Variable Speed Series and Parallel Pumps
Product Code : LSK-FM-10432
Variable Speed Series and Parallel Pumps (SKU LSK-FM-10432) is a compact, bench-top test set for finding the characteristics of centrifugal pumps running singly, in series or in parallel. It suits B.Tech and polytechnic fluid mechanics practicals. Science Lab Supplies, a laboratory equipment manufacturer in India, builds the rig at its Plot 448 factory in the HSIIDC Industrial Area, Saha, Ambala, and quotes it directly to colleges, tender contractors and distributors.
Specifications
The set pairs one variable speed and one fixed speed centrifugal pump, each driven by its own bearing-mounted motor. Both draw from a clear acrylic reservoir; valves route the water to a flow and temperature measurement device and back again, so the same water is reused and consumption stays minimal.

Applications and Experiments for the Series and Parallel Pumps
Students plot head and flow characteristics for one centrifugal pump, then compare them with two pumps in series (higher head) and in parallel (higher flow). Changing the speed of one pump shows how speed shifts the pump curve, a core fluid mechanics lab experiment in engineering courses.
- B.Tech fluid machinery lab: head–flow characteristic of a single pump.
- Series operation: adding the heads of two pumps at one flow rate.
- Parallel operation: combining flow rates at a common delivery pressure.
- Effect of pump speed on the curve, read from the intake and delivery transducers on the control box.
Standard Scope of Supply
Each set is supplied complete: both centrifugal pumps with their bearing-mounted motors, the clear acrylic reservoir, the valve network with adjustable inlet and delivery valves, the flow and temperature measurement device, both pressure transducers and the control box with its display.
Packing, MOQ and Lead Time
Quotations can be prepared for one test set or for enough units to equip a whole fluid mechanics laboratory. Each one sets out the packing, delivery time and price for the quantity requested, and other engineering lab equipment in India can be listed alongside it.

Frequently Asked Questions
Can the two pumps be tested separately?
Yes. Each pump has its own bearing-mounted motor, so either can run alone for its own characteristic, and both can then be connected in series or in parallel through the valves.
Does the rig need a separate water supply while running?
No. The pumps draw from the clear acrylic reservoir and the water returns to it after passing the valves and the flow and temperature measurement device.
Who makes this pump test set?
Science Lab Supplies makes it in its own workshop in Saha, Ambala, India. We are the manufacturer rather than a trading agent, so your quotation is issued by the factory itself.
