NON METALLIC

Rugged and reliable solution to handle liquids from a pit or a tank
This design eliminates the requirement for a bush bearing, associated hydraulic flushing / cushioning. Bearings are situated above the mounting plate and the shaft designed on a cantilever principle to ensure a deflection at the impeller end being less than 50 micron
These pumps have been designed for operating at elevated temperatures of upto 800oC with suitable material of construction for critical applications.

Cantilever Shaft Pump finds its application wherever high reliability, low maintenance are demanded. Cantilever Shaft Pump differs substantially from the regular Sump Pump.
To offer solutions to the difficult applications to the customers is indeed a professional challenge to us irrespective of the numbers involved. We have developed, manufactured and supplied pumps to customers including Department of Atomic Energy, Government of India.
A Cantilever Shaft Pump has bearings to support, and an overhung shaft that extends to the sump or tank. These bearings are mounted outside the liquid level so that they are never expressed to the pumping fluid.
As there are no submerged bearings, the pump can handle slurries, clear liquids and high temperature liquids without any need for flushing or sealing.
The pump can run dry without any bad effects or damage.
The Vertical Cantilever Shaft Pump requires no seals or packing when used in the open sump.
When used in the closed tank with hazardous liquids packing is used to prevent the fumes coming out.
The Vertical Cantilever Shaft Pump is designed to operate much below the critical speed as the sump depth increases the shaft diameter also increases. We guarantee the maximum deflection at the impeller side is less than 50 microns.
We prefer to operate the Vertical Cantilever Shaft Pump at 1440 RPM with the maximum depth of 1m. The tanks of higher depth can be emptied by having a tail pipe attached to the suction port.
These pumps can be used wherever automatic switching ON/OFF is required.
