5.1
Pump
The metering pump is an oscillating diaphragm pump, the stroke length of
which is adjustable. An electric motor drives the pump.
5.2 Liquid end
The diaphragm (2) hermetically shuts off the pump volume of the dosing
head (4) towards the outside. The suction valve (1) closes as soon as the
diaphragm (2) is moved in to the dosing head (4) and the feed chemical
flows through the discharge valve (3) out of the dosing head. The dis‐
charge valve (3) closes as soon as the diaphragm (2) is moved in the
opposite direction due to the vacuum pressure in the dosing head and
fresh feed chemical flows through the suction valve (1) into the dosing
head. One cycle is thus completed.
The integral relief valve normally operates as a simple, directly controlled
bleeder valve. The feed chemical then flows out through the hose connec‐
tion, e.g. into a storage tank, as soon as the pressure exceeds the pre-set
pressure value.
The integral relief valve can only protect the motor and the gear, and then
only against impermissible positive pressure that is caused by the
metering pump itself. It cannot protect the system against positive pres‐
sure.
The integral relief valve works as a bleed valve if the rotary dial is turned
clockwise up to the "open" stop, acting as a priming aid when starting up
the pump against pressure.

5.4 Multi-layer safety diaphragm
With visual diaphragm rupture sensors, in the event of a diaphragm rup‐
ture, the lowered red cylinder (6) springs forward beneath the transparent
cover (7) so that it then becomes clearly visible - see
Fig. 9.
With the electrical diaphragm rupture sensor, a switch is switched. A sig‐
nalling device must be connected to signal the diaphragm rupture.

WARNING!
EX pumps in areas at risk from explosion
–It is essential that metering pumps to be used in areas at
risk from explosion are fitted with an appropriate safety
relief valve on the outlet side of the metering pump (to
protect it from excessive heating up from overloading
and from impact sparks resulting from overloading trig‐
gered by the breakage of drive parts).
–
In the event of different temperature classes with the
various components, the possible uses of the complete
pump are based on the component with the lowest tem‐
perature class.
–Diaphragm pump with mechanically actuated diaphragm,
e.g. MTMa.., TZMa.., Sigmas S1Ba...., S2BaHM...,
S3Ba: no additional action is required, but in principle
use the design with Ex"i" diaphragm rupture indicator.
–Ensure that installations in areas at risk from explosion
are checked by a "recognisably qualified and skilled"
operative.
–Please observe the relevant national regulations and
guidelines during installation!
WARNING!
Danger of fire with flammable feed chemicals
–Combustible media may only be transported using stain‐
less steel dosing heads. In exceptional cases where this
is not possible, PTFE with carbon can be used, whereby
our TT_ versions are manufactured from this conducting
plastic. Here, the operator is urged to take special care
due to the low mechanical strength.
–
Only designs of metering pump with Ex"i" diaphragm
rupture indicators are permitted in principle to meter
flammable media.
–The following applies to all metering pumps for the
metering of combustible media:
During filling and draining of the liquid end, an expert
must ensure that feed chemical does not come into con‐
tact with oxygen.
WARNING!
Warning of feed chemical reactions to water
Feed chemicals that should not come into contact with water
may react to residual water in the liquid end that may origi‐
nate from works testing.
–Blow the liquid end dry with compressed air through the
suction connector.
Then flush the liquid end with a suitable medium through
–
the suction connector.
WARNING!
The following measures are an advantage when working with
highly aggressive or hazardous feed chemicals:
–Install a bleed valve with recirculation in the storage
tank.
Install an additional shut-off valve on the discharge or
–
suction ends.
18
Page 19
P_SI_0021
Installation, hydraulic
CAUTION!
Warning of feed chemical spraying around
PTFE seals, which have already been used / compressed,
can no longer reliably seal a hydraulic connection.
–New, unused PTFE seals must always be used.
CAUTION!
Suction problems possible
The valves may no longer close properly with feed chemicals
with a particle size of greater than 0.3 mm.
–Install a suitable filter in the suction line.
CAUTION!
Warning against the discharge line bursting
With a closed discharge line (e.g. due to a clogged discharge
line or by closing a valve), the pressure that the metering
pump generates can reach several times the permissible
pressure of the system or the metering pump. This could
lead to lines bursting, resulting in dangerous consequences
with aggressive or toxic feed chemicals.
–Install a relief valve that limits the pressure of the pump
to the maximum permissible operating pressure of the
system.
Fig. 14: Moulded composite seals with
corrugated insert
CAUTION!
Uncontrolled flow of feed chemical
Feed chemicals can leak through a stopped metering pump if
there is back pressure.
–Use an injection valve or a vacuum breaker.
CAUTION!
Uncontrolled flow of feed chemical
Feed chemical can leak through the metering pump in an
uncontrolled manner in the event of excessive priming pres‐
sure on the suction side of the metering pump.
–Do not exceed the maximum permissible priming pres‐
sure for the metering pump.
–Arrange the installation properly.
CAUTION!
Warning against leaks
Leaks can occur on the pump connection depending on the
insert used.
–The pump is supplied with PTFE moulded composite
seals with a flare, which are used for the pump connec‐
tions. They seal the connections between grooved pump
valves and the grooved inserts from ProMinent - see
Fig. 14.
–
In the event that an unflared insert is used (e.g. third
party part), an elastomer flat seal must be used - see
Fig. 15.

