HERM HIGH EFFICIENCY RUBBER MOUNT

Utility Model Right No.0242251 / Design Registered No.0302182, 0302183, 0305227(KIPO)

31

Product Overview

- Type according to the characteristics of vibration source.

Active type : Prevents the transmission of vibration generated

from machines(pump, motor, compressor, etc) to the outside.

Passive type : Create less vibration environment so that

equipment without vibration source safely operate from

external vibration.

- Since vibration problems require high dynamic analysis /

experiment technique, measurement / analysis / evaluation

technique and reliable measures, pay attention to approaching

methods.

- Can obtain stable and flexible field application and high

efficiency anti-vibration effect.

Product Features

- High efficiency rubber mount with natural frequency of 4.5Hz

0r below.

- Reliable durability.

- Flexible load applicability, as mixing and using 200kg and

500kg elements.

- Effective to structure-borne noise.

Product Configuration & Specification

- High efficiency high-damp anti-vibration rubber

- Upper housing

- Leveling Bolt, Nut

Product usage & Application fields

- Pump(single stage volute, multi stage volute and turbine

etc)

- AHU(horizontal, vertical, composite, integrated, etc)

- Fan(Sirocco, airfoil, turbo, double suction etc)

- Anti-vibration for riser, double floor and other various pipes)
