Description
Custom Built Filters and Strainers
Rotorflush can design and manufacture custom built filters and strainers. All our strainers incorporate Rotorflush’s unique self-cleaning mechanism to prevent filter the mesh blocking.
We combine our expert knowledge of filtration and experience in precision engineering to meet our customers needs. Rotorflush Filters Ltd. can design, manufacture and deliver a purpose built self-cleaning industrial water intake strainer to the size and specification you require.
Your design can be realised in our CAD studio and delivered to you from our precision engineering workshop and test facilities in beautiful Charmouth on the UK’s Jurassic Coast.
Modular and Scalable
Our award winning self-cleaning filters and strainers are offered in standard ranges based on modular designs that can be scaled to suit a wide range of applications. We have expertise in 
producing filters across a range of industrial sectors. This enables us to produce intake strainers and screens to meet our customers’ flow rates, intake velocities and screening needs.
Although our filters have a core design, we can vary:
- Outlet size
- Filter diameter
- Filter height
- Mesh size
- Grade of steel
We can incorporate extras to assist in using and lifting our strainers, or we can design and build a wholly custom filter. Often our customers require self-cleaning strainers and filters to fit their particular installations and capacities which are outside our standard ranges.
Quality Products
All our products are well designed, manufactured in stainless steel, tried and tested, and guaranteed. Our customers know they are buying a purpose built, long-lasting quality engineered product.
Get in touch
We can build our filters to meet your flow rates and to fit your location and application or project. Call our Design Team for more information – 01297 560 229
All our custom-built self-cleaning filters and strainers can be made Eel Friendly to meet current EU and UK regulations for Eel Recovery
and to meet EPA Rule 316(b) intake velocities for the protection of marine and aquatic life
Recent Commissions
All our products are made to order, and we are more than happy to provide custom-built self-cleaning filters and strainers to your specifications.
Our larger filters are increasingly being custom built for many industrial sectors where there is a need for raw water filtration without the expense and delay of major capital works. Customers are able to filter their intake directly from the water source with minimal risk of their filter screens and pump equipment blocking. We are seeing more interest given that screening for the protection of marine life and the European Eel is now often a condition of raw water and cooling water abstraction.
Screens for use with Vertical Pumps.
Rotorflush have been commissioned to supply self-cleaning suction intakes for vertical pumps abstracting seawater for cooling.
Our self-cleaning intakes allow 2 mm aperture mesh screening at an EPA Rule 316(b) compliant intake velocity while protecting the screen and pump from blockage.
Strainers for Firefighting
Sizes and shapes can be varied. A customer wanted filters for dockside firefighting pumps at a refinery.
The strainer needed to have domed ends for strength but depth was a tight. To save space yet meet the flow rate needed we designed and built strainers with convex rather than concave ends.
Eel Screens
We provided a UK water company with 25 strainers for eel screening at raw water intakes. The self-cleaning strainers were fitted with 2 mm mesh screens and attachments for a unique lifting system.
These strainers screen millions of gallons of water for treatment ahead of the potable water supply.
An Oil and Gas customer recently commissioned five purpose built 750 m3 filters for raw water abstraction. The strength and reliability of these large industrial custom built automatic backwash filters makes them a popular and inexpensive choice when considering capital projects.
Our custom built self-cleaning filters and strainers have no need of any power supply other than the flow of water from the pump.
The design is simple, installation is easy and maintenance is minimal.
