Series and Parallel Pump Apparatus (MODEL ME-FM-1299E-R)

The ARL’s 1299E unit is designed to demonstrate the operational advantages of parallel or series operation, depending on the required duty.

Centrifugal pumps are often used together to enhance either the flow rate or the delivery pressure beyond that available from the single pump.

  • This 1299E centrifugal pump demonstration Apparatus, comprising of a water reservoir, the pump, control valves and interconnecting pipework all mounted on a stainless steel base
  • Equipped with electronic measurement sensors for pump head pressure, suction, flow rate and water temperature
  • Transparent pump volute for visibility
  • Capable of being linked to a PC , which does not require internal access to the computer Also enables interfacing to other software packages
  • Supplied with software providing full instructions for setting up, operating, calibrating and performing the teaching exercises. Facilities for logging, processing and displaying data graphically
  • Offers a complete teaching package of coursework and laboratory investigation
  • Demonstration of either series, parallel or single pump operation
  • Measurement of constant-speed pump performance, including production of characteristic curves (one pump)
  • Comparison of head-flow characteristics with single pump operation, at inherent speed
  • Investigation of impeller styles
  • Comparison of student calculations with computer results

Two motor-driven centrifugal pumps, mounted on a stainless steel plinth with a water reservoir and pipework for continuous circulation. The pumps can be configured for single pump operation, two pumps in parallel or two pumps in series by using manually operated ball valves. Similarly, manual valves are used to control the flow and facilitate the study of suction effects, including demonstration of air release.

In parallel operation the two pumps draw from a shared inlet pipe of a wider diameter than the pump inlet, reflecting a typical industrial configuration of parallel pumping. Each pump has impellers that can be easily accessed and replaced without tools, one with forward curved blades and two with backward curved blades, allowing the students to investigate the effects of impeller characteristics.

Electronic sensors measure the pump outlet pressure of each pump, the shared pump inlet pressure, the flow rate and the water temperature.

Max flow rate:2.2 l/s (parallel pumping, both pumps 50Hz)
Max head:6.0m (single pump)
12.0m (series)
Max pump speed:1,500rpm (pump 1)
1,500rpm (pump 2)
Motor power rating:450W

The analogue output data is digitized and transferred to a computer. This allows any standard modern Windows computer to be used, including notebooks, and does not require any internal access to the computer.

The equipment is supplied complete with a USB lead for connection to the computer.
