Single Vane Sewage Pumps

Additional Details

BLAIRS Single vane stainless steel submersible pump / Single Vane Sewage Pumps for professional use, Particularly efficient and reliable in fixed installations with automatic operation with general motor specification and hard-faced mechanical seal. Suitable for pumping liquids containing suspended solids and short fibers. Max. Free passage of Grain size up to Ø 50 mm. Single vane impeller is mounted on the end of the drive shaft and enclosed in a large ring chamber, framed by the pump body and the base. The suction opening is directly linked with the liquid to be pumped, and the rotating impeller is centrifuged in the ring chamber to transmit kinetic energy to the water. Further, the kinetic energy is transformed into pressure energy. Our range of Single vane impellers can also be customized, packaged and delivered as per the client’s requirements. Features: Durable Energy efficient High performance Applications: These pumps are designed to handle dirty water and pumping of liquids containing suspended solids, including short fibers and sewage in domestic and civil applications. It is particularly recommended for the transfer of water mixed with mud in areas such as: domestic housing, industrial applications and underground car parks. This pump is particularly dependable in fixed installations intended for automatic use. A purposely built pit with minimum dimensions 500 x 500 x 500 mm is recommended for fixed installations to give total drainage and to allow correct operation of the automatic float switch. Working Principle: The operating principle is that of pumps with a single vane impeller. This is mounted on the end of the drive shaft and enclosed in a large ring chamber, formed by the pump body and the base. The suction opening is in direct with the liquid to be pumped. The rotating impeller transmits kinetic energy to the liquid, which is centrifuged in the ring chamber, where part of the kinetic energy is transformed into pressure energy. The particular shape of the impeller optimizes efficiency. Performance Range: Flow rate up to 500 I/min.(30m3/h) Head up to 12 m Operating Limits: Fluid temperature up to 50 °C Maximum operating depth 5m below water level Maximum passage for Grain size inlet ˜ 30 mm Structural Characteristics: Pump body: Stainless steel Single vane Impeller: Stainless steel Motor sleeve: Stainless steel Motor base: Stainless steel Motor shaft: Stainless steel Mechanical Seal: Double mechanical seal silicon carbide on the pump side and sealing ring on the motor side (with barrier oil chamber to lubricate and cool the sealing surfaces in the absence of water) Motor: Designed for continuous duty, even with the pump partially submerged (min.250mm) Neoprene H07 RN-F submerged supply cable Construction and safety standards in compliance with EN 60 335-1(IEC 335-1, CE61-150) EN 60034-1(IEC 34-1, CEI 2-3) Type: Con galleggiante with float switch Built-in overload motor protector with automatic reset is incorporated in the single phase model Permanent split capacitor Insulation: Sealed induction motor with double impregnated class F winding(ensuring extended motor life and wide range of use) Protection IP 68
