KIRLOSKAR 'NW / NW 'D'  Series ENGINE / MOTOR COUPLED PUMPS :

 

 

 

Features :

 

*  Suction lift upto 7.5Mtrs.

 

*  Top flat efficiency curve minimum variation in efficiency in entire operating range.

 

* Efficiency at par with Internationally available pumps higher upto 10 points than minimum required by Indian standard specifications.

 

*  Can be run direct/through pulley with Engine / Motor.

 

*  Design to prevent overloading of Engine / Motor.

 

*  Designed for automatic air release during priming,

 

*  Dynamically balanced rotating parts ensure minimum vibrations.

 

*  Replacable wearing parts a nd hence longer life.

 

*  Better sealing against air leakage due to greater stuffing box depth.

 

*  Provided with outer bearing stand (against requirement) for better support to pulley.

 

 

 

Application :

 

*  Irrigation.

 

*  Industries, for clear water handling.
