The 250WQ680-42-132KW-4 is a heavy-duty cast iron submersible sewage pump engineered for high-flow and high-head wastewater applications. Featuring a 132 kW, 4-pole motor configured for 440V, 50Hz industrial power supply, this pump delivers a design flow rate of 680 m³/h and design head of 42 m with a DN250 discharge outlet.

Ideal for municipal sewage systems, industrial wastewater transfer, sewage lift stations, construction drainage, mining operations, and large-scale water treatment projects.

• High Flow Capacity: 680 m³/h for efficient transfer of large sewage volumes in lift stations, collection tanks, and emergency dewatering
• 42 Metre Design Head: Supports applications with significant lifting height or long discharge pipelines
• 132 kW 4-Pole Motor: Stable performance for demanding wastewater applications with 440V, 50Hz industrial power supply
• Durable Cast Iron Construction: Mechanical strength and wear resistance for standard sewage conditions
• Compact Submersible Installation: Operates directly in wet wells with optional auto-coupling for easy maintenance
• Engineered for Industrial Applications: Hydraulic design reduces clogging risk and supports efficient wastewater transfer

Before ordering, please provide required flow rate, total dynamic head, liquid composition, maximum solid size, liquid temperature, installation depth, pipe size, and available power supply.

For wastewater containing long fibres, large solids, concentrated sludge, or corrosive chemicals, provide details in advance to verify impeller type, solids passage, sealing arrangement, and material selection.

The pump should not operate continuously far from its recommended duty point. Correctly matching the pump curve to the system curve improves energy efficiency and extends service life of bearings and mechanical seals.

For price, performance curve, dimensional drawing, delivery time, or selection support, please provide:

• Required flow rate and head
• Liquid composition and solid content
• Voltage and frequency
• Installation method
• Required quantity and project location

Our technical team will verify pump and accessory configuration according to your operating conditions.
