1. PRODUCT DESCRIPTION
These operation and maintenance instructions apply to the DESMI MODULAR H pump
series. The pumps are available in sizes ranging from 40 to 80 mm on the pressure flange.
The suction flange is bigger than the pressure flange.
DESMI H is a single-stage centrifugal pump with stainless steel shaft, mechanical shaft seal,
and closed impeller.
The pump is suitable for the pumping of clean and polluted liquids with temperatures between
0 and 80°C. With special shaft seal up to 140°C. Max. number of revolutions: 3600 RPM.
The pump has horizontal inlet on the centre line and vertical outlet at the top.
The back of the impeller is equipped with relief blades to reduce the load on the bearings.
Relief holes in the impeller ensure circulation of liquid for the shaft seal and prevent
overheating of the shaft seal during normal operation.

3. INSTALLATION
3.1 MOUNTING/FASTENING
The pump should be mounted and fastened on a solid base plate with a flat and horizontal
surface to avoid distortion.
The max. permissible loads on the flanges stated in paragraph 2.2 are to be observed.
When mounting a V-belt pulley on the pump a bore H7 is recommended. To facilitate the
mounting the hub in the V-belt pulley may be heated to abt. 100°C after which the V-belt
pulley is easily lead over the shaft towards the shoulder. Alternatively, a V-belt pulley may be
mounted with a TAPER LOCK bush.
When dimensioning the V-belt pulley it is important to follow the rules of the DESMI
nomograms for the pump size in question - contact DESMI.
If the pump is to be driven by a motor via a flexible coupling, motor and pump are tobe placed

on a common base plate. The following should be observed:
- Avoid distortion of the base plate.
- Avoid distortion in the piping system.
- Check that pump and motor are aligned correctly.
When connecting the pump and a prime mover the power transmission is to be
equipped with a guard in accordance with the provisions of the COUNCIL
DIRECTIVE of June 14, 1989, on the safety of machines.
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.

5. DISMANTLING
5.1 ACCESS TO IMPELLER AND SHAFT SEAL
Remove Allen screws (22), which hold the shaft seal cover to the pump casing, and pull the
bearing housing to remove the complete bearing housing with impeller, bearings, and shaft.
5.2 DISMANTLING SHAFT SEAL
Remove nut (6). Pull off the impeller. Remove Allen screws (19), which hold the bearing
housing to the shaft seal cover, pull shaft seal cover and bearing housing apart, by which
shaft seal and water deflector are pulled off the shaft.
5.3 DISMANTLING SEAT
Press out the seat from behind the shaft seal cover.
5.4 DISMANTLING SHAFT WITH BEARINGS
Before dismantling the shaft with bearings, remove the sunk key (16). The shaft can now be
pulled out of the bearing housing allowing inspection of the bearings.
5.5 INSPECTION
When the pump has been dismantled, check the following parts for wear and damage:
- Sealing ring/impeller: Max. clearance 0.4-0.5 mm measured in radius.
- Shaft seal/shaft seal cover: Check the seat for flatness and cracks.
Check the rubber parts for elasticity.
- Bearings: Replace in case of wear and noise.
6. ASSEMBLING
6.1 FITTING SEALING RING IN PUMP CASING
When fitted, the sealing ring is to bear against the shoulder of the pump casing.

6.2 FITTING SHAFT WITH BEARINGS
Lead shaft with bearings into the bearing housing. Fit sunk key (16).
6.3 FITTING WATER DEFLECTOR
Assemble the bearing housing and the shaft seal cover. Lead the water deflector over the
shaft until it touches the shaft seal cover and then further 1-1.5 mm into the shaft seal cover.
6.4 FITTING SHAFT SEAL
Before fitting the seat, clean the recess in the shaft seal cover. When fitting the seat, remove
the protective coating without scratching the lapped surface. Dip the outer rubber ring of the
seat into
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 tools for assembling, then protect
the sliding surface of the seat to prevent it from being scratched or cut. Lubricate the inner
diameter of the slide ring rubber bellows 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.
6.5 FITTING IMPELLER
Fit the sunk key in the shaft and lead the impeller towards the shoulder of the shaft. Take
care that the ring at the end of the shaft seal spring locates in the recess of the impeller.
Secure the impeller with a washer and a nut.
6.6 FITTING BEARING HOUSING AND SHAFT SEAL COVER
Place the gasket between pump casing and shaft seal cover on the shaft seal cover where it
can be held with a little grease. Fit and fasten bearing housing with shaft seal cover. Check
that the drain passage for the shaft seal faces downwards.
6.7 SHAFT
When the pump has been assembled, check that the shaft rotates freely.

7. FROST PROTECTION
Pumps which are not in operation duringfrost 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.
8. 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.
9. START-UP
A centrifugal pump will not function until it has been filled with liquid between the
foot valve and somewhat above the impeller of the pump.
The liquid also serves as coolant for the shaft seal. In order to protect the shaft seal the pump
must not run dry.
ATTENTION
For safety reasons the pump is only allowed to operate against closed suction and discharge
valves for a short time (max. 5-10 minutes and at a max. temperature of 130°C). Otherwise
there is a risk of damage to the pump and, at worst, of a steam explosion. If the pump room
is unmanned, the installation of a safety device is recommended.
9.1 STARTING
Before starting the pump check that:
- the shaft rotates freely without jarring sounds.
- the pump casing and the suction line are 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.

10. 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.

11.1 DRAINING THE PUMP
When the piping system has been drained, note that there is still liquid in the pump.
Remove the liquid by dismantling the pipe plug (75) at the bottom of the pump.
11.2 BEARINGS
The pump is equipped with ball bearings with a nominal life of 25,000 working hours when
direct coupled to electric motor, whereas the nominal life with overhanging V-belt drive is
about 10,000 working hours. The bearings are lubricated for life and require no attention but
are to be replaced in case of noise or bearing wear.
