Bestway Flowclear 800 Gallon Filter Pump can help keep your water clean and clear of debris. Filter cartridge pumps are an economical and convenient way to keep your pool water clean and are so simple to set up. The 800 gal Flowclear Filter pump comes with a 4.2 inch by 5.4 inch filter cartridge that can be simply and easily replaced. Even if you are swimming in your pool every day, a cartridge will last a minimum of two weeks and much longer if you keep your pool covered and protected. Once the pump is connected to the pool and the filter system, the pump can push through 580 gal of water per hour (2, 195L/hr system flow rate). This integrated system flow rate makes the 800 gal pump perfect for Bestway pools with a volume of 300-4, 600 gallons such as large Steel Frame, Hydrium and Fast Set Pools.
