Water Irrigation Pumps and Filters
Dirty Water Irrigation Filters and Pumps Invented on a Dairy Farm
The award-winning Rotorflush Self-cleaning filter system has its origins in Irrigation for agriculture. The first strainers and screens were developed specifically to return dirty water on dairy farms back to land - no one wants to tanker dirty water away.
Irrigation Pumps and Irrigation Pump Strainers
Rotorflush self-cleaning irrigation water intakes and filter pumps help keep irrigation equipment clear from blockage by weed and other water-borne debris, reducing maintenance and downtime. Irrigation companies love our self-cleaning filters - good for crops, golf courses, garden centres and good for their customers.
Crop Irrigation
Irrigating Crops
Irrigating crops involves the controlled application of water to agricultural land to ensure optimal growth and yield. Water can be sourced from groundwater from wells or springs, and from surface water inrivers, lakes, or reservoirs.
Irrigation Methods
Irrigation systems typically take water from lakes, rivers and ponds. River or lake irrigation systems are sensitive to water quality - water for irrigation can contain weed and debris that clogs irrigation pumps and interrupst irrigation systems. Irrigation pump filters and submersible irrigation pumps with self-cleaning intake screens will help to keep water irrigation equipment clear when using these methods to irrigate:
- Sprinkler Irrigation: Water covers large areas efficiently through overhead high-pressure sprinklers.
- Drip Irrigation: directly waters crops root zone through a network of pipes with emitters.
Both of methods need screened water to keep the small aperture nozzles and emitters clear and unblocked.
Self-cleaning Filtration for Irrigation
Farmers worldwide use Rotorflush self-cleaning irrigation water intake screens on their pump suction intake pipes. The screens prevent debris from entering the irrigation system. Their self-cleaning mechanism keeps the intake screen clear for low maintenance.
Some farmers choose to use Rotorflush Filterpumps™ in place of a pump with a separate irrigation pump strainer, and to keep water flowing and down-time to a minimum.
Irrigation for Parks and Golf Courses
Keeping public spaces and golf courses looking their best requires a keen weather eye and precision watering.
Typically, this involves using advanced irrigation systems that deliver water precisely based on soil type, grass species, and micro-climates. Irrigation personnel will customize watering schedules to optimize turf health while minimizing water wastage, and schedule watering during optimal times (early morning or late evening) to reduce evaporation.
They will aim to ensure an even distribution of nutrients through well-designed irrigation systems, promoting robust growth and resilience against stressors. Consistent irrigation practices will obtain uniform colour and texture across the golf course and landscape.
Adopting irrigation practices that emphasize water conservation, and utilising sustainable water sources where possible keep running costs down and efficiency up. Water sources are all important in meeting this aim. Rainwater harvesting lagoons or tanks, or a natural water source - a river, pond or lake - are ideal.
Irrigation should be as low maintenance and hassle-free as possible to meet these exacting requirements. Good water management, screening and filtering to avoid interruptions to the schedule or loss of ground coverage is essential.
Who Uses Rotorflush Self-Cleaning Filtration to Protect Their Irrigation Equipment?
Water conservation, recycling and ease of use are high on the list of our customers' irrigation priorities. That's why South Wales Sports Grounds use one of our filterpumps; Garden Centres including Dobbies, Knights and Groves buy Rotorflush. Golf courses as far apart as Parley in Bournemouth, Plzensky in the Czech Republic, Markisher in Germany and Sidcup Golf club chose our filtration products to meet their irrigation needs.
Using Rotorflush Products in Water Irrigation Systems
All Rotorflush products are designed for use on pump suction; our filter pumps have a self-cleaning screen on the pump intake and our self-cleaning basket strainers and filters connect to the suction pipe of surface mounted pumps.
Drawing water for irrigating crops, lawns, golf courses, or for flooding or draining wetlands can be problematic. Even the cleanest raw water can contain weed and debris that may block pumps and the drip feeds and nozzles of irrigation equipment. Clearing blockages is time-consuming and costly.
