Qifeng 7.5 HP Submersible Sewage Pump SWQ12.5-50-5.5 Specifications
Powered by a 5.5 kW (7.5 HP) three-phase motor operating at 50 Hz, this Qifeng sewage pump delivers a maximum flow rate of 12.5 m³/h while reaching a maximum delivery head of 50 m, making it suitable for medium-depth lifting in industrial, municipal, and commercial drainage systems. The 2-inch outlet supports efficient discharge, while a 30 mm solid passage allows the pump to handle wastewater containing suspended solids with reduced risk of blockage. Both the pump housing and motor housing are made of cast iron, providing structural stability and resistance to mechanical stress in submerged conditions. The cast iron impeller inside this Qifeng submersible pump ensures consistent hydraulic performance, while the stainless steel 304 shaft improves resistance to corrosion and wear over long operating cycles. Sealing is handled by a graphite/ceramic mechanical seal, a practical combination for sewage environments where reliability under continuous operation is essential. The pump is rated for liquids up to 40 °C, covering most standard wastewater and sewage transfer applications. Depending on installation requirements, the unit can be supplied with or without a floater, for automatic level control. Overall, the SWQ12.5-50-5.5 is a balanced choice for users who need controlled flow, solid-handling capability, and durable construction all in a compact submersible sewage pump design.
