Safety

1 Safety

1.1 Notes on Safety

WARNING

• Immediately switch off the pump in the case of emergency!

Use the pump power switch or an emergency stop switch in your working environment!

• When installing the metering pump also observe the installation instructions for

devices in explosive areas; for Europe the European operator directive 99/92/EC
(ATEX137) and the ATEX Product Directive 94/9/EC (ATEX 95), implemented in Germany
by the new health and safety legislation!

• When using the metering pump for metering flammable media, observe (in Europe) the

European Operator Guideline 99/92/EC (ATEX 137, previously ATEX118a), implemented
in Germany with the new operating safety directive and the German dangerous
chemicals directive.

• Observe also all relevant standards e.g. DIN EN 60079-10/14 and DIN VDE 60079-11 for

installations in explosion-threatened areas and DIN VDE 0118 for the installation of
electrical equipment in explosion-threatened areas by day.

• Note all national directives which apply to the installation when installing outside

Germany.

CAUTION

• Pumps must be accessible at all times to facilitate operation and maintenance.

Do not obstruct or block access routes!

• Only specially trained and authorized persons are permitted to maintain and repair

metering pumps and their peripheral equipment!

• Always depressurize the liquid end first before carrying out any work on the pump!

• If hazardous or unknown metering media are used, discharge and flush the liquid end

before carrying out any work on the pump!

• Observe the safety data sheets of the metering liquids!

• Always wear protective clothing (goggles, gloves) when handling hazardous or

unknown liquids! This applies in particular to working on the liquid end!

®

• Assembly of ProMinent

metering pumps with parts not tested and approved by
ProMinent is prohibited and can result in damage to persons and property, for which
no liability will be accepted!

IMPORTANT

• Adjust the stroke length only with the pump running when the load on the stroke length
setting pin is relieved temporarily!
Release the lock before adjusting the stroke length!

• Only use clamping rings and hose sockets suitable for the relevant hose diameter as
well as genuine ProMinent hoses with the specified hose dimensions and wall
thickness, otherwise the stability of the connection cannot be guaranteed!

ProMinent

NOTE

•Avoid reducing the hose sizes!

• Use the next higher pipe cross-section or a pulsation damper for long hose lines and
media with higher viscosity!

consists of the main components

2.1 Functional principle

Metering is based on the pulse burst principle:
A pulse produces a magnetic field around the solenoid,
the solenoid attracts a moving thrust piece,
as a result, the diaphragm displaces the medium in the liquid end via a pressure control valve,
the valve closes on the intake side.

The magnetic field decays on completion of the switch-on pulse,
the thrust piece of the solenoid is reset by a reset spring,
the diaphragm returns to its initial position, thus initiating an intake stroke,
which closes the pressure valve and the media is drawn in on the intake side.

2.2 Construction / functional description diaphragm rupture indicator (optional)

The diaphragm rupture signalling system monitors the leak-tightness of the operating
diaphragm.

The liquid end of EXBb with diaphragm rupture signalling has instead of only one operating
diaphragm an additional diaphragm comprising the operational diaphragm and an additional
safety diaphragm, and is equipped with an intrinsically safe diaphragm rupture sensor (see
figure 1).

Page 10

ProMinent

®

Design and Function

The safety diaphragm is situated between the top plate and the spacer plate and forms a sealed
interim chamber with the working diaphragm.

Function It serves to monitor ruptures in the working diaphragm and protects the power end from

corrosion and the environment from chemical leaks in the case of diaphragm rupture.
Even after diaphragm rupture, this liquid end can continue to operate in emergency mode at full

working pressure and without leaks until the diaphragm is changed.

fig.: 1

IMPORTANT

If the diaphragm ruptures, an electrical signal is triggered when the system back pressure
reaches approx. 2 bar.

IMPORTANT

Precise pump feed cannot be guaranteed after a working diaphragm rupture.

2.3 Feed rate

The delivery capacity is determined by the stroke length and the stroke frequency (rate).
The stroke length can be steplessly adjusted with the control knob for stroke length (14) during

operation from 100 % to 10 % and then locked. The maximum stroke length is 1.25 mm, 0.63
mm for type EXBb_1000.

A setting of 0 to 110 (120) stroke/min can be set manually with the control knob for stroke
frequency (rate) (16).

At a maximum stroke length and rate and a max. backpressure of 1.5 bar to 25 bar, the
diaphragm-operated metering pumps deliver at a rate of 0.2 l/h to 60 l/h.

Design and Function

2.4 Control types

Version “Internal stroke rate setting” (identity code characteristic “Control type”: 0):

The controlling pulse is internally generated, stroke length and stroke rate can be manually
adjusted using the control buttons on the operating panel.

Versions “External contact control” (identity code characteristic “Control type”: 1, 4):

The controlling pulse is externally generated, from potential-free or semiconductor contacts and
fed to the drive unit via the “external control” jack; examples are contact water meter or
DULCOMETER® controls.

Versions “Analog control x - 20 mA”
(Identity code characteristic “Control type”: 2, 3, 5, 6):

An external, analogue signal is fed to the drive unit via the “External control” jack;
the stroke rate changes proportionally according to the 0 .. 20 mA or 4 .. 20 mA signal.

Versions “Internal stroke rate setting with pause function”
(Identity code characteristic “Control type”: 7, 8):

As for version “Internal stroke rate setting”, however there is also the possibility of switching the
metering on and off via an external semiconductor contact or potential-free contact.

NOTE

All control types, that can be controlled via an input, can be supplied with an “External
control” input of “non-intrinsically safe” or “intrinsically safe” type [i, a].

Technical data

3.4 Accuracies

min.: -5 %, max.: not specified
at max. stroke length and max. backpressure,
in all material versions.

Better than ± 2 %
under constant conditions and min. 30 % stroke length;
observe following notes:

• All specifications refer to metering measurements with water at 20 °C.

• Constant backpressure, above 1 bar if possible.

• If metering takes place via a free outlet, a pressure retention valve must be used to generate
a backpressure of min. 1.5 bar (refer to the installation examples).

• Wherever possible, lay intake and metering lines with a constant rising gradient.

• If the liquid level of the supply tank is above the pump during operation, admission pressure
will be applied on the intake side; in this case, the backpressure should be so high that there
is a minimum differential pressure of 1.5 bar otherwise a pressure retention valve or a spring­loaded injection valve with corresponding admission pressure must be used.

NOTE

A pressure retention valve or a spring-loaded injection valve is not an absolutely tight­closing shut-off element. For this reason, an intake valve which is closed when the
metering pump is at a standstill, must be installed if admission pressure is applied on the
intake side.
