13 Possible pump orientations
The pump can be positioned in one of eight orientations, and can rotate clockwise or counter-clockwise.
9-12 12-9 10-2 12-3 3-12 2-10
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
13.1 Changing the pump orientation
Disconnect the pump from the mains power, and secure it against-unintentional
start-up.

•
Turn the pump on to its side to allow access to the baseplate securing bolts.
•
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 As each bolt is withdrawn, a spacer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.
•
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 fixing
point arrowed) allow the pump to be positioned with the inlet or outlet horizontal and the other
port vertical.
•
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.

•
Follow the dismantling and assembly steps for your pump model. See "Disassembly and assembly"
on page 38
•
Remove the screws on the power frame. Turn the housing by an angle of 45° to the left or right.
•
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 "Changing
rotation direction" below.
Take care that fluid in the pressure line leaves the pump in an upward direction, so that when pumping
stops, some fluid remains in the pump. This will make it easier for the pump to draw in viscous products
when pumping restarts. This applies particularly when the pressure connection is horizontal: positions
12-3 and 12-9. Take care that the pressure line is run so that the pump rotor is always covered with fluid,
and dry running is avoided.
13.2 Changing rotation direction
When the direction of rotor rotation is reversed, the suction side and the pressure side of the pump are
exchanged. The orientation of the gate and the gate guide must be changed, too, or the pump cannot
pump efficiently.
The pump can run for only a short time with the gate and the gate guide wrongly
oriented, and it will not achieve more than 2 bar pressure. See "Disassembly and assembly" on
page 38. SPS 100 is shown here. All models are similar.
