Monoblock Pump vs Centrifugal Pump[10 points]

We all know that pumps are the equipment to create a movement in the fluids through some sort of mechanical activity. On basis on the mechanical action, pumps have many classifications like gravity, steam, velocity and valve less pumps. So, in this article we are going to have our discussion on difference between “Monoblock Pump” and “Centrifugal Pump” or monoblock pump vs centrifugal pump[10 points].

Monoblock pump

A monoblock pump is device which is a single segment, horizontal and end suction pump equipped either with a partially closed or impeller. In monoblock pump, all the revolving parts of the device are fitted on a single shaft. The elimination of friction loss of this pump is the unique feature. It means that when using other pump, there exist around 3% to 7% losses in coupling and belt-driven sets, but monoblock pumps have the capacity to eliminate these losses.  On the circumstances of size and power of the pump, the monoblock uses in domestic and small commercial activities.

Centrifugal Pumps

Like monoblock pump, centrifugal Pumps works on circulating water by the conversion of rotational kinetic energy to the hydrodynamic energy of water flow.  An electric motor is used to derive rotational energy. The Jet Centrifugal pump is also other kind of a centrifugal pump which works on similar mechanism. It uses a stream of sucked water for creating a jet to improve the drawing capacity from the underground resources. These pumps are suitable for domestic water supply, lawn sprinklers, gardens, small farms, irrigation, agricultural applications, draining of wells and tanks, filling water in swimming pools, etc. These pumps have higher discharge compared to regenerative pumps

Monoblock pump vs Centrifugal pump

FeatureMonoblockCentrifugal
Working principleAll rotating parts are mounted on a common shaft.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/casing, from where it exits.
SpaceComparatively small in size and hence occupies less space.Occupies a more space as the assembly is kept on a platform or different platform.
Flow rateLessHigh
Power consumptionLessHigh
MaintenanceTaking less time and moneyTaking more time and money
ApplicationWorks well for domestic applications.Works well when a high amount of liquid discharge is required.
LocationAssembly can be kept at a distance from water source or nearer.Assembly can be kept at a distance from water source, saving immediate space.
Energy LossLessComparatively high
Over heatIn low water flow, pump is not overheatIn low water flow, pump may overheat
PriceLessHigh

Conclusion

Thus, this is all about Monoblock pump vs Centrifugal pump. Before selecting any pump this difference may able to help you lot. Rather than there are many factors we have to keep in mind while selecting these pumps like size of inlet & outlet, discharge rate, head, and construction material. From the above information of monoblock pump and centrifugal pump difference, finally, we can conclude that both monoblock and centrifugal pump have different type of features and applications.
