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.).

Question  

Indicate all the specific characteristics of the pump in the photo below.
This is a small single variable port to port pump to be installed in-line.
– It has a asynchronous or induction wet rotor motor.
– the circulator is known as a zoom.
– It will be fixed to pipes between oval flanges.

Question  

Indicate all the specific characteristics of the pump in the photo below.
This is a medium sized double pump.
– It has wet rotor motors.
– It is installed in-line between flanges.
– it can operate “in parallel”.

Question  

Indicate all the specific characteristics of the pump in the photo below.
This is a large single in-line pump.
– its suction and discharge are aligned and of the same diameter.
– It has a dry rotor asynchronous motor.
– It is to be fixed to a block by 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.
This a very large split casing pump.
– Its pump casing consists of two parts separated by the split casing.
– Its suction and discharge are aligned and of the same diameter.
– It has a dry rotor asynchronous motor.
– It is to be fixed to a block by a base plate.
– It will be connected between flanges.
