English (GB)

2.2.4 Installation depths

2.2.5 Level of pumped liquid

The lowest stop level is the level where the pump

starts to suck air.

The A models have an integrated level control

system. A stands for "Automatic". This system will

stop the pump when the stop level is reached. Model

DW.50.08.A has an external float switch.

2.2.6 Operation

The pumps are designed for continuous operation.

The A models have to be switched over to "C" for

continuous operation.

For model DW.50.08.A, the float switch must be tied

up. See fig. 1.

Fig. 1 DW.50.08.A

2.3 Sound pressure level

The sound pressure level of the pump is lower than

the limiting values stated in the EC Council Directive

2006/42//EC relating to machinery.

3. Safety

4. Transportation and storage

The pump may be transported and stored in a

vertical or horizontal position. Make sure that it

cannot roll or fall over.

Always lift the pump by its carrying handle, never by

the motor cable or the hose/pipe.

If the staff do not have the necessary knowledge

about handling and lifting the pump they must be

trained and instructed accordingly.

For long periods of storage, the pump must be

protected against moisture and heat.

After a long period of storage, the pump should be

inspected before it is put into operation. Make sure

that the impeller can rotate freely. Pay special

attention to the shaft seals and the cable entry.

5. Installation

Installation dimensions, see page 120.

Prior to installation, check the oil level in the oil

chamber, see section 8. Maintenance and service.

The DW pumps have pump housing for free-standing

installation.

The pump can be installed with a hose/pipe.

In order to facilitate service of the pump, fit a flexible

union or coupling to the discharge line for easy

separation.

If a hose is used, make sure that the hose does not

buckle and that the inside diameter of the hose

matches that of the discharge port.

If the pump is installed in muddy conditions or on

uneven ground, it is recommended to support the

pump on bricks.

Lower the pump into the liquid.

Warning

Pump installation in wells must be carried

out by specially trained persons.

English (GB)

Model A:

The A models have an integrated level control

system.

By means of two electrodes, the level control system

measures the water level in the water level

compartment. The short electrode starts the pump

and the long one stops the pump.

When the pump has drained the pit/sump, the rubber

valve, situated next to the electrodes on top of the

motor housing, will draw in air to drain the pump.

When the A models are used for automatic operation

in deep pits/sumps, a non-return valve must be

mounted immediately after the discharge port to

prevent backflow and thus intermittent operation

when the pit/sump has been drained. See fig. 2.

Fig. 2 Model A

6. Electrical connection

The electrical connection of the pump should be

carried out in accordance with local regulations.

The operating voltage and frequency are marked on

the nameplate. Voltage tolerance: ± 10 % of the

voltage stated on the nameplate. Make sure that the

motor is suitable for the electricity supply available at

the installation site.

6.1 Motor protection

All Grundfos DW pumps have a thermal switch built

into the stator windings.

All single-phase Grundfos DW pumps are supplied

with an operating capacitor.

For capacitor sizes, see the table below:

6.2 Frequency converter operation

The DW pumps with integrated motor starter should

not be connected to a frequency converter, as this

may result in damage to the motor.

Frequency converter operation will often expose the

motor insulation system to a heavier load and cause

the motor to be more noisy than usual due to eddy

currents caused by voltage peaks.

In addition, large motors driven via a frequency

converter will be loaded by bearing currents.

TM01 3433 3998

Warning

Connect the pump to an external mains

switch placed close to the pump and to a

motor-protective circuit breaker.

Make sure you can lock the mains switch

in OFF position (isolated). Type and

requirements as specified in EN 60204-1,

5.3.2.

7. Startup

When the electrical connection has been carried out,

the pump is ready for operation.

Submerge the pump into the liquid to be pumped and

start it.

The valve for the level control system will

automatically vent the pump. Therefore, there will be

no problems with air in the pump.

7.1 Direction of rotation

All single-phase pumps are factory-set to the

correct direction of rotation.

Before starting up three-phase pumps, check the

direction of rotation. The direction of rotation should

be clockwise.

When starting up, the pump will jerk in the opposite

direction to the direction of rotation (the arrow on the

top cover indicates the direction of the jerk). If the

direction of rotation is wrong, interchange two of the

three phases of the electricity supply.

8. Maintenance and service

Before carrying out maintenance and service, make

sure that the pump has been thoroughly flushed with

clean water. Rinse the pump parts in water after

dismantling.

Pumps running normal operation should be

inspected at least once a year. If the pumped liquid is

very muddy or sandy, inspect the pump at shorter

intervals.

When the pump is new or after replacement of the

shaft seals, check the oil level after one week of

operation.

For long and trouble-free operation of the pump the

following points should be checked regularly:

•Power consumption

•Oil level and oil condition

The oil becomes greyish white like milk if it

contains water. This may be the result of a

defective shaft seal. The oil should be replaced

after 3000 hours of operation (DW.50.08, 1000

hours).

Use Shell Ondina X420.

Note: Used oil must be disposed of in

accordance with local regulations.

The following table states how much oil the DW

pumps must have in the oil chamber:

* Filled with grease (Klüber Synteso Proba 330).

Warning

Before starting work on the pump, make

sure that the electricity supply has been

switched off and that it cannot be

accidentally switched on. Furthermore,

all rotating parts must have stopped

moving.

Warning

When unscrewing the inspection screw of

the oil chamber, please note that

pressure may have built up in the

chamber. Do not remove the screw until

the pressure has been fully relieved.
