1. PRODUCT DESCRIPTION
These operation and maintenance instructions apply to the DESMI SA-pump in Monobloc design.
DESMI SA is a single-stage self-priming centrifugal pump with stainless steel shaft and mechanical shaft
seal. The SA-pump is further equipped with a semi-open impeller which does not choke as
easily as a closed impeller.
The pump is suitable for pumping clean and polluted liquids with temperatures between 0 and 80C. With
special shaft seal up to 120C.
The suction branch of the pump is mounted well above impeller inlet. This is an advantage as the pump
will not - in case of a non-return valve leakage - lose all the priming water and consequently the priming
ability.
The pump has compact structure which provide convenient installation without having toalign the coupling.
As the pump isself-priming, afoot valvewill not benecessary onthe suction line, just asthe pump, contrary
to ordinary centrifugal pumps, will resume pumping if, for a short moment, the liquid has been lowered to
a level below the suction pipe.
The pump is particularly suitable for the pumping of water in connection with e.g. cooling of diesel engines,
as bilge pump, ballast pump, irrigation, washing plants, air conditioning, cooling systems, and sanitary
systems, etc. Furthermore, in the majority of cases where the transport of liquid is required within industry.
1.1 DELIVERY
- Check on receipt that the delivery is complete and undamaged.
- Defects and damages, if any, to be reported to the carrier and the supplier immediately
in order that a claim can be advanced.
2. TECHNICAL DATA

Where index "calc" is the values calculated by the user.
3 . INSTALLATION
3.1 MOUNTING/FASTENING
The pump can be mounted on board directly, and don’t need to spend extra time to align centre line of
pump and motor.
The pump must be installed with horizontal shaft and the pump casing discharge side vertically upwards.
The max. permissible loads on the flanges stated in paragraph 2.2. are to be observed.
The suction line to the pump is to be mounted carefully, so that it is absolutely tight, as even small leakages
may impede the priming. When pumping polluted liquids a strainer is necessary. The strainer must be
equipped with a sieve, the passage area of which is to be 3 x the area of the suction pipe. The mesh size
is to be 1-3 mm smaller than the height of the impeller blades of the pump in question.
The pipes are to be arranged in such a way that stresses resulting from fluctuations in temperature will not
have any effect on the pump. Because of the priming of the pump the pressure pipe is to be arranged so
that water locks in the pipe are avoided. While installing the pump the following must be observed:
- Avoid distortion of the base plate.
- Avoid distortion of the piping system.
At installations pumping hot or very cold liquids, the operator must be aware that it is dangerous
to touch the pump surface, and, consequently, he must take the necessary safety measures.
3.2 WIRING
Wiring to be carried out by authorised skilled workmen according to the rules and
regulations in force.

4. TRANSPORT/ STORAGE
The weights of the pumps in A02/D02 combination (without motor) are stated in the following table:
Pump
Weight(Kg) A/D
SA 25-122
23/25
SA 35-135
41/45
SA 50-180
53/59
Lift the pump by placing the rope around it and see to it that the pump is balanced.
The rope must not bear against sharp edges and corners.
Lifting eyes might be mounted in the pump and used instead.
Before shipment the pump is to be fastened securely on a pallet or the like.
The pump is to be stored in a dry area.
5. INSPECTING THE PUMP
5.1 INSPECTION
When the pump has been dismantled, check the following parts for wear and damage:
- Wear plate/impeller : Max. clearance 0.4 - 0.5 mm.
- Shaft seal/rear cover : Check seat for flatness and cracks.
Check rubber parts for elasticity.
- Bearings : Replace in case of wear and noise.
5.2 FITTING SHAFT SEAL
Before fitting the seat, clean the recess in the intermediate cover. When fitting the seat, remove the
protective coating without scratching the lapped surface. Dip the outer rubber ring of the seat in olive oil
(or another neutral oil). Now press the seat into place with the fingers, and check that all parts are
correctly imbedded.
If it is necessary to use fitting tools, protect the sliding surface of the seat to prevent it from being
scratched or cut. Lubricate the inner diameter of the rubber bellows on the slide ring with olive oil and
push it over the shaft.
The use of a fitting bush as shown on the assembly drawing is recommended to avoid that the rubber
bellows is cut. Push the slide ring over the shaft with the hand. If the rubber bellows is tight, use a fitting
tool and take care that the slide ring is not damaged. If the carbon ring is not fixed, it is important to
check that it is fitted correctly, i.e. the chamfered/lapped side is to face the seat. The carbon ring can be
held by a little grease. When using oil on the shaft, the bellows will settle and seat in about 15 minutes
and until then tightness should not be expected. After start, check by viewing the leak hole that there are
no leaks.
If the pump is equipped with a shaft seal type different from a rubber bellows seal, contact DESMI and
ask for an installation instruction.

