Notes on safety of ProMinent®metering pumps
1 Notes on safety of ProMinent®metering pumps
Notes on safety and important operating notes are divided into classes accompanied with
pictograms. Please familiarize yourself with the following definitions and pictograms.
DANGER
Danger to life or risk of serious injury!
WARNING
Danger of injury or serious damage to the device!
NOTICE
These situations require complete attention!
IMPORTANT
Information which must be followed!
1.1 General notes
WARNING
•The equipment/devices may only be used for their intended purpose.
•ProMinent®metering pumps must not be assembled with parts which are not
tested and recommended by ProMinent otherwise this can lead to injury to
persons and damage to property for which no liability will be accepted!
•Pumps must be accessible at all times to facilitate operation and maintenance.
Access points must not be obstructed or blocked!
•Before carrying out any maintenance and repair work always drain off and
flush out the liquid end first if hazardous or unknown metered media are used!
•When metering hazardous or unknown liquids, always wear safety clothing
(safety goggles, gloves, ...) when working on the liquid end!
•You must observe the guidelines in this operating instructions manual and the
”General operating instructions manual for ProMinent®motor-driven metering
pumps and hydraulic accessoires”on assembly, installation and maintenance!
1.2 Notes on installation, start-up and operation
WARNING
•The metering pump can contain water residue in the liquid end as the result of
testing at the factory!
If handling media which must not come in contact with water, all traces of
water must be removed from the liquid end before start-up! For this purpose,
turn the pump through 180˚and drain off the liquid end then flush with a
suitable medium from above via the intake connection!
•Do not connect mains voltage to the control cable!
•When operating the metering pump against a closed shut-off element on the
pressure side or in the event of pressure peaks during the metering stroke, the
system pressure can reach a multiple of the maximum permissible operating
pressure that can consequently cause the pressure line to burst!
•To avoid this situation, an overflow is recommended for the purpose of limiting
the maximum permissible operating pressure of the pump or system.
•Do not connect a metal bypass line to the overflow valve on the PVT delivery
unit! This could cause cracks in the delivery unit!
•The bearing cover (1) must be fitted when in operation.
The equipment will not otherwise comply with IP 55 and the bearing will not be
adequately secured!
•The design cover (2) must be fitted when in operation.
Equipment will not otherwise comply with IP 55.

NOTICE
•Set stroke length only with pump in operation!
IMPORTANT
•The pump must be secured in such a way that no vibrations can occur! The valves
of the liquid end must always be positioned vertically in order to ensure trouble-free
operation!
•The intake and delivery lines must always be arranged such as to ensure connection
at the liquid end free of mechanical stress!
The lines must be secured such that no vibrations can occur!
•Only use the clamping rings and hose sockets intended for the relevant hose
diameter as well as original hoses with the specified hose dimensions and wall
thickness otherwise the stability and durability of the connection will not be
guaranteed!
Avoid reducing hose sizes!
Observe the permissible pressure of the hoses!
•A vent with return to the supply tank is advisable when metering extremely
aggressive or hazardous media!
In addition, a shut-off valve should be provided on the delivery or intake side!
1.3 Notes on maintenance and repair
WARNING
•Only specially trained and authorized persons are permitted to carry out
maintenance on metering pumps and their periphery!
•If hazardous or unknown metering media are used, always flush out the liquid
end first before carrying out any maintenance and repair work!
•When metering hazardous or unknown liquids, always wear safety clothing
(safety goggles, gloves) when working on the liquid end!
•Always depressurize the delivery line first before carrying out any work on the
pump!
Always discharge and flush liquid end!
Observe safety data sheets for metered liquid!
DANGER
•Disconnect power plug or power supply line before opening the plug!
Isolate relay option if applicable!
Check to ensure power is disconnected!
Secure pump while carrying out repairs to ensure it cannot be switched on
unintentionally!
•Pumps for metering radioactive media must not be shipped through standard
channels!
IMPORTANT
The metering pump must be in a cleaned condition with the liquid end flushed if
returned for repair!

