What Pump Suction Filters Do
Pump Suction Filters are essential for maintaining the efficiency and longevity of water pumps by preventing blockages caused by debris, weeds, or particulates in the water, which can lead to pump failure and costly downtime and reduce or stop the flow of water.
The filter mesh size must match the pump’s clearance to effectively prevent blockages while minimizing impact on other connected equipment, such as irrigation nozzles or heat exchangers, which may have lower particulate tolerance.
Traditional intake filters, basket filters or coarse pump suction filters can protect pumps but may also require frequent maintaining as they too may block ahead of the pump. Unlike traditional filters, Rotorflush high-quality Pump Suction Filters feature self-cleaning capabilities, reducing the need for frequent maintenance and ensuring uninterrupted operation.
Types of Pump Suction Filters
There are two main types of Pump Suction Filters, each designed for specific pump setups:
Pump Suction Filters for Dry Mounted Pumps: These pumps typically employ Pump Suction Filters attached to the end of a suction hose submerged in the water source. These filters are akin to basket strainers and are prone to blockages if the water source contains debris and other solids. A self-cleaning suction filter is particularly beneficial to prevent frequent clogging.
Pump Suction Filters for Submersible Pumps: Submersible pumps usually have a filter or strainer around their intake, safeguarding the pump’s impeller set from damage and clogging. Given their compact design, these filters can easily become obstructed by large debris like leaves, necessitating regular cleaning unless equipped with a self-cleaning system.
Environmental Considerations
When abstracting water from natural sources, Pump Suction Filters often need to comply with regulations to protect aquatic life. These regulations dictate the need for specific sized screening and intake velocities to safeguard fish and eel populations. The small screen size prevents fish fry and glass eels from becoming entrained in intakes and pipework, while a low intake velocity allows them to escape being trapped on the intake screen.
Pump suction aperture sizes for eel and fish screening are typically 2 mm or less, very difficult to keep clear if there is any weed, leaf litter, rubbish or other debris in the water unless the screens have some self-cleaning capability
Rotorflush’s Innovative Solutions
While Pump Suction Filters protect against pump damage, they can also block, leading to downtime and increased maintenance costs. Opting for self-cleaning Pump Suction Filters significantly reduces these issues by prolonging maintenance intervals and ensuring continuous operation.
Rotorflush Filters provide a range of robust, self-cleaning Pump Suction Filters designed to operate efficiently in contaminated water. Crafted from durable stainless steel, these filters feature a continuous backwash system that keeps the mesh clear, expelling debris and solids. These filters are widely used in the Water Industry and Agricultural sectors.
Additionally, Rotorflush offers submersible pumps with integrated self-cleaning Pump Suction Filters, ensuring long maintenance intervals even in challenging conditions. All Rotorflush products can be tailored to meet environmental standards for fish and eel screening, making them a reliable choice for sustainable water management.
