Variable Speed Series And Parallel Pumps
Variable Speed Series And Parallel Pumps (Product Code: SLE/EFM/29) is a bench-top test set for studying how centrifugal pumps perform on their own and when two are combined in series or in parallel. It pairs one variable speed and one fixed speed centrifugal pump, each driven independently by its own bearing-mounted motor, drawing from a clear acrylic reservoir. The set is built for fluid machinery and hydraulics laboratories in engineering and diploma institutions by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a technical educational equipment manufacturer.
Key Details
| Parameter | Detail |
|---|---|
| Type | Bench-top centrifugal pump test set |
| Pumps | One variable speed centrifugal pump and one fixed speed centrifugal pump |
| Drive | Two bearing-mounted motors, each driving one pump independently |
| Operating modes | Single pump, two pumps in series, two pumps in parallel |
| Water supply | Clear acrylic reservoir; water returns to it for re-use, keeping water use to a minimum |
| Circuit | Water passes through a series of valves to a flow and temperature measurement device |
| Operating conditions | Set with adjustable inlet and delivery valves |
Typical Use
A standard sequence begins with one pump running alone. Students close the delivery valve in steps, recording flow at each setting to build the pump's characteristic, then repeat at different speeds on the variable speed pump to see how the curve shifts. Next they valve the two pumps into series, which adds head for the same flow, and then into parallel, which adds flow at a similar head. Plotting all the curves on one chart makes the difference between the two arrangements clear and shows why the choice matters when matching pumps to a real piping system.
Because one pump is variable speed and the other fixed, the set also lets students explore what happens when unequal pumps share a duty, a situation common in building services and water supply. The inlet valves can be throttled to create more demanding suction conditions. With a closed water circuit and a transparent reservoir, it is a tidy, visible choice of engineering lab equipment in India for colleges, polytechnics and TVET centres.
Manufacturer

Related Fluid Mechanics Equipment
Apparatus often chosen with this set for a fluid machines course:
- Two Stage (Series And parallel) — an alternative two-pump rig that uses a Venturi meter for flow measurement
- Axial Flow Pump Module — contrasts centrifugal behaviour with a different rotodynamic pump type
- Cavitation In Venturi — shows the cavitation limits that affect pump suction design
- Friction Loss In Pipe — measures the pipe losses that make up the system curve a pump works against

Frequently Asked Questions
Can each pump be run on its own?
Yes. Each pump has its own bearing-mounted motor, so either can run alone, or both can be combined in series or in parallel.
Why is one pump variable speed and the other fixed speed?
It lets students see how speed changes a pump's performance and how two unequal pumps behave when they share the same flow path.
What is measured on the set?
Water is delivered to a flow and temperature measurement device. Details of any pressure or head instrumentation, and of motor ratings, are not in our current description, so please contact us for the datasheet.
Does it need a mains water connection?
No continuous supply is described: the pumps draw from the clear acrylic reservoir and the water returns there for re-use.
How should the reservoir be maintained?
Use clean water, drain the reservoir if the set will stand unused for long periods, and wipe the acrylic with a soft cloth to keep it clear.
What details help with a tender or institutional quotation?
Send the quantity, installation site, electrical supply available at your lab and any tender specification sheet. Warranty terms are included in our quotation.
Is export supply possible?
Yes, the set can be supplied within India and to international markets; shipping arrangements are agreed when you order.
