multi layer safety diaphragm. Support the piping independently of the pump to avoid universal or excessive stresses on the pump casing which would cause impeller misalignment and possible pump failure.

Ac motor main drive controller assembly and drive operator interface. As a general rule electrical motor pumps are installed for use in emergencies or during ground operations. The difference from an air operated diaphragm pump is the centre section of this pump as it uses an electric drive instead of compressed air.

A variable frequency drive is a device used in a drive system consisting of the following three main sub systems. Hp psi x gpm 1714 x 0 85. Some aircraft can deploy a ram air turbine rat to generate hydraulic power. Electric motor driven pumps can be used as primary supplemental or emergency backup hydraulic power in a variety of aerospace applications.

The ac electric motor used in a vfd system is usually a three phase induction motor some types of single phase motors or synchronous motors can be advantageous in some situations but. Assuming a pump efficiency of 85 which would be representative of most positive displacement pumps. Figures in the body of this table show the horsepower needed to drive a positive displacement hydraulic pump and would be valid either for electric motor or engine drive. Electric motor driven pumps 3.

Both dc and ac motors with full control are available and can be adapted to the application s individual need.
