Product Overview
Sewage transfer stations and industrial wastewater collection networks frequently install this ductile iron submersible sewage pump for high-capacity submerged operation. Untreated effluents and raw sewage containing large solids are moved reliably through large-scale utility infrastructure.
Flow capacity reaches 23880 L/min with a maximum head of 25.5 m, powered by a 50 kW motor. The 8-pole motor operates at 726 rpm on a 415 V three-phase supply, drawing 98 Amps for consistent torque delivery during peak collection periods.
A ductile iron 2-channel impeller with 105 mm solids passage prevents internal clogging by allowing large particles and organic contaminants to pass safely. The optimized flow path maintains steady circulation even with highly contaminated wastewater.
Ductile cast iron construction with IP68 enclosure and Class F insulation provides maximum submerged durability. SiC/SiC shaft seals and integrated moisture sensors protect against liquid ingress. Supplied with a 15 m power cable and rated for depths up to 20 m.
FEATURES
- 2-Channel Ductile Iron Impeller: High-volume displacement with reliable solids handling.
- 105 mm Solids Passage: Extra-wide clearance for untreated sewage and large contaminants.
- IP68 Enclosure: Fully sealed for permanent submerged operation.
- Ductile Cast Iron Construction: Enhanced structural strength and wear resistance.
- SiC/SiC Mechanical Shaft Seals: Durable barrier against moisture ingress.
- Active Moisture Sensing: Real-time monitoring with early warning protection.
- 50 kW Motor: Consistent performance at 726 rpm.
- Star/Delta Starting: Reduces stress and power surges during startup.
