Multicyclone Prefilter

The Multicyclone is a pre-filter that is used in conjunction with a sand filter to reduce the backwashing frequency and to extend the life of the sand filter's media. The Multicyclone Plus has all the benefits of the ever popular Multicyclone with the addition of a 40ft2 cartridge filter located in the upper housing. Incoming water enters the hydrocyclones tangentially, generating a strong centrifugal effect. The sediment particles are then spun out to the hydro cyclone's wall and spiral down into the sediment chamber. The filtered water then migrates towards the centre of the hydrocyclone where the water reserves and spirals upwards and through a 40ft2 cartridge element before exiting the Multicyclone Plus. The addition of the cartridge element provides the highest standard of filtration possible with very little need for cleaning. The majority of the sediment is removed by the hydrocylones. The sediment level can be visually monitored through the Multicyclone's clear sediment bowl. The pressure gauge located at the top of the unit indicates when the cartridge requires cleaning. The cartridge can easily be removed by undoing the locking ring.The Multicyclone is cleaned by simply opening the purge valve. Only 15 litres of water is discharged to clean the MultiCyclone of sediment.

Filter Media

There is a variety of filtration media available including sand, glass, gravel, diatomaceous earth and Zeoclere (zeolitic media). Ensure that the filter media selected is suitable for the filter and the application.ZeoclereThis filter media gives years of service along with water clarity 60% better than sand. It is ideal for leisure centre, school, hotel, and hydrotherapy pools. A straight swap from sand, Zeoclere removes ammonia and heavy metals from pool water. It has achieved NSF61 - NSF50 - NSF50ii certification.Glass Bead Filter MediaGrade 1 glass beads have a small effective size of only 0.6mm to 0.8mm. Its narrow particle size range allows in-depth filtration and extends operating cycles between backwashing. They have been laboratory tested to be able to effectively filter down to below 3 microns and are spherical and do not have any sharp edges. They are safe to handle and safe to service and are manufactured from 100% virgin glass and are chemically inert.The spherical smooth shape results in a low co-efficient of friction reducing its backwash water requirements and backwash with up to 20% less waterthan sand, saving time and water. Glass beads are easy to install and enable a rapid start-up of the media filter. It high purity means very little backwashing is required to cleanse the filter media prior to commissioning the filter. Certikin Glass Filter MediaThis environmentally friendly filter media is made from a glass recycled in the UK. It is a viable alternative to sand and does not involve intrusive mining and the use of scarce resources. It is available in three grades - all grades are milled down to remove sharp points and are packed in 25kg bags.Glass media is more efficient than sand as it can remove up to 30% more material and pollutants than sand so saving on backwashing and the resultant water, energy and chemical treatment costs. It doesn't degrade so has a longer life span.Use in place of traditional filter media. Grade 1 is equivalent to 16/30 grade sand; Grade 2 is equivalent to 8/16 grade sand; Grade 3 is equivalent to 6mm gravel.

OC-1 Filtration Media

Unlike traditional methods that use entrapment, OC-1 works through settlement and harnesses advances in pump technology and variable speed pumps/controllers. The new British manufactured filtration media has some exceptional benefits - by replacing commonly used media (such as sand and glass) with OC-1 it is possible to reduce the head loss in the filtration system; filter with a constant flow (regardless of debris entrapment) and, most remarkably, significantly reduce running energy costs whilst still filtering to the equivalent standard as it can be used with a smaller pump or a variable speed pump or controller.Why YOU should switch to OC-1- Reduces energy consumption – OC-1 maintains constant flow rates, even when the media becomes dirty. No downtime is required for heating/salt chlorinators/heat pumps going out on low flow. The constant flow means pumps can be run at lower speeds, thus saving energy. - Huge capacity for debris collection – OC-1 offers over 20 times the capacity of sand or glass. - Reduced requirement for backwashing and a more efficient backwash - Reduces water consumption, chemical usage and heating. - Lightweight - Can even be shipped inside a filter, easy to handle and super quick and easy to install. - Less Maintenance - lasts longer than sand, reduces pressure in the system, extending the life of equipment. - Filters to International swimming pool standards. - Recyclable at end of product life. - Payback typically 12-18 months.

Pressure Gauges

This selection of pressure gauges each have a 0.25 male BSP thread."

Multiport Valves

Our multiport valve selection includes models for most current domestic swimming pool filters. Which valve should I use-First identify the type (brand) of filter that you require the valve for. Is the valve mounted to the side of the filter (side mount) or does it attach directly to the top of the filter (top mount)- Next establish the size of the pipework connections to the valve. With this information, you will then be able to select the correct valve from the list shown.

Besgo Automatic Backwash Valve C/W Sol…

Manufactured in Switzerland, the Besgo valve is a hydraulic drive system controlled by a single 240v solenoid. When powered, the valve opens and forces the hydraulic system into an alternative position, directing water through a different route. Activate the solenoid again and the system will return to its original state, thus providing automated switching from filtration to backwash and vice versa.Features- 3 to 5 bar mains water pressure or compressed air required to actuate the system- The solenoid can be controlled by several methods. E.g. timed, pressure, manual etc.- In the event of power failure the valve remains in its closed position (normal filtration) therefore preventing accidental emptying of the pool.- Closed in less than 2 seconds- Silent operation- No pressure hammer- Low pressure loss- With power failure valve is shut- No need to turn the pump off- Control panel available with backwash programme capability

Besgo 3 Way Valve

3-way valve When used with the backwash valve it will provide an added rinse facility after backwash An alternative use is for automated switching if water supply between applications e.g. two water features sharing one pump.
