1 Safety relevant instructions for ProMinent®metering
pumps
Safety precautions and important operating instructions are divided into classes and provided
with symbols. Please familiarise yourself with the following designations and symbols.
DANGER:
There is a danger of injury or to life!
WARNING:
There is a danger of injury or the equipment can be seriously damaged!
CAUTION:
The situation demands increased awareness!
NOTE:
Information which is to be noted!
WARNING:
This equipment may only be used for its intended purpose.
1.1 General notes
WARNING:
• Assembly of ProMinent®metering pumps with foreign parts which are not tested or
recommended by ProMinent is not permissible and can lead to injury to persons or
damage for which no responsibility is accepted!
• Pumps must be accessible for operating and servicing at all times. Accesses must not
be obstructed or blocked!
• For servicing and repair work where dangerous or unknown dosing media are being
used, first empty and flush out the liquid end! Observe the safety data sheets for the
dosing liquid!
• When metering dangerous or unknown liquids those working on the liquid ends must
wear protective clothing (goggles, gloves)!
1.2 Notes for installation, commissioning and operation
WARNING:
• The metering pump may still contain residual water in the liquid end from testing in the
factory.
• In the case of media which must not come into contact with water, the liquid end must
be cleared of all water before commissioning. To do this rotate the pump 180° and
empty the liquid end and then flush from above through the intake connection using a
suitable medium.
• Do not connect mains voltage to the control cable!
• When operating the metering pump against a closed isolator at the pressure end, the
backpressure can reach several times the maximum permissible backpressure.
This can cause the delivery line to burst!
To avoid this, a pressure relief valve is recommended which limits the backpressure!
CAUTION:
• Design the pressure lines so that pressure peaks on the discharge stroke do not exceed the
maximum permissible pressure (fit a pressure relief valve if necessary)!
• Adjustments to the stroke length should only be carried out with the pump running!

NOTE:
• The pump shall be secured in such a way that no vibration can occur!
The valves of the liquid end must always be vertical to ensure correct operation!
• Intake and delivery pipes must always be arranged such that strain-free connection to the
liquid end is guaranteed!
Pipes shall be secured in such a way that no vibration can occur!
• Use only the locking rings and hose fittings designed for the particular hose diameter and also
use original hoses with the specified hose dimensions and wall thickness, otherwise the
security of the connection is not guaranteed!
Reductions in hose sizes are to be avoided!
The permissible pressure stress of the hoses is to be observed.
• When dosing extremely aggressive or dangerous media an arrangement which relieves back
into the tank is advisable!
Moreover, an shut-off valve should be fitted on the pressure and suction sides!
1.3 Notes on servicing and repair
WARNING:
• Metering pumps and their peripherals may only be serviced by expert and authorised
persons!
• When carrying out servicing or repairs where dangerous or unknown media are used,
always flush the liquid end first!
• When metering dangerous or unknown liquids, those working on the liquid end must
wear protective clothing (goggles, gloves)!
• The pressure in the metering pipe must first be released before working on the pump.
Always empty and flush the liquid end!
Observe the safety data sheets for the metering liquid!
DANGER:
• Isolate the supply cable or withdraw the mains plug before opening the pump.
If the optional relay is fitted, also isolate this!
Check for freedom from voltage!
Always secure the pump against unauthorised restarting during repair work!
• Pumps which are used for dosing radioactive media must not be shipped!
NOTE:
• Pumps must only be returned for repair in a clean condition and with the liquid end flushed
out!

2 Product Description
CAUTION:
Use in accordance with regulations
The Vario is a diaphragm metering pump for dosing liquid media. Example of use: quantity-
proportional dosing of chlorine bleaching solution to drinking water. Control is achieved by means
of a contact water meter.
Incorrect use
The pump is not designed to dose gaseous media or solids. When dosing chemicals the
resistance of the materials shall be taken into account. Refer to resistance list.
The pump is not suitable for use in explosion-proof areas.
2.1 Marking/Identification of pump type
Each Vario metering pump shall be provided with an identification plate on the side of the foot.
The identity code and serial number shall be given in addition to the normal technical data.

