The answer to Blocked Filters... The self cleaning Rotorflush filter is completely cleaned every ½ second keeping any solids away from the filter screen, preventing them entering the system. The very efficient self cleaning action allows fine filter meshes to be fitted without fear of blocking.
These are high quality submersible pumps with their own integral self cleaning intake filters.This allows the high pressure, multi stage pumps to work in water contaminated with suspended solids and produce water filtered from 50-315 microns (depending on application) for use in upstream equipment preventing nozzle blockage and solenoid valve blockages. Rotorflush Filterpump model N9516 See Rotorflush Submersible Self Cleaning Filterpump details Applications: Filterpump uses: Potable water or final effluent is often used for washdown of inlet screens at sewage works. Recycling of screened sewage or final effluent is often not possible for this purpose without filtration or valves and nozzles will quickly block. Traditional self cleaning filters can be expensive and do not protect the pump from solids. The Rotorflush Filter Pump with a 315 micron self cleaning inlet screen can be used with raw sewage, screened sewage and final effluent to provide recycled water for washdown of inlet screens that will not block nozzles or solenoid valves. The all stainless steel construction and high head performance of this pump makes it an easily installed and reliable pump and self cleaning strainer for water recycling. Water Monitoring Instrumentation Filters Online instruments and analyzers are becoming increasingly used to constantly monitor water, wastewater and final effluent quality. They normally work well if supplied with a fluid relatively free from suspended solids.However many effluent streams contain levels of suspended solids which need to be filtered out. Most filter systems need constant maintenance, cleaning screens and filters or replacing filter cartridges. The Rotorflush Filterpump with its self cleaning inlet strainer provides a simple cost effective solution in one product. Simply mount the Filterpump in the effluent stream and a screened supply of liquid is continuously supplied to your analyser, with no maintenance or consumables. Screens are available with apertures from 50 microns to 315 microns. Instrumentation Filters for the Pulp & Paper Industry Anyone working in the pulp and paper industry knows that white water is extremely difficult liquid to filter owing to the large quantity of fibre and clay. We have spent several years developing an automatic self cleaning filter system specifically to filter white water to 33 microns, enabling the output to supply analyzers without blocking the cells. Output of the system is 1-2 litres/minute. Please call us for more details As an Agricultural Low Rate Irrigation pump for dirty water systems. Dairy and Pig farms usually have several settlement tanks to collect the dirty water that is produced by the livestock unit. Some of the solids settle, but some are nearly the same density as water and do not settle out quickly enough. Nearly always there is a small pump to pump the partially settled effluent up a pipeline to be irrigated on the fields. A number of problems frequently occur with these systems. If a suction filter is provided on the pump inlet, this often blocks. If no filter is provided, the pump, pipeline or irrigator nozzles will often block. Surface mounted multi stage centrifugal or progressive cavity pumps are usually used.These require a pump house and frost protection and a float switch. The Rotorflush Filter pump, is a submersible pump with an integral self cleaning suction strainer with built in float switch, it does not require a pump house or frost protection. The self cleaning inlet filter requires little maintenance and protects the pump, pipelines and irrigator nozzles from blockage.The fine filter screen stops the majority of weed seeds from being sprayed on the field causing weed problems. For existing agricultural dirty water pumps, the RF200R and RF400R filters are specifically designed for surface mounted centrifugal and progressive cavity pumps. On Farms for De-Watering Slurry Lagoons Slurry Lagoons often contain more water than manure and this causes major problems when it comes to cleaning them out. Transporting water by vaccy tanker is expensive in machinery and time and is bad for soil structure in wet conditions. A Rotorflush Filterpump fitted with a control valve when sited in the lagoon will pump a large proportion of the water out leaving the solids behind. It can either be pumped into the dirty water system or with one of our high pressure pumps straight out to an irrigator. Fountains and Water Features Fountain pumps usually have a fine inlet filter to stop the pump and the fountain head blocking with debris. These inlet screens often need cleaning, particularly in the summer when weed and algae growth is at its highest. The Rotorflush Filterpumps with their self cleaning inlet screens, protect the pump and fountains from blocking and need very little maintenance. Another major advantage is that owing to the very fine self cleaning inlet screens tadpoles and small fish are not sucked into the pump, preserving the aquatic life in the pond. Our Low Head Filterpump models are ideal for this purpose and we can provide them with floats and fountain heads if required.
