WQ-4P/6P Submersible Cast iron Sewage Pump

The WQ series pumps are basic submersible sewage pumps with channel impellers. There is a wide product lineup that can be easily installed in combination with auto-coupling rail systems or use free-standing with a flexible hose or flange connection. With excellent reliability and durability, the pump must be completely submerged in water when working. It can run continuously for a long time. Therefore, they contribute to stable equipment operation in pumping stations and water treatment plants, and help greatly reduce maintenance costs.These pumps have been actively used in many water treatment plants, pumping stations, flood control facilities and water parks. When manufactured according to GRANDFAR’s unique seawater-resistant specifications, these pumps can be reliably used to draw seawater from shipyards and power plants. In short, the WQ series reflects our years of experience and expertise, so it can be applied to various fields and applications.
