For easy deaeration of the pump:

● Install a ball valve (11) with bypass line (back to the dosing tank)
immediately behind the pressure valve

In case of long pressure lines:

● Install a check-back valve (12) into the dosing line.

● Keep the suction line as short as possible, avoid a tangled suction

line

• If necessary, use swept bends instead of elbows.

● Always lay the suction line rising to the suction valve of the dosing
pump.

• Avoid loops which cause air bubbles.

● For non-degassing media with viscosity similar to water, the pump
can be mounted onto the tank (observe the admissible suction
height). Preferably flooded suction.

For dosing media which tend to sedimentation:

● Install a suction line with filter (13) in a way ensuring that the suction

● In dosing systems that require a long suction line:
Provide a properly dimensioned pulsation damper (4) directly in front of the

suction valve of the dosing pump.

● Note for pressure side installation:
to protect the piping use pulsations damper (8) for rigid piping longer than
3m and tubing longer than 5m.

● With open outflow of the dosing medium or a counterpressure below 1 bar:
Install a pressure retention valve (7) directly in front of the outlet or the
injection unit.
A positive pressure difference of at least 1 bar has to exist between the
counterpressure at the injection point and the pressure of the dosing medi­um at the suction valve of the dosing pump. If this cannot be guaranteed:

• Install a pressure retention valve (7) in the pressure line

4.2 Transport and Storage

● Handle with care, do not throw!
❏ Dry and cool storage place.
❏ Take heed of upright position of the dosing pump when storing it, so that

gear grease can not leak out.

CAUTION Observe permissible storing temperature!

4.3 Mounting

● Mount the pump horizontally on the tank or on a console.

4.4 Connecting the Suction and Pressure Lines

WARNING All lines must be stress-free!

!

● Depending on the material of the connection flanges (1) (mating flanges)

• Pipe and flange made of 1.4571 steel:

Weld the pipe in the blanking flange

• Pipe and flange made of PP:

Weld the pipe in the flange sleeve

• Pipe and flange made of PVC:

Adhere the pipe in the flange sleeve

Only use the prescribed line types!

❏ The internal diameter of the lines, adapters and connectors should not be

smaller than DN 65; if necessary, use bends instead of elbows.

❏ The suction lines must be designed such that cavitation is avoided.

IMPORTANT:

● Pulsation dampers should be fitted on both the suction and pressure
sides.

NOTE A positive pressure difference of 10 m water gauge is

required for correct operation of the dosing pump. If the
total of the back-pressure and the static difference in
height between the suction valve and the dosing point is
less than 10 m water gauge, a pressure maintenance
valve must be installed directly upstream of the dosing
point.

19V3.0

DMX model 227

● Connect suction line to suction valve (A).

• Install the suction line in the solution tank such that the foot valve
remains approx. 10 cm above the bottom of the tank.

● Connect pressure line to pressure valve (B).

IMPORTANT:

● To protect the pump from excessively high pressures:

fit an appropriate overflow valve in the pressure line.

● Make sure that the valves are seated correctly
– position of valve disk (C)!

Do not switch on the mains until the pump should be
started.

A motor protector, adjusted to nominal motor current,
must be installed by the customer.

For use with a frequency converter the jumpers in the
clamp box have to be set according to the converter
voltage.
In the state of delivery, the jumpers of 3-phase motors
are set for star connection.

5.1 Inspections before Commissioning

● Check the tightness of all connections. If necessary, retighten.

● Check the correctness of all electrical connections.

● Check if the voltage indicated on the type plate corresponds with the local

voltage!

5.2 Commissioning

CAUTION After initial start-up and after each diaphragm

Fill with gear oil

The pump has been tested in the factory, and the oil drained prior to shipping.
Before using, fill with the supplied special oil as follows:

● Switch off the pump.

● Unscrew the venting screw with oil dipstick.

● Slowly pour the supplied gear oil into the opening of the venting screw until

it reaches the mark on the dipstick.

- Gear oil for single pumps: 5.0 l

- Gear oil for dual pumps: 7.5 l

● Switch of the pump after approx. 10 minutes, check the oil level, and add

more if necessary.

● Refit the oil dipstick.

6.2 Principle of function

❏ Oscillating positive displacement pump with electric drive, mechanical

diaphragm deflection, and constant stroke length.

❏ Following reduction of the motor speed by a worm gear, the rotation of the

drive is converted into the suction and compression movement of the
diaphragm by means of an eccentric and tappet. A defined volume (stroke
volume) of the dosed medium is thus sucked into the dosing head via the
suction valve, and displaced into the dosing line by the pressure valve.

❏ The dosing rate can be adjusted in the range 1:10 if a frequency converter

is fitted.

6.3 Switching on / off

6.3.1 Switching on

● Switch on the mains power.

6.3.2 Switching off

Refer to Operation Manual of the frequency converter!

WARNING Observe operating instructions of the manufacturer!

!

Settings in conjunction with GRUNDFOS dosing pumps

Please observe especially the following parameters of the frequency converter:
❏ P013 (maximum motor frequency):

Set to maximum 100 Hz.
Due to this setting, the maximum stroke frequency of the pump cannot be
exceeded.

❏ P086 (motor current limit):

Do not change the default setting (150%).
The motor is protected by a PTC resistor. Therefore, this parameter is not
necessary.

❏ P081 - P 085 (motor data)

Please set this parameters to the values indicated on the type plate of the
motor.
