Overview

Centrifugal Monoblock Pumps are a popular type of water pumps used in India. They gain their name due to the fact that they work through a centrifugal force from its centrifugal electric motor. They are installed on a dry surface protected from rainfall and operate and pump water from the source to the intended storage/usage through an electrical motor and pump connected vide a single shaft (monoblock).

How does a monoblock pump work?

Monoblock are surface pumps and the water is pulled through the suction pipe to the eye of the impeller. The water enters through the impeller eye, gains kinetic energy, and gets pushed out to the volute by centrifugal force. The volute, a stationary chamber with a gradually increasing area, converts the kinetic energy of water to pressure (head), as the water is delivered to the point of use. These pumps can either work in negative suction (where the pump is above the water level) or in positive suction (where the pump is below the water level but not submerged, e.g. overhead tank)

Monoblock pump applications are limited by suction lift while working in negative suction. Considering the friction losses in the pipeline, the suction lift is limited to 6 m. The suction lift, a negative pressure at the suction side, is the pressure gradient between the hydraulic centre of the pump and the level of water surface in the well or tank. Check our Monoblock Pump FAQs which provide more detailed information on how they work.

How to install a monoblock pump?

Monoblock pumps are mounted on a level concrete foundation using appropriate bolts. Use the recommended pipe size on the suction and the delivery side.  Install the pump such that the distance from the pump centre (hydraulic centre) to the surface of the water in the well or tank is less than 3 m. Attach a foot valve at the end of the suction pipe and ensure that it is sufficiently submerged in water. Reduce pipe fittings at the suction line to minimize losses. Protect the pump set from rain and dust by having a properly ventilated enclosure. Check our Monoblock Installation page for more information.
