What is a centrifugal pump?

2020/01/10Centrifugal pump is composed of six parts are the impeller, pump, pump shaft, bearing, seal ring, stuffing box. The impeller is the core part of the centrifugal pump, it is high speed, the impeller on the leaves and play a major role, the impeller in the assembly before the static balance through the experiment.

HEADS AND EFFICIENCIES OF A CENTRIFUGAL PUMP

In this post i.e. heads and efficiencies of a centrifugal pump, we will see here the various types of heads and after that we will see efficiencies of a centrifugal pump. Suction Head (h s ) Suction head is basically defined as the vertical distance between the centre line of centrifugal pump and the free surface of liquid (e.g. water) in the tank from which liquid is to be lifted.

Pump Efficiency—What Is Efficiency?

2020/01/05The centrifugal pump converts mechanical energy into hydraulic energy (flow, velocity and pressure), and the AC motor converts electrical energy into mechanical energy. Many medium and larger centrifugal pumps offer efficiencies of 75 to 93 percent and even the smaller ones usually fall into the 50 to 70 percent range.
