SUBMERSIBLE PUMP TEST APPARATUS Model FM 13S

The Sci-tech Submersible Pump Test Apparatus Model FM 13S has been designed to enable students to study the operation and performance characteristics of a typical centrifugal pump. The module consists of a variable speed centrifugal pump assembly having an independent discharge manifold interconnected by plastic tubing with quick release connectors. The pump is driven by a DC shunt wound motor of adjustable speed. The motor is suspended and the driving torque is determined with a torque wrench. The motor speed and power consumption are digitally displayed on the control panel. The pump can be connected to the FM 100 Hydraulic Bench or any other hydraulic bench models to supply and re-circulate water. Bourdon tube pressure gauges are mounted at the inlet and exit of the pump to measure increase of head across the pump. The independent discharge manifold has a pressure gauge and a flow control valve upstream of the discharge pipe and the diffuser. The flow rate through the system is measured using the measuring tank of the hydraulic bench and can be checked independently by the water flow meter fixed in the discharge.

The Sci-tech Submersible Pump Test Apparatus Model 13S is a compact unit and all components and instrumentation are placed in a robust and mobile frame. The complete unit is manufactured from corrosion resistant material.

Item Description

Submersible pumps are widely used for pumping liquids in several applications including domestic, industrial, irrigation and drainage. Energy is supplied to the pump by an electric motor and the potential energy of the liquid is increased by the action of the impeller rotating inside a volute casing. It is essential for students to understand the operation and performance characteristics of centrifugal pumps. The Sci-tech Submersible Pump Test Apparatus Model FM 13S is an experimental set-up necessary for any Fluid Mechanics and Hydraulics Laboratory of an educational institution.
