Two-Stage Series And Parallel Pumps
Product Code : LSK-FM-10436
Two-Stage Series And Parallel Pumps (SKU LSK-FM-10436) is a compact, mobile and self-contained test rig with two centrifugal pumps that students run alone, in series or in parallel to compare their characteristics. It is used in fluid machinery labs for engineering degrees, diplomas and technical training. Made by Science Lab Supplies in its Saha, Ambala plant (Plot 448, HSIIDC Industrial Area, India), it is sold factory-direct to universities, polytechnics, tender contractors and distributors.
Specifications
Two bearing-mounted motors drive the pumps independently, each with its own electronic Motor Drive, torque load cell and speed sensor; every drive display shows speed and torque and calculates true shaft power. A two-way valve switches between single, series and parallel running, and a Venturi meter gives the flow rate.

Applications and Experiments for the Series and Parallel Pumps
The rig shows how combining two centrifugal pumps changes the system: series operation raises head, while parallel operation raises flow. Students plot head and efficiency against flow for each arrangement, observe cavitation through the pump windows and measure flow with a Venturi tube.
- Pump performance: head versus flow and efficiency versus flow.
- Operation of centrifugal pumps in series and in parallel.
- Demonstration of cavitation.
- Non-dimensional performance characteristics for B.Tech fluid machinery labs.
Standard Scope of Supply
The rig is supplied as one self-contained unit: two centrifugal pumps with bearing-mounted motors, integral reservoir, strainers, inlet valves, two-way valve, Venturi meter, and the instrument frame with a Motor Drive and display for each pump. The stroboscope for viewing cavitation is optional.
Packing, MOQ and Lead Time
A quotation can be made for one rig or for a lab-wide order, and it states the packing, delivery time and price for whatever quantity you specify. Pressure displays or other fluid mechanics lab experiments can be listed on the same quotation.

Frequently Asked Questions
How do students switch between series and parallel?
A two-way valve in the system sets the pumps to run alone, in parallel or in series, and each pump has its own inlet valve, so the change needs no pipework alterations.
Can each pump run at a different speed?
Yes. Each pump has its own motor and electronic Motor Drive, so speed is set independently and each display shows that pump's speed, torque and shaft power.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures this rig itself, at its factory in Saha, Ambala, India. You deal with the maker from enquiry to dispatch, and the quotation comes from there.
Is this rig suitable for a tender?
Yes. Send the tender specification and quantity, and an item-wise quotation is returned against the features listed above.
