Vertical sump pumps are intended for use in the industrial pumping applications to pump clean or lightly contaminated liquids, fibrous slurries and liquids containing large solids from the deep sumps. The pumping head is suspended into the pumped liquids and the drive motor is dry installed on the top.
The pump has separate discharge pipe and support pipe column. The vertical sump pump has a vertical line shaft with slide bearings or cantilever design without slide bearings.
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 rotating assembly. Unique space-saving design due to vertical mounting of pump. Impeller and casing are totally submerged in liquid so no priming or air venting is required. Inside tank and outside tank mounting designs available for respective applications. It is virtually maintenance free. Vertical pumps are best suited for wet pit applications where fluctuations in liquid levels are considerable. The pump unit is suspended by a column pipe which also protects the transmission shaft and is submerged in the liquid to be pumped. These pumps require small floor area and can be started without priming.
Special Features
- Vertical pumps take little space in plan since the liquid is led away to the axis of shaft.
- The impeller is submerged, so pump does not require to be primed and is always ready for use.
- The positive suction condition also prevents the cavitation in the pump and pitting in impeller and diffuser.
- Due to positive head at suction the pump gives its rated performance as well as high overall efficiency whereas in horizontal pumps due to losses in suction line, foot valve etc. the rated performance of the pumps is not achieved
Applications
Dewatering applications where water is contaminated with solid particles. - Raw sewage, slurry. - Effluent, industrial waste transfer in industries (Thermal Power, Steel, Cement, Chemical, Sugar, Oil). Waste water management in hotels, hospitals, malls and housing societies. - Drainage of basements, tunnels, boiler rooms. - Storm water.
Salient Features
Compact design, easy to install, The impeller is submerged, so pump does not require to be primed and is always ready for use. - The positive suction condition also prevents the cavitation in the pump and pitting impeller and diffuser. Closed type and semi-open type impeller designs are offered based on application.
