Technology of centrifugal pumps in closed circuits N°10 – Summary exercises – part 1 training – NVQ level

Indicate from memory all the specific characteristics of each of the pumps in the photo below (size, name, type of motor, type of connection, etc.):

Example:

Answer:

This pump is a large single norm type pump.

  • The suction is horizontal and its discharge vertical
  • Its suction diameter is greater than the discharge diameter
  • Its motor is not connected
  • It is to be fixed to a block with a base plate
  • It will be connected to pipes between flanges and anti-vibration sleeves.

Question  

Indicate all the specific characteristics of the pump in the photo below (size, name, type of motor, type of connection, etc.).
This is a large single in-line pump.
– Its suction and discharge elements are aligned and of the same diameter.
– Its motor is a dry rotor ansynchronous dry rotor motor.
– It is fixed to a block with a base plate.
– It could be fixed directly to a pipe if it can support the weight.
– On the block, it will be connected between flanges and anti-vibration sleeves.

Question  

Indicate all the specific characteristics of the pump in the photo below (size, name, type of motor, type of connection, etc.).
This is a small single in-line pump.
– it is called a circulator or accelerator.
– it has a wet rotor asynchronous motor.
– It will be connected to pipes between union connections.

Question  

Indicate all the specific characteristics of the pump in the photo below (size, name, type of motor, type of connection, etc.).
This is a large double in-line pump.
– the suction and discharge elements are aligned and of the same diameter.
– its motor is a dry rotor asynchronous dry rotor motor.
– It is fixed to a block with a base plate.
– It could be fixed directly to a pipe if it can support the weight.
– on the block, it will be connected between flanges and anti-vibration sleeves.
– It can operate “in parallel”.

Question  

Indicate all the specific characteristics of the pump in the photo below (size, name, type of motor, type of connection, etc.).
This is a large single base plate mounted norm pump.
– its suction is horizontal and its discharge vertical.
– the suction diameter is greater than the discharge diameter.
– its motor is a dry rotor asynchronous dry rotor motor.
– it is to be fixed to a concrete block.
– it will be connected to the pipe between flanges and anti-vibration sleeves.
