Design of Centrifugal Pump for Palm Fruit Pulp Handling in Palm Oil Plant.

A B S T R A C T For the design of pump the system resistance (total head) is calculated by considering head and capacity correction factor for 5% consistency of pulp. This factor is taken from data book. Power required and specific speed calculated by standard formulae. For pulp pumps above 3% consistency semi open impeller is preferable. Impeller vane angles, number of vanes, vane curvatures are designed as per standards. Casing is considered as volute type. While designing of volute casing volute angle, throat area and tongue distance are designed as per standards. The shaft is designed as per power required by the pump. Designing of stuffing box and flexible coupling are done based on the shaft diameter by standard proportions. The thrust load and radial loads on the bearings are calculated and deep groove ball bearings are selected for withstanding that loads. The results obtained are compared with the operating parameters of the existing pump in our Palm oil plant and observed that the design is matching with the exist one.
