Fill strainer Sealing compound
Purchasing-example:
Pump PEK-A; delivery capacity continuously
adjustable; reservoir 1,5 l; without
level switch; with filling connector; without
protective coating; with fill strainer; sealing
compound Viton.
Order-designation:
PEK-A / F / 1,5 / 0 / B / 0 / S / V
Functional principle:
Mode of work:
Apneumatically unilaterally operated piston
delivers the oil into the delivery pipe. Due to
the spring power the piston is reset in order
to suck the oil from the reservoir in. During
the suction process the delivery pipe’s
pressure will be decreased down to approx.
0,8 bar. The integrated pressure control
valve opens at 32 bar.
Note:
When air pressure is impinged suddenly,
the pressure control valve’s start-to-leak
pressure may be exceeded and that
pressure will not build up in the outlet then.
As a result, the delivery capacity will
decrease.

The safety and danger information stated in the safety data sheets of the substances used
must be taken into account at all costs.
Transportation of gases, liquefied gases, gases under pressure, vapours and liquids, the

Information on EU Directive 2002/95/EC (RoHS)
With Directive 2002/95/EC of January 27, 2003, for the limitation of the use of certain
hazardous substances in electrical and electronic devices (RoHS) material bans come into
effect from July 2006 for electrical and electronic devices newly placed on the market for
lead, cadmium, hexavalent chromium, mercury and brominated flame retardants.
In its controls and switching devices, WOERNER only uses materials which fulfil the criteria
of EU Directive 2002/95/EC.
To the extent that hexavalent chromium has been used as corrosion protection in the parts
which we produce ourselves, it has already been replaced by other environmentally
tolerable protective measures.
The mechanical devices supplied by WOERNER are not affected by EU Directive
2002/95/EC.
But as WOERNER is conscious of its responsibility towards the environment, we shall also
use materials fulfilling the requirements of the Directive for devices not covered by EU
Directive 2002/95/EC as soon as they are generally available and their use is technically
possible.
