Series & Parallel Pump Test Apparatus MODEL FM 12
The Sci-tech Series & Parallel Pump Test Apparatus Model FM 12 is an experimental set-up necessary for any Fluid Mechanics and Hydraulics Laboratory of an educational institution.
Item Description
Pumps are connected in series and parallel to obtain the required flow rate and head in several applications including domestic, industrial, irrigation and drainage. Energy is supplied to the pumps by electric motors 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 operating in both series and parallel connection.
The Sci-tech Series & Parallel Pump Test Apparatus Model FM 12 has been designed to enable students to study the operation and performance characteristics of typical centrifugal pumps connected by flexible tubing and valves to operate in both series and parallel mode. The apparatus can also be used to conduct experiments on a single centrifugal pump independently.
The apparatus consists of two similar variable speed centrifugal pumps having independent discharge manifold connected by plastic tubing with connectors to enable quick change of operation to series or parallel modes. Shut-off valves in the pipe system enable the pumps to be connected in series or in parallel. Pumps are driven by a DC shunt wound motors of adjustable speed. Motors are suspended and the driving torque is measured using torque wrench. Motor speeds and power consumption are digitally displayed on the control panel.
The apparatus can be connected to the Scitech 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 pumps to measure increase of head across the pumps. The independent discharge manifolds have pressure gauges and flow control valves upstream of the discharge pipe and the diffuser.
The flow rate through the pump system is measured using the measuring tank of the hydraulic bench and can be checked independently by water flow meters fixed at the delivery side of both pumps. The Sci-tech Series & Parallel Pump Test Apparatus 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.