Our filter pumps allow water to be pumped and screened at source. The self-cleaning inlet filter requires little maintenance and protects the pump, pipelines and irrigation nozzles from clogging.
For surface mounted agricultural dirty water pumps, our RF200R and RF400R filters can be fitted to suction intakes. They are specifically designed for surface mounted centrifugal and progressive cavity pumps. Again, the self-cleaning mechanism keeps the filter mesh clear whenever the pump is in operation. Find out more about these self-cleaning strainers and filters.
The Best Irrigation Pump Strainers and Intake Screens
Not all irrigation systems and applications are suited to the use of submersible pumps. Dry mounted pumps are often used - the suction intake hose drawing directly from the water source.
Preventing the pump, and as just importantly, the irrigation lines, feeds and nozzles from blocking requires irrigation filters on your pump intake. Rotorflush manufacture ranges of self-cleaning suction intake filters, strainers and screens for use with dry mounted pumps. These self-cleaning irrigation intakes can screen out particulate down to 60 microns and cover a wide range of flow rates and capacities. Irrigation made easy.
Frequently Asked Questions
Rotorflush self-cleaning filtration products are used for separating solids from dirty and contaminated water so that pumps, spray bars, irrigation and other equipment does not block or clog. Typical uses are:
- Screening and pumping water from lakes, ponds and rivers
- Screening and pumping dairy run-off from lagoons or settlement tanks
- Filtering water ahead of irrigation equipment
- Complying with Eel regulations when abstracting raw water
All of our self-cleaning intake screens are specified to suit required flow rates, for instance filter pumps are recommended based on the flow rate and pressure your system needs and intake strainers and screens are specified according to the maximum flow through that is required.
Consideration should be given to what mesh size you need - top tip, go for the largest mesh size you can get away with to minimise maintenance. This will be determined by the smallest aperture the water you are drawing needs to go through, for example a 3 mm irrigation nozzle or spray bar aperture.
If you need advice or more information please get in touch.
Increasingly, the Environment Agency makes taking steps to protect eels a condition of abstraction licences in England and Wales. These environmental regulations may have a bearing on the type of filter pump or strainer you need.
Our Products can be sized to account for Eel Regulations or EPA rule 316(b) if applicable, so that intake velocity and mesh size meet regulatory requirements for the flow rate you require.
Use of our products in sludge from bio-digesters, raw sewage or livestock slurry is not recommended.
Our strainers and filter pumps are ideal where the medium is dirty water contaminated with organic and fibrous particulate but only so long as the liquid is equal to or very near the viscosity of water.
Animal slurry and bio-digestate are too thick and concentrated for our self-cleaning screens to work effectively.
Not every submersible pump is suitable to be turned into a filter pump.
When we manufacture a filter pump we re-engineer the pump to have an additional impeller to provide the wash water to the screen without sacrificing the output of the pump.
Re-engineering a pump can often invalidate its warranty. Therefore, we would highly recommend that you opt for one of our Filterpumps™ that come with their own 1-year warranty.
If however you have a particular pump that you would like to be made into a filter pump, please contact us to discuss.
Yes – because our products pump and filter directly from a dirty water source, there is less need for expensive in-line filtration. All our products have built-in self-cleaning back-washes that prevent intake screens from blocking, keep pumps clear and protect other connected equipment. This reduces maintenance, minimises downtime and can extend the life of pumps.
The Best Submersible Irrigation Pumps
The Best Submersible Irrigation Pumps are those that require the least maintenance. Rotorflush continuously rated submersible centrifugal irrigation pumps are designed to screen water as they pump.
Their integral self-cleaning pump suction intake screen automatically backwashes to prevent blocking at the intake - all your other irrigation equipment is also protected from debris and particulate that might otherwise clog your irrigation system.
