Monoblock Pump Types and Applications

The pumps which are used in areas like rural, urban, and industrial are called a monoblock pump. These pumps are extensively used from domestic to civil as well as used in industrial applications which include irrigation, agriculture, water supply for building, civil schemes, and water supply for the public, de-watering of mines & for numerous other industrial applications. These pumps are very famous due to their outstanding features like very simple to use, extremely fast, and scalable. This article discusses an overview of monoblock pumps.

What is a Monoblock Pump?

Monoblock pump can be defined as the main mover of the pump namely the motor as well as the pump is assembled jointly within the similar shelter. This is one kind of mechanical device where a general shaft includes the revolving parts. The pump uses well as motor are connected together without using any coupling device in similar housing among the two shafts. As the name suggests mono means solo, whereas the monoblock pump means a pump unit which is inflexibly coupled to prime mover like a motor. The monoblock pump working principle is to avoid the transmission losses where the 3% losses within the coupling driven sets and the 7% of losses within belt driven sets as well as. There is no loss of energy while transmitting energy from the motor to shaft. Generally, these pumps are installed close to the reservoir otherwise well.

Types of Monoblock Pump

The different types of monoblock pumps mainly include centrifugal monoblock pumps, agricultural water pumps, booster agriculture water pumps, and submersible agriculture water pumps.

1). Centrifugal Monoblock Pump

The centrifugal monoblock pumps are mainly recommended for freshwater as well as fluids which are not chemically violent toward the components of the pump. These pumps are mainly used for agriculture, industrial, civil due to their consistency and strength.

The consumers can meet their most demanding requirements, as well as they can change the pumps with other pumps. The monoblock pump design permits dismantling without detaching the body of the pump from the pipeline. These pumps can be used in different conditions.


The performance of these pumps is diverse as well as a wide range which makes it simple to choose the correct model for every application. The performance efficiency of these pumps is high and the operating cost is low.


The internal design of these pumps can be done like this. The pump body is designed with cast iron, designed with delivery ports as well as flanged suction. The mechanical seal housing can be incorporating by the motor bracket or cast iron backplate.

The applications of these pumps mainly include gardens, lawns, car washing, hospitals, hotel, water supply for community, agriculture and domestic water.

2). Agriculture Monoblock Water Pumps

Agriculture water pumps are used for supplying water to agriculture fields. These pumps are mainly used by the farmers to supply the water from ponds, river to their agriculture fields for the purpose of irrigation.

The present modern era of agricultural irrigation is a complex interplay of sustainable energy consumption, required water use, application of experience and knowledge and considering the market condition in order to ensure best designing of irrigation applications.


These pumps are demanded most from the users end due to very smooth in shape as well as in size. These pumps are actually helpful while using in crop fields because these pumps are available without requiring of the base plate as well as coupling. So, monoblock pumps are beneficial economically.

3).Submersible Pump

Submersible pumps are one type of pumps which has a hermetically closed motor and coupled closely to the body of the pump. The entire assembly can be submerged within the liquid to be pushed. The major benefit of this kind of pump is that it stops cavitation of the pump, trouble linked with a high height difference among the surface of the liquid as well as the pump. These pumps push the liquid in the direction of the surface as opposed toward jet pumps having to draw fluids. These pumps are more resourceful compared with jet pumps. These types of pumps are environment-friendly & mainly cost-effective approach for farming irrigation.


4). Booster Pump

A booster pump is one kind of pump which will boost the force of a liquid. These pumps may be used with gases otherwise liquids, however, the structure will differ based on the liquid. A gas booster is related to a gas compressor, however normally a simpler method which frequently has merely a single phase of density, and is utilized to amplify the force of gas already higher than ambient force. Boosters are mainly used for transmitting high force gas, increasing gas pressure, gas cylinders charging, etc.


Operating Parameters

The operating parameters of monoblock pumps vary based on the type of pump. Here we have listed the centrifugal mono block pump parameters which include the following.

  • The power of this pump ranges from 0.50 HP to 2.00 HP
  • The speed of these pumps is 2800 rpm
  • The discharge range of this pump ranges from 27LPM to 900LPM.
  • The whole head range will range from 5 meters to 25 meters.
  • The size of this pump will be 25X25, 40X40, 50X50, 65X65 and 75X75.
  • The suction life with self-priming capability will be 6 meters
  • The sealing of this pump is mechanical.


These pumps are mainly designed to provide the best possible efficiency.

  • These pumps are compact and simple.
  • These pumps are self-supporting.
  • They don’t require extra base plates as well as a coupling for fitting.
  • The overall size is less and less complexity while installing.
  • They are cost effective.

Mono Block Pump Applications

The uses of monoblock pumps include the following.

  • These pumps are used for domestic purposes like gardens, apartments, bungalows, small farms, hospitals, hotels, agriculture, and farm-houses.
  • The centrifugal mono block pumps are mainly recommended for freshwater as well as fluids which are not chemically violent toward the components of the pump.
  • These pumps are mainly used for agriculture, industrial, civil due to their consistency and strength.

Thus, this is all about Monoblock pump, types, and applications. There are many factors we have to keep in mind while selecting these pumps like head, size of inlet & outlet, discharge rate, and construction material. From the above information, finally, we can conclude that it is the main mover of the pump like the motor & pump are connected jointly in similar housing. So, there is no requiring of any coupling device among the two shafts because the shafts are attached straight. Here is a question for you, what are the disadvantages of monoblock pump?
