Ball Type Check Valves, (NRV) especially for Sewage

Features:

* Rubber covered sinking ball shutter
* Integral free passage
* Removable cover for easy inspection of the system
Function:
When the pump stops the sinking ball moves down to shut off the passage into the valve body & prevents the column of water in the section of pipe above the ball returning to the source. When the electric pump is restarted the liquid pushes the ball upwards and due to the shape of the valve body, it is guided to one side, completely freeing the passage. At each restart the section of pipe above the valve is already full, preventing waterhammering.
Advantages:
These are preferred over Spring Type Check Valves. Sewage generally tends to get stuck on the springs & thereby, increasing the load on the pumps. This can also create a situation in twin pump systems where the pump keeps returning a certain amount of sewage to the sump due to non closing of Spring Type Check Valves.

Coupling Foot Base

Features:
* Mobile seal part on fixed in cast iron against rubber
* Mobile part self-positioning on fixed part
* Fitted with upper guide tube for perfect parallelism of the lowering & raising guides.

Advantages:
Lifting of pump is facilitated. This easiness in lifting the pump periodically ensures that the coagulants fall off due to lifting. This enhances the pumps life immensely & reduces chances of failure.


Function:
The bottom coupling device is specifically for horizontal delivery types.
Once it is fixed on the bottom of the tank it allows the pump to be raised or lowered without emptying the tank. The mobile section, an integral part of the pump, descends through the pipe guides anchored to the fixed part of the device and to the top of the tank by means of the pipe guides, until it self-positions in the correct operating mode.
