Sump pumps are vercally suspended single casing pumps with separated discharge, semi open or enclosed impeller designed for wet pit applicaons. They are designed to provide dependable, economical drainage service on medium capacity installaons in commercial buildings and general industrial applicaons. Closed type and semi-open type impeller designs are offered to handle a variety of liquids. Impeller and casing are designed for maximum hydraulic efficiency and minimum thrust on rotang assembly. Unique space-saving design due to vercal mounng of pump. Impeller and casing are totally submerged in liquid so no priming or air venng is required. Inside tank and outside tank mounng The impeller is submerged, so pump does not require to be primed and is always ready for use. The posive sucon condion also prevents the cavitaon in the pump and ping in impeller and diffuser. Due to posive head at sucon the pump gives its rated performance as well as high overall efficiency whereas in horizontal pumps due to losses in sucon line, foot valve etc. the rated performance of the pumps is not achieved. Vercal pumps take lile space in plan since the liquid is led away to the axis of sha. Delivery Casing : The delivery casing has an area sufficient enough to ensure easy passage of liquid with opmum efficiency. Impeller: Impellers are enclosed / semi-open / open with large passage ways and thickened vanes at the inlet. All impellers are dynamically balanced. Pump Sha : The pump shas are of high tensile carbon steel and designed for high torque transmission. Stainless steel shas can be provided against requirement. The bearing areas are protected by stainless steel sleeves. Intermediate, line and head shas are of ample strength and rigidity. Minimum bearing span is adopted to keep deflecon and vibraon to a minimum. Line Sha / Intermediate Sha : Line shas / intermediate sha of high tensile carbon steel designed for high power transmission are connected by intermediate couplings and run in closely spaced bearings for vibraon-free operaon. VERTICAL SUMP PUMP designs available for respecve applicaons. Very rigid construcon with extra wall-thickness provided for corrosive applicaons. It is virtually maintenance free. Vercal pumps are best suited for wet pit applicaons
