8

Grundfos BMS, BMST and BMSX booster systems are designed
for desalination of seawater or brackish water in reverse osmosis
systems, the so-called SWRO systems (SWRO = Sea Water
Reverse Osmosis). The design of the systems ensure high
energy recovery.

2.1 Delivery and handling

2.1.1 Delivery

The pumps are supplied from the factory in proper packing in
which they should remain until installation.

2.1.2 Frost protection

If the pumps have to be stored, the location must be frost-free.

it may result in personal injury.

If these safety instructions are not observed,
it may result in malfunction or damage to the
equipment.

Warnin g
The sound pressure level is so high that hearing

protection must be used.

Notes or instructions that make the job easier
and ensure safe operation.

During delivery and storage, the pumps must
never be preserved with glycerine or similar
liquids which are aggressive to the pump
materials.

English (GB)

Warning
Prior to installation, read these installation and

operating instructions. Installation and operation
must comply with local regulations and accepted
codes of good practice.

2.3 Commissioning

Commissioning of BMSX booster systems must be carried out by
certified Grundfos employees to ensure long and trouble-free
operation.

If this requirement is not met, the warranty will be
invalidated.

Commissioning includes onsite training of the people who will be
responsible for maintaining and monitoring the system.

2.4 Pumped liquids

Thin, non-explosive liquids, not containing solid particles or
fibres. The liquid must not chemically attack the pump materials.
In case of doubt, contact Grundfos.

The pumps must never operate with water/liquid containing
substances which would remove the surface tension, e.g. soap.
If this type of detergent is used to clean the system, the water/
liquid must be led around the pumps via a bypass.

Warnin g
The pumps must not be used for pumping

flammable or combustible liquids such as diesel
oil, petrol or similar liquids.

2.5 Filtration

BMS hs, BMST: The raw water must be filtered to maximum
30 microns.

BMSX: The raw water must be filtered to maximum 10 microns.

2.7 Foundation

The foundation must be constructed to safely support the booster
system or pump(s) under all conditions. The pump and motor
must be installed at the same level.

The foundation must be strong enough to support the weight of
the both units.

2.7.1 Vibration dampening

The vibration dampeners supplied with the BMS hs pump must be
used.

3. Before installation

Caution

1. Check that the pump has not been damaged during
transportation.

2. Check that the type designation corresponds to the order.
See the pump nameplate.

3. Compare the motor voltage and frequency details on the
motor and frequency converter nameplates with the power
supply available.

4.1.1 Location

To ensure sufficient cooling of the motor, a free space of minimum
100 mm behind the motor (NDE) is required.

4.1.2 Lifting and handling the motor

Warning
Observe local regulations concerning limits for

manual lifting or handling.

Use all lifting eyes when lifting the motor, and lower it down
slowly.

Warning
Use all lifting eyes on the motor, and make sure

that the crane is suitable for the job. Use certified
and approved lifting equipment. See nameplate.

TM05 9569 4113

If these instructions are not followed, there is a
risk of warping or crushing some equipment
such as the terminal box, cover or drip cover.

4.1.3 Motor installation

Caution

Caution

English (GB)

Use vibration dampers.

The motor must be level. If there is a gap between the foundation
and motor, use a spirit level, a feeler gauge and shims to level the
motor. Then secure the motor by means of suitable bolts
depending on the foundation.

Direction of rotation

Warning
The electrical installation should be carried out

by an authorised person in accordance with local
regulations.

Connect the power supply (see section 5. Electrical installation)
and check the direction of rotation. The direction of rotation must
correspond to the direction under normal operation. See the
installation and operating instructions for the motor.

4.1.4 Lifting and handling the pump

Hoist the pump into place, and lower it down slowly.

4.1.5 Alignment of m otor and pump

Align the motor and pump before you tighten the bolts. To ensure
correct installation, follow this procedure:

Step Description Picture

Fit all four bolts for
motor and pump
connection.

1

Do not tighten the
bolts yet.

Adjust the gap by
means of a feeler
gauge or similar tool.

2

Tighten one bolt by
hand.

Adjust the gap 180 °
opposite the bolt you
just tightened.

3

Do not tighten the
bolt. Move the pump
to adjust the gap.

4.1.7 Flushing the system

To avoid impurities in the pump, flush the pipes
before you connect the pump inlet and discharge
pipes.

4.1.8 Pipe connection

Both the inlet and the discharge pipe are fitted with clamp liners
for Victaulic couplings and must be supported close to the end of
the pipe.

TM05 9347 3613

English (GB)

In order to facilitate service of the pump and motor, it is important
that the delivered service connector is built into the system.

1. Fit the two rubber parts.

2. Install the service connector.

4.2 BMST system

A BMST system is built by using a BMS hs as primary pump and
a BMT as secondary pump. The BMT pump is driven by the high­pressure concentrate from the membrane and used as feed pump
for the primary BMS hs pump.

Fig. 9 Position of rubber parts

3. Move the two rubber parts over the service connector.

Fig. 10 Position of service connector and rubber parts

4. Fit the Victaulic couplings and tighten the bolts to 33 Nm.

4.2.1 BMS hs pump installation

See section 4.1 BMS hs pump.

4.2.2 Lifting and handling the BMT pump

1. Hoist the pump into place, and lower it down slowly.

2. Install and secure the pump.

3. Support the pump close to the turbine, using the bracket
behind the turbine housing.

4. Use a clamp or similar device at the other end. See the
example in fig. 12.

4.2.3 BMT pump installation

Use vibration dampers.

The BMT pump must be level. If there is a gap between the
foundation/frame and the BMT pump, use a spirit level, a feeler
gauge and shims to level the pump. Then secure the pump by
means of suitable bolts depending on the foundation/frame.

4.2.4 Flushing the system
