Sewage Pumps

These pumps are most suitable for :-

• Drainage and irrigation installations
• Sewage disposal for housing colonies basement, toilet blocks etc.
• Marine installations

The basic advantages of these pumps are :-

• Economy in floor space
• Prime mover can be mounted at an elevation as shown or at a higher elevation. Higher elevation of prime mover is possible by adding extra adaptors, transmission shaftings and intermediate bearings. This reduces the risk of submerging the electric motor in case of accidental flooding of the dry pit.
• Ease of maintenance. To dismantle, the mounting cover is to be unbolted from the casing after motor has been removed. The rotor assembly is drawn out upwards complete with stuffing box, bearing housing etc. This rotor assembly can then be completely dismantled at a convenient location. Due to the back pull out design, choking of the impeller can also be similarly, removed easily.

 

 

Self priming sewage pump is a highly precise and yet a very rugged unit.
The operation of the pump is as follows:
A. vacuum pump starts.
B. Water level in float chamber rises. Float rises and operates the level switch.
C. Vacuum pump shuts down and main pump starts. Whilst main pump is in operation and pump looses prime then the priming pump restarts to automatically maintain the prime. As soon as priming is completed, the vacuum pump shuts down and main pump goes on operating. 
In case the level of product in the suction tank goes below the level of the suction line and pump looses its prime, the vacuum pump cuts in. The main pump continues to function for a predetermined time limit-approximately 2.5 minutes. After the predetermined time limit is over, the electric control panel shuts down the main pump motor. 
The whole system is absolutely automatic and has been developed after long research, to give outstanding performance under arduous service conditions.
