General Information :

Working :

There are two Pumping Elements with Gear in Gear Principle. The Rotors are mounted on single shaft well supported on both the ends. As the Shaft Rotates, they mesh & un-mesh displacing the liquid axially through its pumping elements. Axially flow through elements ensures better suction capabilities, very low noise level and nearly pulsation free flow. These pumps have low power consumption compared to other brands due to unique mounting rotors.

Rotors are produced using sintered metal technology and the other components are produced using the advanced manufacturing techniques with all the necessary quality checks for repeated accuracies in dimensions, guaranteed interchangeability and near to perfect pumping characteristics.

This Series is highly reliable when put to work on field, has longer service life, practically needs no maintenance and has reduced cost of the end product than the conventional equivalent to the customer. A standard pump would consists of Rotors in Sintered Iron, with built – In Relief Valve, Shaft in EN-8 / SS-304, Lip Seal in Nitrile and all other parts in Cast Iron.

Application :

  • Unloading and Transfer of Lubricating Oil from Tanks and Barrels
  • Oil Circulation, Gearbox, Bearing and Pressure lubrication