Integral relief valve
CAUTION!
Warning of backflow
Liquid ends, foot valves, back pressure valves, relief valves
or spring-loaded injection valves do not constitute absolutely
leak-tight sealing elements.
–Use a shut-off valve, a solenoid valve or a vacuum
breaker for this purpose.
WARNING!
Product can be dangerously contaminated
Only with the design "Physiologically safety with regard to
wetted materials".
If the integral bleed valve or the integral relief valve opens,
the feed chemical comes into contact with physiologically
harmful seals.
–Do not route feed chemical that escapes from the inte‐
gral bleed valve or the integral relief valve back into the
process.
CAUTION!
Danger due to incorrect use of the integral relief valve
The integral relief valve can only protect the motor and the
gear, and then only against impermissible positive pressure
that is caused by the metering pump itself. It cannot protect
the system against positive pressure.
–Protect the motor and gear of the system against posi‐
tive pressure using other mechanisms.
–
Protect the system against illegal positive pressure using
other mechanisms.
CAUTION!
Warning of feed chemical spraying around
If no relief valve was connected to the overflow line, the feed
chemical sprays out of the hose connection as soon as the
relief valve opens.
–An overflow line must always be connected to the inte‐
gral relief valve and be fed back to the storage tank or if required by the regulations - into a special storage
tank.
CAUTION!
Danger of cracking
Cracking of the PVT liquid end can occur if a metal overflow
line is connected to the relief valve.
–Never connect a metal overflow line to the relief valve.
20
Page 21
P_SI_0023
Installation, hydraulic
CAUTION!
Danger of the integral relief valve failing
The integral relief valve no longer operates reliably with feed
chemicals having a viscosity of greater than 200 mPa s.
–Only use the integral relief valve with feed chemicals
having a viscosity up to 200 mPa s.
CAUTION!
Warning against leaks
Feed chemical which remains in the overflow line at the relief
valve, can attack the valve or cause it to leak
–Route the overflow line with a continuous slope and
moreover with the tube nozzle pointed downwards - see
Fig. 16.
If the overflow line is fed into the suction line, the bleed func‐
tion is blocked.
Therefore lead the overflow line back into the storage tank.
Fig. 16: Permissible alignment of the relief
valve
Diaphragm rupture sensor
When operating the integral relief valve close to the opening
pressure, a minimal overflow into the overflow line can occur.
CAUTION!
Danger resulting from unnoticed diaphragm rupture
If the pump has been ordered with an electric diaphragm rup‐
ture sensor, it still has to be installed.
–Screw the enclosed diaphragm rupture sensor into the
liquid end.
CAUTION!
Warning of unnoticed diaphragm rupture
Only above approximately 2 bar system back pressure is a
signal generated upon a diaphragm rupture.
–Only rely on the diaphragm rupture sensor at back pres‐
sures greater than 2 bar.

ture sensor, it must also be electrically installed.
–Install the enclosed diaphragm rupture sensor electri‐
cally to a suitable monitoring device.
a) Diaphragm rupture sensor with switch contact
–
The cable can be poled as required.
b) Namur sensor, inherently safe
The monitor / power supply installed by the customer must be able to eval‐
uate the current variations of the Namur sensor for indicating a diaphragm
rupture!

