Frequently Asked Questions

All our filter systems are designed for continuous use in all conditions. 

We recommend the use of some form of dry run protection, float switches and electronic controls to ensure that changing conditions do not affect the performance of the filter.

The principal of the self-cleaning filter is a continuous cycle of blowing material away from the filter with a small amount of filtered liquid, in between drawing in large amounts of filtered liquid. 

If a large object such as a plastic bag was to be sucked onto the surface of the filter then this will normally be removed from the screen by the backwash jets.

The filters leave the solids in the water you are pumping from. Put another way the filters extract a filtered supply from the dirty water.

No, they won’t. As a rule of thumb, they work in water with some solids, not in solids with some water. The water to be filtered still has roughly the same viscosity as water. Once it becomes more viscous than water they are not suitable.

Yes- we have worked with a number of companies to provide bespoke equipment to solve their filtration problems.
 

Yes, we give a 1-year guarantee on all industrial products.

Normally we can repair it, which is much cheaper than buying a whole new pump.

For use in seawater we can offer all of our mechanical filters in 316 stainless and we fit them with sacrificial aluminium anodes to help prevent galvanic corrosion.

We now also have a range of seawater suitable submersible pumps

Prices for standard items are listed on the Product pages. As there are many options on the products, please ring with your requirements, and we can normally email you a quote within a few hours.

Yes, we often export.

We have distributors in several areas around the world. Check our list of distributors here to find one for your area.

If we don't have a distributor for your area contact us to see if we can export directly to you.

A filter pump is a pump with a filter on the intake; a Rotorflush Filterpump™  is our unique award-winning submersible pump with a built-in self-cleaning filter on the pump intake that keeps the intake filter clear and protects the pump from blocking and clogging.

Pumping what fluid from where to where?

What kind of fluid?

If so, what type of solids, e.g sewage, sand, weed please specify.

What is the maximum and minimum temperature?

If not known, what equipment do you need to protect from suspended solids? 

E.g. valves and nozzles.

What is the minimum aperture size in the system? 

E.g. Whats the smallest nozzle or pipe size?

E.g. litres/second, litres/minute, cubic metres/hour, gallons/minute etc.

If you know it, it would be helpful for us to know your total system pressure requirements including lift, pipe friction losses and any additional pressure required (e.g. pressure at spray nozzles). 

If you don't know, tell us as much as you can about where you want to move the water to and from, and the size of your pipes;we can usually advise.

If so does it have any surplus capacity to power a self cleaning filter? (they normally use 15-25% of the pump’s output).

If you need a submersible pump, do you want the motor to be single phase three phase, 230v or 110v, 50 Hz or 60Hz?
