SUBMERSIBLE DRAIN PUMP MODEL NO.- VSJ
 
Delivery Pipe Size up to –1 50mm(6”)
Capacity upto - 5500 LPM
Head upto - 53 M
H.P. up to - 30 HP
“VSJ” Pumps are portable and no installation work. As soon as the impeller is submerged, the pumps are ready to work. They can handle fresh water, water heavily contaminated with sand, gravel and sludge. The pumps can work unattended when fitted with level controllers.
APPLICATION :-
These Pumps are extremely useful in :
Construction sites
Mines.
Deep excavations
Draining Pits
Thermal Plants
Industrial waste
Marine vessels
CONSTRUCTION FEATURES :-
VERTICAL MONO – BLOCK TYPE DESIGN
The heavy-duty shaft is mounted on two extra heavy bearings for minimum defection. Entire rotating assembly is dynamically balanced and impeller is hydraulically balanced to reduce axial thrust on bearings, thereby preventing vibration to a minimum level. The discharge being axially upward there is no unbalanced load on the sides. These Drain Pumps have a solid base plate, which prevents upsets and guards against the pump digging itself into hole.
UNIQUE FEATURES :-
These unique features make these submersible drain pumps most suitable and reliable for all dewatering and drainage operations, containing solids.
DUAL PROTECTION AGAINST WATER LEAKAGE:
Pumps are fitted with two independent mechanical seals for dual protection against pump failure. The lower seal prevents water from entering the seal chamber. The upper seal provides additional protection to the motor against water seepage, in spite of the failure of the lower seal. PVC insulated winding wires also protect the motor in case of water seepage.
COOLING APRANGEMENT :-
Cooling of the motor has been given top priority in the design of these pump sets, thereby making them capable of continuous operation for long time.
The entire Pump and Motor bodies are made of best quality aluminum alloys up to 10 HP Model having very high heat conductivity.
The Pump discharged liquid flows through the annular space between the motor body and the outer jacket thus absorbing & dissipating the heat generated by the motor.
Both the motor chamber and the seal chamber being oil filled rapid cooling of the motor is assured. The oil also lubricates the bearing and the seal faces, while the pump is working.
HIGH PRESSURE ZONE :-
Submersible drains pumps are specially designed to create automatically a high pressure zone inside the motor for preventing any leakage water entering the inside of the motor while operating the pump set .
CORROSION PREVENTION :-
All components of the submersible drain pumps are treated with anti-corrosive coat. Stainless steel hellicoils are used for fasteners.
EASE OF MAINTENANCE :-
The impeller and diffuser can be inspected for wear/tear or replaced easily by removing the few bolts on the cover.
LUBRICATION :-
Oil in the motor chamber provides complete lubrication to the upper and lower motor bearing and the mechanical seal faces, the pump mechanical seal is lubricated by the oil in seal chamber, giving extra long working life and reducing down time.
ACCESSORIES FOR SUBMERSIBLE DRAIN PUMPS :- 
Semi open impeller available when specifically required.
Impeller and diffuser available in different materials, graded cast iron, stainless steel, Bronze, for both closed or semi-open Impellers.
Dry-running Protectors :-
Dry running protectors available for protection of pump set against running in dry condition, when the pit/sump water level has fallen below minimum submergence required
AGITATOR AND INJECTOR :-
To prevent sedimentation of the suspended solids on the bottom of the pit and to help the pump drain out even the thick and non-homogenous fluids, agitators and injectors are very useful.
CONTROL PANEL :-
Control panels consisting of extra thick fabricated box containing original instruments like voltmeter, Ammeter, indicating lamp, on-off switches, single phase preventor etc, all connected by heavy duty wiring.
P V C submersible 4core Cable (Oil and water proof)
Delivery Hose.
Motor Starter D O L /Star-Delta.
Gate valves etc.