Safety notes
WARNING!
EX pumps in areas at risk from explosion
–An appropriately skilled operative should check whether
the appropriate installation information from the "Installa‐
tion " chapter has been implemented correctly.
WARNING!
Fire hazard with flammable media
Only with combustible media: These may start to burn when
combined with oxygen.
–During filling and draining of the liquid end, an expert
must ensure that feed chemical does not come into con‐
tact with oxygen.
CAUTION!
Feed chemical could escape
–Check suction and discharge lines and liquid end with
valves for leak-tightness and tighten if necessary.
Check whether the necessary flushing pipes or bleed
–
lines have been connected.
Diaphragm rupture sensor
CAUTION!
Prior to commissioning, check that the power end motor and
corresponding ancillary equipment is connected in compli‐
ance with the regulations.
CAUTION!
When using pumps with speed control, observe the instruc‐
tions in the frequency converter operating instructions.
CAUTION!
Danger resulting from unnoticed diaphragm rupture
If the pump has been ordered with an electric diaphragm rup‐
ture sensor, it still has to be installed.
–Screw the enclosed diaphragm rupture sensor into the
liquid end.
CAUTION!
Warning of unnoticed diaphragm rupture
Only above approximately 2 bar system back pressure is a
signal generated upon a diaphragm rupture.
–Only rely on the diaphragm rupture sensor at back pres‐
sures greater than 2 bar.
28
Page 29
Start up
CAUTION!
Possible environmental and material damage
In event the red gear bleeding plug is sealed, during opera‐
tion it prevents any pressure compensation between the
drive housing and the surroundings. This ensure that oil can
be pushed from the drive housing.
–Remove the gear bleeding plug before commissioning.
Remove the gearbox vent stopper
Checking the oil level
Checking the direction of rotation
Using the integral relief valve
Before start up pull the red gearbox vent stopper off, see chapter "Over‐
view of equipment and control elements".
When the pump is idle, check whether the oil level in the pump is in the
middle of the oil level indicator.
This will rule out the pump losing oil and suffering damage.
When commissioning the unit, check whether the drive motor is rotating
correctly - check this against the arrow on the motor housing or the dia‐
gram in the chapter entitled "Electrical Installation."
CAUTION!
Danger due to incorrect use of the integral relief valve
The integral relief valve can only protect the motor and the
gear, and then only against impermissible positive pressure
that is caused by the metering pump itself. It cannot protect
the system against positive pressure.
–Protect the motor and gear of the system against posi‐
tive pressure using other mechanisms.
–Protect the system against illegal positive pressure using
other mechanisms.
Priming against pressure
CAUTION!
Danger of the integral relief valve failing
The integral relief valve no longer operates reliably with feed
chemicals having a viscosity of greater than 200 mPa s.
–Only use the integral relief valve with feed chemicals
having a viscosity up to 200 mPa s.
1.Hydraulically isolate the discharge line from the pump using an iso‐
lation device.
2.Turn the rotary dial on the integral relief valve in a counter-clockwise
direction as far as the "open" stop.
The excess pressure escapes through the hose connector.
ð
3.Run the pump until the feed chemical coming out of the hose con‐
nector is free from bubbles.
4.Turn the rotary dial on the integral relief valve in a clockwise direc‐
tion up to the "close" stop.
The pump can be started.

Technical data
During operation with an automatic stroke length adjustment control
together with a variable speed motor, the stroke rate must not fall below
30 strokes / min. Otherwise technical problems occur, because the
mechanical resistance of the stroke adjustment spindle becomes too high.
