2. General

If your system is a BME, it has only one pulley head:

• BME pulley head.

For the dismantling of the BME pulley head, go to

page 5 Dismantling of pulley head for BME.

For the assembly of the BME pulley head, go to

page 13 Assembly of pulley head for BME.

If your system is a BMET, it has two pulley heads:

• BME pulley head and

• BMT pulley head.

For the dismantling of the BME pulley head, go to

page 5 Dismantling of pulley head for BME.

For the assembly of the BME pulley head, go to

page 13 Assembly of pulley head for BME.

For the dismantling of the BMT pulley head, go to

page 23 Dismantling of pulley head for BMT.

For the assembly of the BMT pulley head, go to

page 30 Assembly of pulley head for BMT.

Note: To prevent water from mixing with the oil

when the motor-driven pump is removed, proceed

as follows:

• Pull the pulley head with pump out of the sleeve.

• Loosen the pump from the pulley head.

• Proceed as shown in the following illustrations.

GRUNDFOS recommends to replace all gaskets.

The parts required are included in Service kit No.

14 51 77.

Use water/soapy water when fitting the gaskets and

rubber parts, however, not for parts in contact with

oil or bearings.

TM01 1747 5197

During assembly, it must be ensured that the carbon is

never pressed all the way down against the edge of the

steel but just so far that “X” is between 0.5 and 1.0 mm.

Check that the hole in the shaft seal covers the driver pin.