5.3 SHAFT
When the pump has been assembled, check that the shaft rotates freely.
6. FROST PROTECTION
Pumps which are not in operation during frost periods are to be drained to avoid frost damage. Remove
the plug at the bottom to empty the pump. Alternatively, it is possible to use anti-freeze liquids in normal
constructions.
7. DISMANTLING
Before dismantling the pump make sure that it has stopped. Empty the pump of liquid before it
is dismantled from the piping system. If the pump has been pumping dangerous liquids you are
to be aware of this and take the necessary safety measures.
If the pump has been pumping hot liquids, take great care that it is drained before it is removed
from the piping system.
8. START-UP
A self-priming centrifugal pump will not function until the pump casing has been
filled with liquid. Remove the plug at the top of the pump casing and fill the pump
with cold liquid. Fit the plug and the pump is ready for service.
The liquid also serves as coolant for the shaft seal. Consequently, the pump
Must under no circumstances be started before it has been primed with liquid.
Furthermore, the pump must never run dry.
WARNING
For safety reasons the pump is only allowed to operate against closed discharge valve for a short time
(max. 5 minutes and at a max. temperature of 80°C for standard pumps). Otherwise there is a risk of
damage to the pump and, at worst, of a steam explosion. If the pump is not monitored, the installation of
a safety device is recommended.
To protect the pump against unintentional operation it is equipped with a relief valve which opens at a
pre-set pressure.
Be careful: When the valve opens, the escaping liquid will be hot.
The relief valve must in no circumstances be removed or re-adjusted!
As regards maintenance of the relief valve - see paragraph 10.
8.1 STARTING
Before starting the pump check that
- The shaft rotates freely without jarring sounds.
- The pump casing is filled with liquid.
Start the pump for a moment to check the direction of rotation. If the direction is correct (i.e. in the
direction of the arrow), the pump may be started.

9. SYSTEM BALANCING
It is often difficult to calculate a manometric delivery head in advance. It is, however, decisively important
to the quantity of liquid delivered.
A considerably smaller delivery head than expected will increase the quantity of liquid delivered, causing
increased power consumption and perhaps cavitation in pump and piping. In the pump the impeller may
show signs of heavy erosion caused by cavitation (corrosion) which may at times render an impeller unfit
for use in a very short time. Not unusually do similar erosions occur in pipe bends and valves elsewhere
in the piping system.
Therefore, after start-up, it is necessary to check either the quantity of liquid delivered or the power
consumption of the pump e.g. by measuring the current intensity of the connected motor. Together with
a reading of the differential pressure the quantity of water delivered can be determined against the
characteristics of the pump.
Should the pump not function as intended, please proceed according to the fault-finding list. Bear in
mind, though, that the pump was carefully checked and tested at the factory and that the majority of
faults stem from the piping system.

10. INSPECTION AND MAINTENANCE
- Before any inspection of the pump, check that the unit cannot be started unintentionally.
- The system is to be without pressure and drained of liquid.
- The repairman must be familiar with the type of liquid which has been pumped as well
as with the safety measures he is to take when handling the liquid.
- Inspect the shaft seal for leaks at regular intervals.
- Activate the relief valve at regular intervals in order to check the function. If the valve is choked,
replace or clean it, if possible.
10.1 DRAINING THE PUMP
When the piping system has been drained, note that there is still some liquid left in the pump. Remove
the remaining liquid by dismantling the pipe plug at the bottom of the pump.
10.2 BEARINGS
The pump is equipped with ball bearings which were lubricated for life before leaving the factory.
Therefore, they require no attention but are to be replaced in case of noise or bearing wear. Place a
bead of grease on the sides of cleaned or newly mounted bearings. As fas as semi-closed bearings are
concerned, place grease on the open side of the bearing only.
A recommended grease quality on a lithium-basis is used:
ESSO ................................................ Beacon 2
BP...................................................... Energrease EP grease 2
Shell .................................................. Alvania grease 2
Mobil.................................................. Mobil lux grease EP 2 or Mobil plex 47
