Rubber compensators
Design 1 + 2

Design 1 with rotating flanges

(Fig. 1) For axial expansion, our movement limiters (Fig. 2)
serve a stroke-limiting function.

Highly elastic pipe connectors
For all sectors of industry, apparatus and pipeline construction, power plants, shipbuilding, fuel pumps, heating, climate control and ventilation plants, etc.
Use:
Absorption of axial and radial expansion, noise, vibrations
and oscillations

Misalignment

Distortion

Vibration

Compensation of assembling imperfections

For lateral expansion absorption and for noise absorption, the
movement limiters serve to relieve the load on the anchors.
Use:
For noise absorption, rubber compensators with movement
limiters (Fig. 2) and a shorter overall length are generally
recommended for installation.
A shorter installation is also recommended for expansion
absorption at a traction and thrust of +/- 20 mm. The installation for other operating behaviours is based on the expansion absorption. However, under no circumstances should
the overall length exceed 130 mm. In the event of low pressure and high suction operation, use a high-grade steel
inner support ring.
Available in various rubber qualities
Type

Normal

Traction

Thrust

For subsidence of buildings and containers, assembling
imperfections, for electrical insulation, for nearly total noise
absorption in pipelines, domestic supply mains, heating systems, pump and motor connections.

EPDM*

EPDM*

for warm water, wastewater (including those with
added acids and bases), water and drinking water (not suitable for media containing oil).
yellow Perbunan*

for petroleum products, premium fuel and cooling water with corrosion protection oils up to 90 °C

Construction:
Smooth inside and out, high pressure-resistant textile fabric
interlinings with moulded rubber stub end vulcanised on
both sides, with embedded steel wire reinforcement that
allows for accurate and complete adaption to the
counterflange. Therefore no gaskets are necessary.

Installation instructions

Low inherent resistance
allows a very simple installation (no additional
tools necessary).
The pipelines are to be
secured by a sufficient
number of anchors (fixed
points).

Special advantages:
Low inherent resistance, short installation length, excellent
axial and radial expansion absorption and noise reduction.
Fixed point
