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.

V6.0

● 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.

p

● 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

valve remains several centimetres a bove the botton of the tank.

● 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 with 4 screws M8 on the tank or on a console.

● Replace the screw plugs by the attached venting screws.

4.4 Connecting the Suction and Pressure Lines

WARNING All lines must be stress-free!

!

Only use the prescribed line types!

C

A: Suction valve C: Pipe connection
B: Discharge valve D: Tube connection (only DN20)

● Connect the suction line to the suction valve (A).

• The foot valve must keep a distance of ca. 10 cm to the bottom of the
container.

● Connect the pressure line to the pressure valve (B).

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

voltage.
In the state of delivery, the jumpers of 3-phase motors
are set for star connection.

5 Commissioning

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

● Open the shut-off valves (15, 16, if installed) both at the suction and
pressure side.

● Open the deaeration valve (17, if installed) of the dosing line, or remove
pressure on the pressure side so that the medium is able to issue without
counterpressure.

● Switch on mains voltage.

● Set the stroke length adjustment knob to 100%.

Keep the dosing pump in operation until bubble-free medium comes out of the
deaeration valve or the dosing line.

● Close the deaeration valve (17, if installed).

The pump is now ready for operation.

Principle of function

❏ Reciprocating displacement pump with electric motor and mechanical

diaphragm guide

.

❏ The rotation of the motor is transformed into the reciprocating movement of

the dosing diaphragm by the eccentric and the tappet.

❏ Adjustment of the dosing flow is possible by adjusting the stroke length of

the tappet.

running!
Danger of damages.

The zero point (no dosing) of the dosing pump is adjusted in the works at a
counterpressure of 3 bar (see dosing curves).

If the operational counterpressure at the injection point is considerably above or
below this value, it is advisable to readjust the zero point to obtain more precise
values of the dosing output.

● Install a graduated tube at the suction valve.
If this is not present:

• insert the suction line into a graduated measuring jug.

● Start the dosing pump and adjust the dosing flow to 15%.
For pumps with tank empty indication:

• Remove the plug of the tank empty indication.

● Completely unscrew the locking screw (A) on the stroke length adjustment
knob (1) using a screwdriver.

● Turn the adjustment knob slowly clockwise until the dosage stops in the
measuring jug or tube.

● Remove the plug with a small screw driver without changing the position of
the adjustment knob and unscrew the cheese head screw together with the
flat spiral spring.

● Fit the adjustment knob on the adjusting spindle so that the zero line on the
scale and the mark on the adjustment knob coincide.

● Screw in the cheese head screw and the spiral spring until the spring is
preloaded but does not block. Even when adjusted to 100% the spring of the
adjustment knob must still remain preloaded.

● Screw in the locking screw (A) again using a screwdriver, and tighten gently.

8.1 Function

8.2 Permissible Media

!

8.3 Connections

DMX model 226 en

The integral overflow valve (option) protects the complete pressure side of the
dosing line system from an impermissibly high buildup of pressure.

The valve opens if the pressure rises above its set opening pressure, and the dosing
medium can return to the solution tank.

In contrast to series-connected overflow valves, the integral valve also provides
pump protection if the pressure valve is contaminated or blocked.

WARNING Dosing heads with integral overflow valve must not be

used for abrasive or crystallizing media.

● Connect suction line to suction valve (A).

● Connect pressure line to pressure valve (B).

● Connect overflow line to overflow valve (C) and allow to flow by gravity into

8.4 Setting of Opening Pressure

8.4.1 General

!

!

!

The opening pressure can only be set if a manometer is installed in the system
between the pump and the next shut-off valve or pressure retention valve.

WARNING Settings on the overflow valve must only be carried out

by authorized specialists!

The opening pressure of the overflow valve is set in the factory to the maximum
pump back-pressure specified in the technical data. The opening pressure during
operation depends on various factors, e.g. the flow, the stroke frequency of the
pump, or the back-pressure. If an exact setting is required, the overflow valve must
be adapted to the local conditions.

The opening pressure must only be set to values below the maximum permissible
operating pressure.

WARNING Danger of injury! Never set the opening pressure

higher than the maximum permissible operating
pressure of the dosing system and dosing pump.

WARNING When dosing dangerous media, always refer to the

corresponding safety data sheets!
Wear protective clothing (goggles, gloves) when
working on the connections and lines!

8.4.2 Setting Instructions for Opening Pressure

Proceed as follows if the factory-set pressure is to be changed:

With the pump running

● Remove the cap from the top part of the overflow valve.

● Close the shut-off valve downstream of the manometer.

● When overflowing of the dosing medium is heard, read the current opening

pressure on the manometer.

● Using pointed pliers, rotate

- in the clockwise direction to increase the pressure or

- in the counterclockwise direction to reduce the pressure

until the desired opening pressure is set.

● Open the shut-off valve downstream of the manometer.

● Attach the cap again.
