WARNING!

Danger from hazardous substances!

Possible consequence: Fatal or very serious injuries.

Please ensure when handling hazardous substances that

you have read the latest safety data sheets provided by the

manufacture of the hazardous substance. The actions

required are described in the safety data sheet. Check the

safety data sheet regularly and replace, if necessary, as the

hazard potential of a substance can be re-evaluated at any

time based on new findings.

The system operator is responsible for ensuring that these

safety data sheets are available and that they are kept up to

date, as well as for producing an associated hazard assess‐

ment for the workstations affected.

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.

CAUTION!

Warning of feed chemical spraying around

An unsuitable feed chemical can damage the parts of the

pump that come into contact with the chemical.

– Take into account the resistance of the wetted materials

when selecting the feed chemical - see the ProMinent

product catalogue or visit www.prominent.com/en/down‐

loads.

CAUTION!

Danger of personnel injury and material damage

The use of untested third party parts can result in personnel

injuries and material damage.

5 Functional description

The metering pump is an oscillating diaphragm pump, the stroke length of

which can be adjusted. An electric motor drives the pump.

The metering diaphragm (2) hermetically shuts off the pump volume of the

dosing head (3) from the outside. The suction valve (4) closes as soon as

the metering diaphragm (2) is moved in to the dosing head (3) and the

feed chemical flows through the discharge valve (1) out of the dosing

head. The discharge valve (1) closes as soon as the metering 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 (4)

into the dosing head. One cycle is thus completed.

5 Diaphragm rupture signaller

The diaphragm rupture warning system monitors the leak-tightness of the

multi-layer diaphragm. Together with the diaphragm rupture sensor and

downstream analysis electronics, the multi-layer diaphragm forms the dia‐

phragm rupture warning system.

The multi-layer diaphragm has an expandable point (4) on its hole circle. If

an outer layer of the multi-layer diaphragm breaks, feed chemical pene‐

trates into it under pressure and inflates this expandable point (4). Conse‐

quently the pin (2) of the safety piston (1) presses against the diaphragm

(3) of the diaphragm rupture sensor signaller so that a contact signal

switches off the pump or triggers an alarm signal (customer installed!).

Moreover, the multi-layer diaphragm prevents feed chemicals escaping in

the event of diaphragm rupture.

7 Installation

7.1 Installation, hydraulic

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 power end components).

– 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.
