Vertical Sump Pump
Sump pumps are vertically suspended single casing pumps with separated discharge, semi open or enclosed impeller designed for wet pit applications. They are designed to provide dependable, economical drainage service on medium capacity installations in commercial buildings and general industrial applications. 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. Very rigid construction with extra wall-thickness provided for
corrosive 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. Discharge / Suction flanges conforms to ASA / DIN / BS standards.
High Efficiency
Heavy Duty
Adaptability
Less Noise
- 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.
- Delivery Casing : The delivery casing has an area sufficient enough to ensure easy passage of liquid with optimum efficiency.
- Impeller: Impellers are enclosed / semi-open / open with large passage ways and thickened vanes at the inlet. All impellers are dynamically balanced.
- Pump Shaft : The pump shafts are of high tensile carbon steel and designed for high torque transmission. Stainless steel shafts can be provided against requirement. The bearing areas are protected by stainless steel sleeves. Intermediate, line and head shafts are of ample strength and rigidity. Minimum bearing span is adopted to keep deflection and vibration to a minimum.
- Line Shaft / Intermediate Shaft : Line shafts / intermediate shaft of high tensile carbon steel designed for high power transmission are connected by intermediate couplings and run in closely spaced bearings for vibration-free operation.
- Stuffing Box : Fitted at support plate level comprising five packings and a lantern ring. Grease sealing by water / liquid optional.Mechanical seal instead of packings can be offered against specific requirement.
- Motor Stool : The heavy duty cast iron / mild steel motor stool is capable of taking the motor and rotor assembly weights as well as the axial thrust. It also houses the thrust bearings.
- Thrust Bearing Assembly : An anti-friction thrust bearing located in the motor stool and lubricated by grease is capable of taking the dead weight of the rotor and axial thrust. A sleeve bearing is fitted below the thrust bearing and is also grease lubricated.The bearing nut and bearing lock nut are easily accessible and serve to adjust the axial position of the rotor unit such that the clearance between impeller and casing can be adjusted.
- Delivery Pipe : Heavy duty delivery pipe upto the motor stool floor level with one bend is standard supply with all.
