Structural stability in sewage collection systems and municipal networks is provided by the cast iron housing and motor shell of the SEV.65.80.40.2.50B. This submersible pump addresses wastewater removal requirements for contaminated grey water with a pH value between 4 and 10. This unit is intended for drainage stations and wastewater transfer duties where reliable solids passage and continuous operation are necessary. The system maintains stable performance in dry or submerged installations prone to varying fluid ingress and temperatures up to 40°C.
Hydraulic capacity is provided by a 4 kW motor operating on a 415v three-phase supply with a rated current of 8.2 Amps. This assembly generates a maximum flow of 1002 L/Min and achieves a maximum head of 28.8 m for pressurized sewer mains or gravity drainage. The motor operates at a synchronous speed of 2925 rpm, ensuring consistent pressure behavior and circulation characteristics during service cycles. Power is distributed through a 15-metre Lyniflex cable to support sub-surface infrastructure and treatment plant transfer duties.
Internal centrifugal design utilizes a SuperVortex impeller configuration to facilitate the passage of solids in suspension. This design handles particles up to 65 mm in diameter, preventing the internal clogging that could otherwise compromise volumetric efficiency. By utilizing a vortex flow path, the unit minimizes internal friction and vibration to protect the rotating assembly during prolonged service. The impeller handles liquids containing organic materials without internal clogging to maintain operational flow behavior in municipal collection pits.
Mechanical integrity is reinforced by an IP68 enclosure rating for protection against environmental contamination. Motor protection is anchored by a double mechanical shaft seal arrangement featuring a SiC/SiC primary seal and CER/CARNBR secondary seal in an oil bath. The casting includes a DN 80 inlet and DN 80 outlet connection for integration into standard wastewater infrastructure and lift stations. The architectural design features a stable base for firm positioning in subsurface drainage networks and effluent transfer systems.
Features
- SuperVortex impeller configuration facilitates the passage of solids up to 65 mm without internal clogging.
