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 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.
