l Turn the pump on to its side to
allow access to the baseplate securing
bolts.
l
Remove the three bolts and
washers using a 13mm spanner. As each
bolt is withdrawn, a spacer between the
baseplate and the pump will fall out.
l
Three sets of threaded fixing points
are provided on the pump; the central
set (pictured in use above) allows the
inlet and outlet ports to be positioned
at 10-2 or 2-10; the other sets (one fix-
ing point arrowed) allow the pump to be
positioned with the inlet or outlet horizontal and the other port vertical.
l Pass the bolts with washers through the baseplate and the spacers (Note: the
longer bolt and the longer spacer secure the baseplate to the bearing
housing at the rear of the pump). Screw the bolts into the set of fixing points
appropriate for the desired pump orientation. Tighten to 25Nm using a 13mm
spanner.
13 Possible pump orientations
The pump can be positioned in three orientations, and rotate clockwise or counter-
clockwise.
Counter-clockwise rotation
of the rotor and motor
Clockwise rotation
of the rotor and motor
Unless ordered otherwise, the pump is delivered in position 2-10. Special
customised nozzle orientations are possible.

l Remove the screws on the power frame. Turn the housing by an angle of 45°
to the left or right.
l Refit the screws in their new position and tighten them to the correct torque:
SPS 200: 16 Nm SPS 250: 16 Nm SPS 300: 33 Nm SPS 400: 56 Nm SPS 500: 56 Nm
Note: If the direction of flow is also changed, the gate and gate guide must be
reversed. See 13.2 Changing rotation direction.
