Single Vane Sewage Pump

BLAIRS Single vane stainless steel submersible pump for professional use. particularly efficient and reliable in fixed installations with automatic operation with general motor specification and hard-faced mechanical seal. pump are highly efficiency pumps for professional use & built completely in stainless steel. They are extremely reliable and suitable for continuo's duty. 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 direct with the liquid to be pumped. The rotating impeller which is centrifuged in the ring chamber transmits kinetic energy to the water; kinetic energy is transformed into pressure energy. The particular shape of the impeller optimizes efficiency. Max. Free passage of Grain size up to Ø 50 mm.

APPLICATION

Single Vane Sewage Pump BLAIRS single vane submersible pump is designed to handle dirty water for pumping 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. in a purposely built pit with minimum dimensions 500x500x500 mm is recommended for fixed installations to give total drainage and to allow correct operation of the automatic float switch.
