TM06 9156 1717

These dimensions are stated on page 26:

• port-to-port lengths

• dimensions of the base plate

• pipe connections

• diameter and position of anchor bolts.

3

TM07 0783 0218

The pump can be installed vertically and horizontally. If you wish to
install a pump horizontally, it must be ordered with support brackets
fitted from factory and a foot-mounted motor.

3a

TM05 7705 1013

Additional support. As the centre of gravity of the pump is relatively
high, we recommend that pumps installed on ships, in areas with risk
of earth quake or in systems which can be moved, are equipped with
an additional support bracket. You can fit the bracket from the motor
stool to the bulkhead of the ship, a rigid wall in a building or to a rigid
part.

4

TM02 0116 3800

To minimise possible noise from the pump, we recommend that you fit
expansion joints on either side of the pump.
Build a foundation and carry out mechanical installation as described
in section 3.1.3 Foundation.
Fit isolating valves on either side of the pump to avoid draining the
system if the pump needs to be removed for cleaning, repair or
replacement.
Always protect the pump against backflow by means of a non-return
valve.

5

TM02 0114 3800

Install the pipes so that air pockets do not occur.

6

TM02 0115 3800

Fit a vacuum valve close to the pump if the installation has one of
these characteristics:

• The outlet pipe slopes downwards away from the pump.

• There is a risk of siphon effect.

• Protection against backflow of unclean liquids is needed.

English (GB)

9

3.1.3 Foundation

We recommend that you install the pump on a
concrete foundation which is heavy enough to
provide permanent and rigid support for the entire
pump. The foundation must be capable of absorbing
any vibration, normal strain or shock. The concrete
foundation must have an absolutely level and even
surface.

Place the pump on the foundation, and fasten it. The
base plate must be supported on the whole area.

The following instruction applies when mounting the
pump in both vertical and horizontal position. Place
the pump on the foundation, and fasten it. See fig.

16.

Fig. 16 Correct installation

Fig. 17 Foundation, vertical mounting

The recommended length and width of the
foundation are shown in fig. 17. Note that for pumps
with motor size below or equal to 30 kW, the length
and width of the foundation must be 200 mm larger
than the base plate.

For pumps with motor size equal to 37 kW or above,
the length and width must always be 1.5 x 1.5 (Lf x
Wf) m.

Fig. 18 Foundation, horizontal mounting

The foundation length and width must always be 200
mm larger than the length and width of the pump.
See fig. 18.

The mass of the foundation must be at least 1.5
times the total mass of the pump. The minimum
height of the foundation (hf) can then be calculated:

The density (δ) of concrete is usually taken as 2200
kg/m

3

.

In installations where noiseless operation is
particularly important, we recommend that you use a
foundation with a mass up to 5 times that of the
pump.

The foundation must be provided with anchor bolts
for fixing the base plate. See fig. 19.

Fig. 19 Bolt in foundation

When the anchor bolts are in position, place the
pump on the foundation. Then align the base plate
using shims, if necessary, so that it is completely
horizontal. See fig. 20.

Fig. 20 Alignment with shims

WARNING

Falling objects

Death or serious personal injury

- Keep the product in a stable and fixed
position before installing it.

- Make sure that the foundation is
suitable for the weight of the product.

3.1.4 Vibration dampening

Elimination of noise and vibrations is best achieved
by means of a concrete foundation, vibration
dampers and expansion joints.

If you use vibration dampers, install them under the
foundation. For pumps with motor size below or
equal to 30 kW, you can use vibration dampers as
shown in fig. 21.

For pumps with motor size equal to 37 kW or above,
you can use a Sylomer

4.2 Shaft seal run-in

The seal faces are lubricated by the pumped liquid,
meaning that there may be a certain amount of
leakage from the shaft seal.

When you start the pump for the first time, or when
you install a new shaft seal, a certain run-in period is
required before the leakage is reduced to an
acceptable level. The time required for this depends
on the operating conditions, that is every time the
operating conditions change, a new run-in period will
be started.

Under normal conditions, the leaking liquid will
evaporate. As a result, no leakage will be detected.

9. Technical data

9.1 Operating conditions

9.1.1 Ambient temperature and altitude

See the instructions for the motor which are supplied
with the pump.

9.1.2 Maximum system pressure and liquid
temperature

The maximum permissible system pressure and
liquid temperature are stated on the nameplate
which is placed on the pump. For identification of the
nameplate data, see section 5.1.1 Nameplate.

9.1.3 Maximum permissible operating pressure
and liquid temperature for the shaft seal

The operating range of a shaft seal depends on the
operating pressure, the liquid temperature and the
type of shaft seal.

The selection charts show which shaft seals are
suitable at a given temperature and a given
pressure.

See figs 26 and 27. The charts apply to clean water.

Shaft seals for ∅22 shaft ends: CR, CRN with
motors up to and including 55 kW

Fig. 26 Maximum permissible operating

pressure and liquid temperature for
pumps with ∅22 shaft seal ( ≤ 55 kW)

Shaft seals for ∅28 (75-110 kW) and ∅36 (132-200
kW) shaft ends

Fig. 27 Maximum permissible operating

pressure and liquid temperature for
pumps with ∅28 shaft seal (75-110 kW)
and ∅36 shaft seal (132-200 kW)

9.1.4 Minimum inlet pressure

Fig. 28 Schematic view of open system with a

CR pump

Calculate the maximum suction lift "H" in m head as
follows:

If the calculated "H" is positive, the pump can
operate at a suction lift of maximum "H" m head.

If the calculated "H" is negative, an inlet pressure of
minimum "H" m head is required. There must be a
pressure equal to the calculated "H" during
operation.

H = Pb x 10.2 - NPSH - Hf - Hv

Pb = Barometric pressure in bar.

Barometric pressure can be set to 1 bar.
In closed systems, Pb indicates the system

pressure in bar.

NPSH = Net Positive Suction Head in m head, to be

read from the NPSH curve on page 24 at
the highest flow the pump will be delivering.

Hf = Friction loss in the inlet pipe in m head at

the highest flow the pump will be delivering.

Hv = Vapour pressure in m head. See Fig. E on

page 28.

tm = Liquid temperature.

/h.
NPSH (from page 24): 1.1 m head.
Hf = 3.0 m head.
Liquid temperature: +60 °C.
Hv (from Fig. E on page 28): 2.1 m head.
H = Pb x 10.2 - NPSH - Hf - Hv - Hs

[m head].
H = 1 x 10.2 - 1.1 - 3.0 - 2.1 - 0.5 = 3.5 m head.
This means that the pump can operate at a suction

lift of maximum 3.5 m head.
Pressure in bar: 3.5 x 0.0981 = 0.343 bar.
Pressure in kPa: 3.5 x 9.81 = 34.3 kPa.

9.1.5 Maximum permissible inlet pressure

The table on page 25 states the maximum
permissible inlet pressure for vertically mounted
pumps. However, the actual inlet pressure + the
maximum pump pressure at no flow must always be
lower than the maximum permissible system
pressure which is stated on the pump nameplate. For
identification of the nameplate data, see section

5.1.1 Nameplate.

The pumps are pressure-tested at a pressure of 1.5
times the maximum permissible system pressure.

9.1.6 Minimum flow rate

Due to the risk of overheating, do not use the pump
at flows below the minimum flow rate.

The curves below show the minimum flow rate as a
percentage of the rated flow rate in relation to the
liquid temperature.

- - - - = air-cooled top.
