CENTRIFUGAL MONOBLOCK PUMPS AND APPLICATIONS

What is a Monoblock Pump?

          Monoblock Pump is defined as, the prime mover of the pump i.e.,, the motor and the pump is assembled together within the same housing. In this type of pumps there is no need of any coupling between the motor shaft and pump shaft since the shafts are coupled directly. The main principle of monoblock of pump is to transmit power without any losses. 

          In Monoblock Pumps, Centrifugal monoblock pump is one of the common types. In a lot of places centrifugal pumps offers more benefits. Here are the benefits offered by these pumps:

1) Due to its compact size, it consumes less space.

2) There is no air lock problem in these types of pumps, because these have uni casing.

3) There is no centrifugal switch.

4) The pump has a balanced structure so there is no vibration and noise. Rigged construction that ensures longevity.

5) There is less maintenance & operation cost.

6) Bearings of the pump are water lubricated.

7) These pumps are self-supportive. This means that there is no requirement of installing any base plate or guards.

8) These pumps have the best hydraulic and suction lifting efficiency.

9) They are self priming. They are also put into use to pump water from well (Both shallow and deep wells) with built in Non return valves.

Applications:

          These pumps can be used at a variety of places to meet different water requirements. Below we mentioned some applications of these type of pumps:

a) Industrial and Public water supply.

b) Booster application

c) Sprinkler/Drip and Lift Irrigation

d) Dewatering of mines.

MONOBLOCK PUMP TYPES AND APPLICATIONS

          A Monoblock Pump is a mechanical device. We all know that 'Mono' means single. The prime mover of the pump (i.e., Motor) and pump are built together in same housing, that type of pumps is called as "Monoblock Pumps".

          In which a common shaft contains all the rotating parts. Because of this, during the transmission from motor to shaft, loss of energy is minimal. Motor assembly and pump assembly is the main components of monoblock pumps. The device's impellor and volute chamber are designed in a manner that it offers best hydraulic efficiency and characteristic related to suction lift. Most advanced machinery, dynamic balanced impellor, seals and ball bearings are used for the manufacturing process. Due to the dynamically balanced rotor, there is less noise and vibration. The shaft is made up of high-quality steel.

Types of Monoblock Pumps:

          Different types of monoblock pumps are available in the market, mainly include

              1) Centrifugal Monoblock pumps

              2) Submersible pumps

              3) Booster pumps 

Features/Advantages: –

a) It's unique design that helps in the prevention of overloading and the burning of the motor even during prolonged use.

b) They are simple and compact. They need less space for installation.

c) They are cost effective.

d) Weared parts can be easily replaceable.

e) These pumps bears fatter efficiency curve which helps in efficient functioning.

f) With dynamically balanced rotating parts, there is less noise and vibration while working.

g) The pump has less complexity in installation and maintenance is also easy.

h) They are self supporting, these pumps do not need additional base plates and coupling for installation.

i) Automatic release of air while priming.

j) These pumps has a sturdy design as they can endure three phase voltage fluctuations.
