Bareshaftpump
Pump with drive unit
Step 2
On receipt always :
- Check the delivery note against the goods received.
- Ifmotorised,check that thedriveinstructionsare 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 :
- 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 prevent bearing damage.
- All associated ancillary equipment should be treated similarly.

3.2 System design and installation 3. Installation
Step 1
When designing the pumping system :
- Confirm the Net Positive Suction Head requirements of the
pump(NPSHr)aremet,asthisis crucial for wnsuring smooth
operation of the pump and preventing cavitation.
- Avoid suction lifts and manifold/common suction lines for
twopumpsrunning in parallel,asthismay cause vibration or
cavitation.
- Protect the pump against blockage from hard solid objects
e.g. nuts, bolts etc. Also protect the pump from accidental
operationagainst a closedvalveby using eitherreliefvalves,
pressure switch or current limiting device.
Dischargeline
Plan view Suctionline
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.
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.

3. Installation 3.3 Flushed seal arrangements
and pre-start up checks
Step 1
A flushed seal arrangement is fitted in order to cool or clean the seal area.
It is important that :
- The flush is correctly connected (see below).
- A compatible flushing fluid is used and supplied at the correct pressure and flow rate.
- The flush is turned on at the same time/prior to starting the pump, and turned off at the same time/after stopping the
pump.
Step 2
Connecting the flush
The following equipment is strongly recommended when using a flushing system :
- Control valve and pressure gauge, to enable the correct flushing pressure to be obtained and monitored.
- Isolation valve and check valve, so that the flush can be turned off, and to stop any unwanted substances flowing in
the wrong direction.
- A method of visibly indicating flushing fluid flow.
Step 3
Flusing pipework
This suggested arrangement is for single mechanical seals. If
the pump is fitted with double mechanical seals or packed
glands the pressure gauges and control valves should be
fitted on the outlet side of the system.

3.3 Flushing seal arrangement
and pre-start up checks 3. Installation
Step 4
Flushing fluid
Thechoice of flushingfluidis dependent uponthefluid being pumpedandduty conditions i.e.pressureand temperature. Usually
wateris used forcooling or flushingwatersoluble products. Foradvice on selectingasuitable flushing fluidplease contact pump
supplier.
Step 5
Flusing pressure and flow rate
Single mechanical seal 0.5 bar (7 psi) maximum. Any further increase in pressure will result in lip seal failure.
Doublemechanical seal/flushedpackedgland 1.0bar
(14psi) higher pressurethanthe discharge ofthe pump. Ifthe discharge
pressure fluctuates set the pressure to suit maximum condition.
The flushing flow rate must be adequate to ensure that the temperature limitation of the seals is not exceeded. Contact your
pump supplier for further information on the recommended flow.
Step 6
Pre-start up checks
- Check the pipework system has been purged to remove debris.
- Check all obstructions have been removed from pipework and pump.
- Check pump connections and pipework joints are tight.
- Checklubrication levels arecorrect.
- Checkseal flushing is connectedifapplicable.
- Checkall safety guardsare in place.