Product Description
2.2 Construction and functional description of drive unit
The ProMinent®Vario is an oscillating displacement metering pump whose stroke length can be
adjusted in steps of 1%. It is driven by a special custom built single phase AC motor or a
standard three phase motor (1). Its drive rotation is reduced by the worm gearing (2) and
transmitted via the eccentric roller (3) to the connecting rod (4) and therefore changed to an
oscillating motion. A powerful return spring (5) holds the connecting rod against the eccentric
roller to provide a return stroke. The length of the stroke is adjusted by using the stroke
adjustment knob (6) and shaft (7) to limit the return stroke. The stroke is transmitted directly to
the piston. In conjunction with the valves, this generates the pressure or vacuum in the liquid end
which is necessary for delivery. The delivery flow is pulsating.
2.3 Construction and functional description of
diaphragm delivery unit
The heart of the delivery unit is the DEVELOPAN®metering diaphragm (4). It hermetically seals
the delivery chamber of the liquid end (2) and effects the displacement in the liquid end (2). The
end washer (5) of chemically-resistant plastic separates the drive housing from the delivery part
and protects the drive from corrosion in the event rupture of the diaphragm. The suction valve (1)
and pressure valve (3) which are of identical construction, operate in conjunction with movement
of the diaphragm to provide the delivery operation. The valve balls can be spring-loaded for
metering viscous media.
The connecting dimensions of valves and liquid ends which are the same size but of different
material are the same. The parts can be interchanged as required. An integrated bypass-/bleed
valve may be optionally installed in the PVT version (see page 9).

CAUTION:
• Knob Item 139 must be turned in clockwise direction as far as it will go „close“.
• The bypass line must always be closed and must be routed back into the supply tank.
Connection via hose connection Item 128.
• Minimal overflow can occur in the bypass line when the valve operates close to the
overpressure function.
The bleeder function is achieved by turning knob Item 139 in counterclockwise direction as far as
it will go „open“: Priming aid for starting up pump against pressure. The force of spring Item 132
relieves ball Item 130 which is controlled by the lower spring force of bleeder spring Item 133.
CAUTION:
• Once the pump has primed, turn knob Item 139 in clockwise direction as far as it will go
„close“! The pump can now be placed into operation.
Technicaldata
Corresponding to the type of pump, overflow valves are available for pressure stages pnom 3.5/
4.5/5.5/6.5/8.5/10 bar with (1.05...1.4) xpnom opening pressure.

2.3.1 IntegratedOverflowValvewithBleederFunction
Task
The task of the overflow valve is to protect the motor and gear unit against impermissible
overpressure caused by the metering pump.
This function is produced by a spring-loaded ball.
A pressure relief mechanism for the bleeder function is provided.
DesignandFunctionalDescription
Initially, the overflow valve illustrated unter Item 102 operates as a simple directly control safety
valve. As soon as the pressure set with spring Item 132 is exceeded, the effective pressure raises
ball Item 130. The liquid then flows off into the tank via hose connection Item 128.

Useforintendedpurpose/Usenotforintendedpurpose
Useforintendedpurpose
To protect the motor and gear unit against impermissible overpressure caused by the metering
pump.
If the pump is the only pressure generator in the system, the overflow valve will also protect the
system automatically.
CAUTION:
• Only for liquids with a viscosity of up to 100 mPa · s
• On pumps with a 1 ph AC motor, the motor is protected by an integrated thermal cutout.
• The ceramic ball and ball seat of the overflow valve are wearing parts. Slight leakage can
occur at the safety valve after a prolonged period of operation. The ball and ball seat should
be replaced if leaks occur.
• The bypass line must always be connected and must be routed back into the supply tank.
• Refer to the installation notes in the operating instructions for „Motor Driven Metering
Pumps“.
Usenotforintendedpurpose
To protect the system from impermissible overpressure which has other causes than the
pressure generated by the metering pump.
The pump must not be operated without the bypass line connected.
Connection of the bypass line in the intake line is not permitted as this would impair the
effectiveness of the bleeder function.
DANGER:
When carrying out maintenance work on the overcurrent valve, pay attention to the
tensioning state of the pressure spring Item 132! Wear safety goggles!
