5.5 Base plate

Single-head pumps (except TP 25-50, 25-80, 25-90,
32-50, 32-80, 32-90, 40-50, 40-80 and 40-90) have
two tapped holes in the bottom of the pump housing
which can be used for fitting a Grundfos base plate
to the pump. The base plate is available as an
optional extra.
Twin-head pumps have four tapped holes in the
bottom of the pump housing. For some twin-head
pumps, a base plate consisting of two halves is
available.
Base plates with dimensions are shown on page 32.

5.6 Insulation

Do not insulate the motor stool as this will
trap any vapour escaping from the shaft
Caution seal, thus causing corrosion. Covering the
motor stool with insulation will also make
inspection and service difficult.
