Product Overview
Internal fluid velocity paths and hydraulic behavior for the SEV.65.65.40.A.Ex.2.50B utilize a SuperVortex configuration to manage contaminated liquids. This submersible pump addresses the requirements of municipal wastewater networks and sewage collection systems where grey water with a pH range of 4 to 10 is present. The unit is intended for wastewater transfer and effluent management in collection pits. It maintains stable operation in dry or submerged installations prone to varying fluid ingress and temperatures up to 40°C to support sub-surface infrastructure and pump stations.
Hydraulic performance is driven by a 4 kW motor on a 415v three-phase supply, generating a maximum flow of 1002 L/Min. This model achieves a maximum total head of 29.6 m, making it suitable for discharge in pressurized sewer mains and treatment plant transfer duties. Operating with a rated current of 8.2 Amps at 2925 rpm, the unit maintains consistent torque for processing fluids in drainage stations. Rapid evacuation is achieved through the DN 65 discharge port using a 10-metre power cable for secure electrical distribution.
Internal centrifugal design utilizes a SuperVortex impeller to facilitate the passage of solids up to 65 mm in diameter without internal clogging. This configuration handles wastewater in suspension, maintaining volumetric efficiency throughout prolonged service cycles. By utilizing a vortex flow path, the unit minimizes internal vibration and friction to protect the rotating assembly during grey water handling. The impeller configuration is intended for liquids containing soft solids and organic materials in municipal and industrial wastewater handling.
Mechanical stability is achieved through a heavy-duty cast iron housing and motor shell with an IP68 protection rating for permanent dry or submerged installations. The motor is shielded by a double mechanical shaft seal in an oil bath, utilizing a SiC/SiC primary seal for abrasive resistance and a CER/CARNBR secondary seal. This A-version model features an Ex-rated motor with integrated moisture and water-in-oil sensors for fault detection. The assembly includes a DN 80 inlet for integration into wastewater collection systems.
Features

To prevent vault surcharge during floods, what peak volumetric displacement is achieved?
High-load pumping duties see Grundfos SEV.65.65.40.A.Ex.2.50B displace a peak fluid volume of 1002 L/Min.
To elevate effluent into high plant headers, what maximum discharge head is maintained?
Maximum fluid lift reaches 29.6 m under full motor load with SEV.65.65.40.A.Ex.2.50B.
At full electrical loading, what motor kilowatt rating, operational line voltage, and full-load current drive this heavy pump?
Plant power systems supply SEV-65-65-40-A-Ex-2-50B across a three-phase 415 V connection to drive a 4 kW motor at 8.2 Amps.
Evaluating particulate clearance, what spherical passage dimension accommodates raw effluent across this high-head vortex pump?
Sump blockages are prevented by SEV 65 65 40 A Ex 2 50B through a 65 mm spherical through-let built into its SuperVortex casing.
Simplifying routine inspections, what guide rail auto-coupling arrangement simplifies hoist servicing in municipal sewer wells?
Pressure-tight discharge mating is provided for SEV/65/65/40/A/Ex/2/50B through an integrated auto-coupling flange and pedestal.
