What is An EN733 Monoblock Centrifugal Pumps?cid=4


A monoblock centrifugal pump is designed with motor and pump body built together without coupling. By sharing one common shaft between the rotor and the impeller, there is less energy loss during the transmission from motor to shaft. The whole pump is constructed as per EN733 standard and suitable for most installations and applications.



The key components of the monoblock are the motor assembly and the pump body assembly. These two parts share one single shaft which makes the pump simple and compact, easy to install and maintain.

The pump assembly adopts 3D theory design that offers best hydraulic efficiency and characteristics related to suction lift and running performance.

Both the rotor and the impeller has taken dynamic balance test, so there is less noise and vibration for the whole pump.

Y series motor adopts cold 800# copper wire which ensures 120% overload and temperature rise△T<80K.