WARNING
Use for intended purpose
•The pump is designed as a liquid medium metering pump; it serves the purpose of
metering liquid medium within the specified line system!
•Operate the pump only within the conditions described in the technical data!
•General restrictions with regard to viscosity limits, chemical resistance and density must
be observed (refer to ProMinent®chemical resistance list (catalogue or homepage))!
•All other applications or conversion are prohibited!
•The pump is not designed to meter gaseous media as well as solids.
•The pump is not suitable for metering combustible liquids!
•Only specifically trained and authorized personnel are permitted to operate the pump!
2.1 Identification of pump type
The identity code and serial number are given in addition to the standard technical specifications.
These two numbers must always be quoted when making any enquiries as they enable distinct
identification of the type of metering pump.
2.2 Design/Functional description
2.2.1 Functional description, drive
The ProMinent®Sigma/ 1 diaphragm-type metering pump is an oscillatory displacement pump
with the stroke length adjustable in steps of 1%. It is driven by electric motor (1). The rotary drive
of the electric motor is stepped down by worm gear and transmitted via the eccentric roller (3) to
the push rod (4) connected to fork (8) and converted into oscillatory movement. Return spring (5)
presses the fork with push rod positively against the eccentric roller thus producing the return
stroke. The stroke is adjusted by means of stroke adjustment knob (6) and spindle (7) by limiting
the return stroke. Stroke movement is transmitted directly to the displacement diaphragm.
Interacting with the valves, this diaphragm produces the overpressure and vacuum in the liquid
end necessary for delivery. Flow is pulsating.
In the basic type, the electric motor is normally a 3-ph extended-range AC motor (refer to
Section 3 for other options).

IMPORTANT
A large stroke length and low metering frequency should be selected for very viscous
media!
A shorter stroke length and high frequency should be selected to achieve good mixing
properties!
2.2.2 Stroke movement
Set stroke length dependent on the required delivery capacity.

IMPORTANT
•The metering output of S1Ba at 60 Hz is approximately 1.2 times the metering
output of S1Ba at 50 Hz.
•For pump types S1Ca, the output data at 60 Hz apply (for S1Ca, however, only 200
strokes/min. are possible).

2.2.4 Functional description, delivery unit
The heart of the delivery unit is the DEVELOPAN®metering diaphragm (2). It hermetically seals
the delivery chamber of liquid end (4) and produces a displacement in the liquid end. The end
disc (5) made of chemically resistant plastic together with safety diaphragm (13) separates the
drive housing from the delivery unit and protects the drive from corrosion in the event of the
diaphragm failing. Delivery is based on the interaction between intake valve (1) and head valve (3)
of the same design together with the diaphragm movement. The valve balls can be supported
with springs for metering viscous media.
The connection dimensions of valves and liquid ends of the same size but with different materials
are identical. These parts can be interchanged as required.
Materials and dimensions are specified in Section 3, Technical data.

2.2.5 Integrated overflow valve with bleeder function
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.
Design and functional description
(refer to Fig. No. 7 and 8)
Initially, the overflow valve illustrated under 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.

NOTICE
•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.
NOTICE
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.

Use for intended purpose/Use not for intended purpose
Use for intended purpose
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.
NOTICE
•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.
Use not for intended purpose
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.
The bypass line must not be connected in the intake line (the bleeder function will no longer be
guaranteed). The bypass line must be routed back into the supply tank.
DANGER
When carrying out maintenance work on the overcurrent valve, pay attention to
the tensioning state of the pressure spring item132! Wear safety goggles!
2.2.6 Diaphragm rupture sensor
Function:
Monitors the seals in the working diaphragm. This liquid end can continue to function for a short
period in emergency mode, i.e. full operating pressure, no leakage, even after diaphragm rupture.
Design and function description (see Fig. 9)
Liquid ends with diaphragm rupture sensors comprise a standard liquid end (item 100) a working
diaphragm (item 200) and an auxiliary diaphragm (item 148) The auxiliary diaphragm is positioned
between the back plate (item 201) and the interim plate (item 147) and forms a sealed
compartment together with the working membrane (item 200).
The leak tightness of the working diaphragm, Item 200, is monitored with a diaphragm failure
detector, Item 104, that triggers a contact signal in the event of diaphragm failure so that the
pump is stopped in the S1Ca and the diaphragm failure is indicated on a LCD.
