Triflex Mountings
Mounts for engines, compressors, generators, marine engines and other installations
where anti-vibration mounts are required. GMT manufacture two main types of
Triflex mountings, Type 1 and Type 2. These are available in a variety of sizes with
many held in stock. Please contact our technical sales department for assistance
with selection.
Triflex Mountings (Type 1)
GMT Triflex Type 1 mountings have been developed
to provide vibration isolation against heavy duty
machinery including diesel generators, compressors,
precision machinery and electronic installations. The
mountings provide relatively high deflections and the
design is such that there are different degrees of
stiffness in the three main axes. A rebound control
option is available upon request.

Triflex Mountings (Type 2)
GMT Triflex Type 2 mountings have been developed for the insulation of static and mobile
machines and engines. Mounts have DNV type approval for the flexible mounting of propulsion
and auxiliary machinery. Applications include generators, marine engines, compressors, fans and
pumps. The mountings provide different degrees of stiffness in the three main axes and also have
integrated rebound control.

Large Triflex Mountings
GMT Large Triflex Mountings have been developed for the insulation of static and mobile
machines and engines for the load range 8kN to 20kN. Applications include medium/
large marine engines and generators. The mounts provide different degrees of stiffness
in the three main axes and also have integrated rebound control. These parts can be
manufactured and supplied with or without the adjustable top bolt and with or without the
four tie down bolts.
