3. Installation3.1 Unpacking, Handling and Storage
Step 1
Refer to the pump weights guide (chapter 5) before selecting and using any lifting gear . The drawing show how the pump should
be lifted.
Ensure that lifting equipment is correctly rated and used within these limits.
Pump with drive unit
Step 2
On receipt always :
-Check the delivery note against the goods received.
-If motorised, check that the drive instructions are available.
-Inspect the packing for signs of damage in transit.
-Carefully remove the packing away from the pump.
-Inspect the pump for any visible signs of damage.
-Clean away the packing from the pump port connections.
-Report any damage to the carrier .
Step 3
After receipt and inspection, if the pump is not to be installed immediately , the pump should be repacked and placed in
suitable storage. The following points should be noted :
Bareshaft pump
- Plastic or gasket type port covers should be left in place.
- Pumps received wrapped with corrosion inhibiting treatment material should have wrappiong replaced.
- A clean, dry storage location free from vibration should be selected. If a moist or dusty atmosphere is used for storage, further
protect the pump or unit with a suitable cover.
- Rotate the pump/pump unit by hand weekly, to pr event bearing damage.
- All associated ancillary equipment should be treated similarly .
15
3.2 System design and installation3. Installation
Step 1
When designing the pumping system :
- Confirm the Net Positive Suction Head requirements of the
pump (NPSHr) are met, as this is crucial for wnsuring smooth
operation of the pump and preventing cavitation.
- Avoid suction lifts and manifold/common suction lines for
two pumps running in parallel, as this may cause vibration or
cavitation.
- Protect the pump against blockage from hard solid objects
e.g. nuts, bolts etc. Also protect the pump from accidental
operation against a closed valve by using either relief valves,
Plan view
pressure switch or current limiting device.
Step 2
Before the pump is installed it is advisable to consider the following :
Always
-ensure that the mounting surface is flat to avoid distortion of the baseplate, as this will cause pump/motor shaft
misalignment and pump/motor unit damage.
Check
-pump shaft to motor shaft alignment is within manufacturers limits once the base plate has been secured.
Always allow at least 1 m for pump access/maintenance all around the pump.
- Fit suction and discharge pressure monitor points for diagnostic purposes.
- Fit valves if two pumps are to be used on manifold/common discharge lines.
- Make the necessary piping arrangements if flushing is required for the seal or if media is required for heating/cooling jackets.
- Do not subject the pump to rapid temperature changes. Pump seizure can result from thermal shock.
Discharge line
Suction line
Step 3
All pipework must be supported. The pump must not be allowed to support any of the pipework weight beyond the limits set in
the following table.
Remember :
Pipework supports must also support the weight of the product being pumped.
Always :
- Design short straight suction lines to reduce friction losses in the pipework thereby improving the NPSH available from the
system.
- Avoid bends, tees and any restrictions close to either suction or discharge side of pump. Use ling radius bends wherever
possible.
- Provide isolating valves on each side of the pump to isolate the pump when necessary .
- Keep pipework horizontal where applicable to reduce air locks. Include eccentric reducers on suction lines.

4.4 Assembly4. Maintenance
4.4.6 Adjusting rotor timing
Step 1
If the rotor timing requires adjustment (and assuming the pump has not yet been re-built), it is important to establish the cause for
the rotors mistiming before proceeding.
T o allow timing adjustment ensur e that one shaft is able to rotate within the tor que locking assembly/element. The other torque
locking assembly/element should be tightened to the recommended torque.
Step 2
Locate one rotor (17) on to the drive shaft (24) with the dimple
at the top. T urn the rotor through 45°. Fit the second rotor on
to the auxillary shaft (25) with its dimple at the top as shown.
Dimples
Step 3
Turn the shaft so that the rotors are in the new positions as
shown.
Step 4
Using feeler gauges measure between the points indicated,
turning the shaft as required.
Step 5
If the measurement points are unequal tap the rotor which is on the free turning shaft until equal measurement through 8 points is
achieved.
Step 6
Tighten the torque locking assemblies or clamp plate screws. Confirm timing is still correct. Remove the rotors.

Step 2
Apply liquid gasket to the face of the cover where it mates with the gearcase.
Step 3
Carefully slide the cover over the shaft ensuring the lip seal is
centred and not cut or damaged. Tighten the screws (6).
4.4.8 Fitting and shimming rotorcase
The rotorcase may require re-shimming if new components have been fitted. Back clearances must be checked before operating
the pump.
NOTE !
Y our supplier can advise the correct clearances from the pump serial number. Should they need adjustment follow steps below.
Any incorrect setting of clearances is likely to damage the pump in operation. Shims vary in colour for different thickness, and are
grouped in equal packs at the top and bottom of the rotorcase held in place by shim retainers.
Step 1
1. Remove the shim retainers (8A) and fit one of the thinnest shims (8) to top and bottom position.
2. Replace shim retainers and screws (8B).
3. Fit the rotorcase (9) to the gearcase (1), tighten the rotorcase retaining nuts (4) and fit the rotors (17).
Step 2
The back clearances can now be measured using feeler gauges. The additional shimming required to bring the clearances within
tolerance can be determined, fit additional shims and re-check the clearances.
