1Preamble

ProMinent®Pneumados is a pneumatically-operated metering pump.

In contrast to solenoid-driven metering pumps, the metering stroke of this pump is effected by a

pneumatically actuated diaphragm, the suction stroke by spring force.

The delivery capacity can be varied via the stroke frequency and the stroke length setting.

Metering strokes The external electrically-pneumatically or pneumatically activated compressed air valves facilitate

a setting of up to 180 metering strokes per minute.

Stroke length The stroke length and thus the stroke volume can be set between 10 and 100%.

Areas of application Typical areas of application are:

•Feeding stuff treatment -

Metering and spraying of feeding stuff with flavouring agents

•Painting plants -

Metering of coagulants

•Greenhouses -

For metering of fertilisers and minerals compounds

•Car wash -

Metering of cleaning agents, shampoo, brighteners, wax, drying agents as well as for the

treatment of recycling water via metering of flocculants, pH adjusters, defoaming agents,

and emulsion breakers

•in all plants with central control (e.g. PLC) and compressed air supply

Function

2Function

Capacity range ProMinent®Pneumados is a pneumatically operated metering pump with a capacity range from

max. 0.76 to 16.7 l/h at a max. backpressure of 16 –2 bar.

Compressed air consumption The compressed air consumption amounts to approx. 47 l/min at 6 bar, preferably non-oiled or

also oiled compressed air.

2.1 Functional principle

Pressure stroke Compressed air is applied to the pressure chamber within the housing via an external pneumatic

valve. This displaces a pneumatic diaphragm and the resulting axial movement is transferred to

the metering diaphragm via a tappet. This diaphragm impulsively expels the metering medium

from the liquid end through the pressure valve and the balls on the suction side close.

Suction stroke The pneumatic valve having switched, the pressure chamber is relieved and the tappet together

with the metering diaphragm is restored to its original position through the spring. The medium is

sucked into the liquid end through the suction valve and the balls on the pressure side are closed.

2.2 Pump drive

The Pneumados pump drive is operated solely pneumatically with a continuous max. stroke

frequency of 180 strokes/min.

The metering stroke is set to 10 - 100% using a stroke length adjustment (10).

The stroke length is max. 1.25mm.

NOTE

Settings should only be made with the pump in operation – when the adjustment pin of the

metering stroke is momentarily relieved!

2.3 Delivery unit

The Pneumados metering pump is equipped with genuine ProMinent®beta delivery units of the

type series 1000 - 0220.

Liquid end materials The liquid end with double-ball valves in the suction and pressure valves is available in the

following material types:

PV = PVDF

SS = stainless steel (material number 1.4571).

The DEVELOPAN®metering diaphragm has a PTFE layer.

2.4 Pump control

A pump control is required to operate the Pneumados.

Function

2.4.1 Electrical-pneumatic control

An electrical pulse generator drives a pneumatic solenoid valve. During the metering stroke, the

pneumatic solenoid valve applies compressed air to the pump; during the suction stroke, this air

volume is released into the open from the solenoid valve via the vent connection "R".

Technical data of the electrical-pneumatic control:

Electrical control Via pulse generator –pulse control of PLC control or pulse generator relay with pulse duration of

approx. 250ms, e.g. flashing relay, adjustable between 0.1 and 1s, 24Vdc

Pneumatic control Via 3/2-way solenoid valve, e.g. MHE3-M1H-3/2G-QS-6-K-525152 (order no. 1030275)

Nominal width ≥3,0 mm

Nominal flow rate ≥200 I/min

Line connection QS-6 (for hose 6x4)

5Notes on safety

WARNING

•The pumps must be accessible any time for operation and maintenance, access may not

be hindered or blocked!

•Pneumados metering pumps can be operated with a max. permissible air pressure of 8

bar. Corresponding measures have to be taken to ensure that this pressure is not

exceeded – if required by installing a safety valve or a pressure limiting valve upstream

of the pump!

•Always rinse the liquid end first before commencing maintenance and repair work if

hazardous or unknown metering media are used!

•When metering hazardous or unknown metering media, suitable protective equipment

(goggles, gloves …) must be worn when working at the liquid end! Observe the safety

data sheets of the metering media!

•Switch off the pump control and close the compressed air supply line first before

starting any work at the pump! Always depressurise the metering line! Always empty

and rinse the liquid end! Observe the safety data sheets of the metering media!

Proper use •The pump is only designed for metering liquid media.

•All other uses or modifications are prohibited!

•The pump must not be used to meter gaseous media or solids.

•The pump is not designed for use in Ex areas.

•The pump may only be used in compliance with the technical specifications stated in the

operating instructions and in the technical data.

•The pump may only be operated if all components were installed in compliance with the

technical documentation and a proper installation was performed.

•The pump may only be operated by trained personnel.

IMPORTANT

•Settings should only be made with the pump in operation – when the adjustment pin of

the metering stroke is momentarily relieved!

•Only use the clamping rings and hose grommets specified for the corresponding hose

diameter as well as genuine hoses of the specified hose dimensions and wall thicknesses.

Otherwise, the stability of the connection is not guaranteed!

•Avoid reducing the hose sizes! In case of long lines and viscous media, the next higher

line cross-section or a pulsation dampener should be used!
