Two sets of operating instructions are required for the safe, correct and proper operation of the metering pumps: the
product-specific operating instructions (for instance for beta) and the "General Operating Instructions for ProMinent® Sole‐
noid Metering Pumps".
Both sets of operating instructions are only valid when read together.

Information
This provides important information relating to the correct
operation of the device or is intended to make your work
easier.
Safety information
Safety information is identified by pictograms - see Safety Chapter.
Two sets of operating instructions are required for the safe, correct and
proper operation of the metering pumps: The product-specific operating
instructions and the "General Operating Instructions for ProMinent® Sole‐
noid Metering Pumps".
Both sets of operating instructions are only valid when read together.
Please read these operating instructions carefully before use! Do not dis‐
card!
Please state identity code and serial number, which you can find on the
nameplate when you contact us or order spare parts. This enables the
device type and material versions to be clearly identified.
In order to make it easier to read, this document uses the male form in
grammatical structures but with an implied neutral sense. It is aimed
equally at both men and women. We kindly ask female readers for their
understanding in this simplification of the text.

1 Safety Chapter
The following signal words are used in these operating instructions to
identify different severities of a hazard:
Signal word Meaning
WARNING Denotes a possibly hazardous sit‐
uation. If this is disregarded, you
are in a life-threatening situation
and this can result in serious inju‐
ries.
CAUTION Denotes a possibly hazardous sit‐
uation. If this is disregarded, it
could result in slight or minor inju‐
ries or material damage.
The following warning signs are used in these operating instructions to
denote different types of danger:
Warning signs Type of danger
Warning – high-voltage.
Warning – danger zone.
WARNING!
Warning of hazardous or unknown feed chemical
Should a hazardous or unknown feed chemical be used, it
may escape from the hydraulic components when working
on the pump.
– Take appropriate protective measures before working on
the pump (protective eyewear, protective gloves, ...).
Read the safety data sheet on the feed chemical.
–Drain and flush the liquid end before working on the
pump.
CAUTION!
Warning of feed chemical spraying around
Feed chemical can spray out of the hydraulic components if
they are manipulated or opened due to pressure in the liquid
end and adjacent parts of the system.
– Disconnect the pump from the mains power supply and
ensure that it cannot be switched on again by unauthor‐
ised persons.
– Depressurise the system before commencing any work
on hydraulic parts.

danger

CAUTION!
Warning of illegal operation
Observe the regulations that apply where the unit is to be
installed.
NOTICE!
Danger from incorrect dosing
Should a different liquid end size be fitted, this will change
the dosing behaviour of the pump.
– Have the pump reprogrammed in the works.
In an emergency either press the customer installed emergency-off switch
or disconnect the pump according to the emergency-off management of
your system!
If feed chemical escapes, also depressurise the hydraulic system around
the pump. Observe the safety data sheet for the feed chemical.

2 Assembly
WARNING!
Risk of electric shock
If water or other electrically conducting liquids penetrate into
the drive housing, an electric shock may occur.
– Position the pump so that drive housing cannot be
flooded.
CAUTION!
Danger from incorrectly operated or inadequately maintained
pumps
Danger can arise from a poorly accessible pump due to
incorrect operation and poor maintenance.
– Ensure that the pump is accessible at all times.
– Adhere to the maintenance intervals.
Capacity too low
The liquid end valves can be disrupted by vibrations.
–
Secure the metering pump so that no vibrations can
occur.
Capacity too low
If the valves of the liquid end do not stand vertically upwards,
they cannot close correctly.
–
Suction and discharge valves must stand vertically
upwards (for self-bleeding liquid end, the bleed valve).
Mount the metering pump with the pump foot on a horizontal, level
and load-bearing supporting surface.

3.1 Overview and Information on Accessories
In addition to a correctly selected metering pump, individually combined
hydraulic and electrical accessories are needed for the perfect operation
of metering systems. A number of accessories are shown on the following
pages, which are not always needed but provide an overview of the pos‐
sible options. We would be happy to assist with the selection of the right
accessories for your metering tasks and are also available for ongoing
advice, for instance on pipe calculations.

System components Function Use
Metering pump* A Metering a defined volume in liquid into
a system. Control: manual or automatic
(external signal)
Perfect adaptation to metering tasks is
possible thanks to the variably adjustable
metering volume and external control
options.
Injection valve* B Non-return valve
(Vacuum breaker)
... with closed pipe systems to prevent
backflow and mixing with the discharge
line.
As a back pressure generator ... for use with pipe systems with a free
outlet, to generate a defined back pres‐
sure.
Shut-off valves C To split the pipe system into sections
(functional sections)
... for maintenance, renovation or repair
work to shut down parts of the system.
Pulsation dampener D Smooths out pulsation in the pipe (dis‐
charge side), generates a low-pulsation
flow
... for use with long pipes to minimise pres‐
sure loss.
... to generate continuous flow/metering.
... to avoid disruptive pipe vibrations.
Back pressure valve* E Generates a defined back pressure
(configurable)
... for use with pipe systems with a free
outlet, to guarantee the correct operation of
the metering pump.
... when using a pulsation dampener
Multifunctional valve* F Generates a defined back pressure ... for use with pipe systems with a free
outlet, to guarantee the correct operation of
the metering pump.
Prevents through-suction ... with a positive pressure difference
between the suction line and discharge
line.
Priming aid ... when operating the pump against pres‐
sure.
Relief device for the discharge line ... e.g. for repairs
Opens up a relief line when a pressure
limit value is set
...as a safety device to protect the metering
system from overloading by the metering
pump.
Relief valve* Opens up a relief line when a pressure
limit value is set
...as a safety device to protect the metering
system from overloading by the metering
pump.
Level switch G Signals the liquid level of the storage
tank
(two-stage design (with pre-warning) or
single-stage)
...for the correct operation of the system.
...to display a pending change of tank or fill
the storage tank.
...to protect the metering system from
sucking dry.
Foot valve* H Non-return valve (vacuum breaker) ... to protect the suction line from running
dry (e.g. when changing tanks).
With filter meshes as a coarse filter ...to protect the metering pump from coarse
particles of solids.
Manometer I
(general pressure measuring
device)
Displays the actual pressure, for
example at the pressure connector of
the metering pump
...to determine the actual operating pres‐
sure in the discharge line.
...crucial to adjust the back pressure valve
or relief valve.
Installation, hydraulic

System components Function Use
Vacuum cylinder Smooths out pulsation in the pipe (suc‐
tion side), generates a low-pulsation
flow
... to reduce pressure losses with longer
suction lines.
Priming aid ... as a priming aid together with a vacuum
pump.
Filter Filters coarse particles of solids from
the suction flow
... to protect metering pump and system
from dirt and increased wear and tear.
Solenoid valve Automatic shut-off valve
Control: for example electrically locked
by the metering pump's mains power
supply
... as a safety device for shutting off (tightly
sealing) the discharge line when the
system is idle.
CAUTION!
* The system components in the table labelled with a * are
not absolutely leak-tight shut-off elements.
– For this purpose use a shut-off valve C or a solenoid
valve.
