(–90 m) TwoVane Impellers Twovane impellers feature large passageways, wellrounded leading vanes, and a thick hydrofoil shape to prevent long stringy material from wrapping around the leading edge. This design channels fluid away from the impeller vanes into the circular flow
illustrated in the figure The semiopen impeller with pumpout vanes and the closed impeller with two wear rings and balance holes are most common in petrochemical and paper mill process applications. The point of highest pump efficiency is called the "Best Efficiency Point" or BEP. This is the pump design point and the

Pump Data Pump Flow Rate The pump flow rate or capacity Q is the useful volume of fluid delivered to the pump discharge nozzle in a unit time in m /s (l/s and m /h are also used in practice, as are GPM in the US). The flow rate changes propor tionally to the pump speed of rotation. Leakage flow as well as the internal clearance flows

A centrifugal pump is one of the simplest pieces of equipment in any process plant. Its purpose is to convert energy of a prime mover (a electric motor or turbine) first into velocity or kinetic energy and then into pressure energy of a fluid that is being pumped. The energy changes occur by virtue of two main parts of the pump, the impeller
