What is a monoblock pump?
The impeller is mounted on the extended shaft of the motor, so the pump and motor form one compact unit with no coupling or alignment to adjust. Water is drawn in by suction and delivered at pressure. The design is simple and low in cost, so it is common in homes, farms, buildings and small industries.

List your companyMonoblock Pump or borewell submersible pump?
A monoblock pump sits above ground, is easy to inspect and service, and works well for shallow sources and boosting. A submersible pump works underwater, needs no priming and can lift from much greater depths.
What to specify when you ask for a quote
- Flow and total head at the duty point, including suction lift.
- Suction and delivery size, and whether the pump must be self-priming.
- Motor rating, phase and voltage range.
- Materials of the impeller and casing for the liquid being pumped.
- Certification marks required for your use and the warranty offered.
- Spares for seals and bearings, and a service contact near you.

Frequently asked questions
What is a monoblock pump used for?
It lifts and moves clean water from a tank, well or sump for homes, farms and buildings, and boosts pressure in pipework.
What does self-priming mean?
A self-priming pump can draw water up the suction pipe without being filled first, which is convenient when the water level is below the pump. Ask whether the model you want is self-priming.
How far can a monoblock pump lift water?
It depends on the model, but suction lift is limited, so monoblock pumps suit shallow sources. For deep wells a submersible pump is the right choice.
How should a monoblock pump be installed?
Mount it on a firm, level base as close to the water as practical, with a short, straight suction pipe that is airtight and as large as the pump inlet. Use a foot valve where the pump is not self-priming, and fit protection for the motor.
