Anti-Vibration Mounts for Pumps

Like anything with moving parts, pumps vibrate. When they do, that vibration can be harmful to the pump itself, limiting its working life. It can be harmful to other components in proximity to the pump, with vibration increasing wear and causing fixings to come loose. And it can transmit along the length of piping systems, increasing unwelcome transient noise.

When should you install pump vibration isolators?

Any pump operating above ground level is likely to cause unwelcome vibration, so anti-vibration components should be installed. Additionally, any pump operating in sound sensitive areas should be isolated. That may include the pump in the HVAC system that feeds a health facility or laboratory with vibration sensitive equipment. It could equally be required in a residential block where noise could cause complaints.

Additionally, if the pump is a supplied component being used in your own product, check the pump manufacturer’s instructions. They may detail the type of vibration isolation required.

Which anti-vibration component?

To determine the right isolation component, you’ll need to consider the weight of the pump, the direction of the stress forces and the movement required by the isolator:

  • High Deflection Bell Mounts
    A high level of vibration isolation, with perfect absorption of axial stresses and side deflections limited to guarantee good stability.

  • Marine Mounts
    Large static deflections when the rubber works in shear and compression. Integral fail-safe device to provide shock and failure protection for pumps used in marine applications.

  • Heavy Duty Bell Mounts
    Heavy duty vibration isolation for large pumps.

  • Buffers & Stops
    Use in a wide range of pump applications to soften or cushion contact between adjacent parts.

Technical Competence

Our technical expertise is market leading, with high levels of experience gained over 60 years in all applications.

The technical support we can offer include product conceptualisation, design/ development (for the products, tooling and processes), product validation (via life cycle or durability testing), and implementation into full volume production.

All this is project managed inhouse, with design/development performed using the latest CAE/FEA systems, tooling developed and manufactured inhouse, testing using one of the most comprehensive laboratories in the industry, and implementation using the wide range of plant and equipment available.

As we are able to provide a full turnkey service from concept stage, through to initial prototypes (usually within a small number of weeks from go ahead), then onto production volumes within the critical milestones set out by the customer, our NPI leadtimes are unbeatable within the industry.

Finally, all our activities are closely controlled in accordance with ISO9001:2015 & IATF16949:2016.


The Fibet Group hold Quality Certification for ISO9001:2015 and ISO TS16949:2009, which can be viewed below:
