Monoblock Pumps Frequently Asked Questions
A monoblock pump is where a motor and pump are combined to form one single compact unit. A monoblock occupies less space and is more efficient as it eliminates transmission losses. Traditionally, a pump system consisted of a pump that needed to be driven by a prime mover. With the advent of electric motors, a motor would be coupled onto a pump, creating a pumpset.
The pump works on the principle of centrifugal force. The source of the rotational energy typically comes from an engine or electric motor. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber, from where it exits.
