Pumps with a stainless steel power frame and a single mechanical
seal: dismantling the pump housing
l Guide the optional special cylindrical tool (arrowed: TL-SP21-002-50,
TL-SP25-002-50, TL-SP40-002-50 or TL-SP50-002-50 - available to
order) over the shaft and push it home. This will give some protection
to the shaft splines as the pump housing is removed. Otherwise, it is
important not to damage the shaft while removing or installing the
pump housing.
l Use a 13mm spanner to loosen and remove the six screws (right-
hand thread) and washers which secure the pump housing to the
power frame.
l If necessary, gently tap the pump housing with a soft hammer to free
it. Withdraw the pump housing carefully.
Note: the pump housing is heavy.
l Pull off the flush ring.
Note: See page 81 for dismantling the pump housing of a pump with a cast iron
power frame.
