4 Installation

4.1 Installation Information

Picture of optimal installation:

1 Dosing tank 502

2 Electric agitator 509

3 Extraction device 521

4 Suction pulsation damper 516

5 Dosing pump

6 Overflow valve 525

7 Pressure retention valve 525

8 Pulsation damper 517

9 Measuring glass

10 Injection unit 522

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

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

- p

1 bar

● Note for pressure side installation:

to protect the piping use pulsations damper (8) for rigid piping longer than

3m and tubing longer than 5m.

● 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.

● For outgassing and viscous media: flooded suction

● To protect the dosing pump and the pressure line agains: excessive

development of pressure: Install an overflow valve (6) in the pressure line.

10 Injection unit

● 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 medi-

um at the suction valve of the dosing pump. If this cannot be guaranteed:

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

To avoid the siphon effect:

● Install a pressure retention valve in the dosing line and, if necessary, a

solenoid valve (14) in the suction 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!

Only use the prescribed line types!

● 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

❏ 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.

20 15.720023-V3.0

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)!

4.5 Electrical Connections

WARNING Prior to the mains connection check if the voltage

indicated on the type plate corresponds with the local

voltage!

Switch off mains before connecting!

No changes at the mains cable and the mains plug may

be done!

NOTE The pump is being switched by switching the mains

voltage.

Do not switch on the mains until the pump should be

started.

4.5.1 Connect the motor

● Connect the motor according to the terminal connection diagram (stamped

in the clamp box).

CAUTION Observe the sense of rotation!

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.
