EXAMPLE OF APPLICATION

Gardner Denver Thomas GmbH
D-8178 Puchheim www.rtpumps.com
Compressors, vacuum and fluid pumps and leak detectors

Gardner Denver is a manufacturer of compressors, vacuum and fluid pumps for medical technology,
environmental technology, automobile industry, food technology, analytics, hygiene and cleaning, as well as
leak detectors for tanks and piping systems, approx. 230 employees in Puchheim, sales volume with
SERTO: ca. € 33’000-- / year.

APPLICATION
SERTO products: Stainless steel 1.4571 and brass unions
Installation: ASF® leakage detection systems for monitoring double-walled tanks and piping
systems via positive pressure and vacuum

PARAMETERS
Medium: Air for positive pressure and vacuums, nitrogen for positive pressure
Pressure: 1-6 bar / vacuum

Vacuum leak detector Vakumatik 17 Ex
with SERTO unions in the control and
measurement lines

In the area of measurement and control lines, thin-walled tubes in diameter 8 mm x 0.7 mm are used. The
SERTO system was the system of choice in product development because the thin-walled copper or
stainless steel tubes are not damaged when mounting compression ferrules and a permanent tight seal can
be made.

„We have been using these unions for more than 15 years and are very satisfied with the products
from SERTO.”
