Product Reviews

Series Features:

Capacity Range: up to 550 m3/hr
Viscosity Range: up to 207600 cSt
Temperature Range: up to 80° C
Pressure Range: up to 16 Bar

Operational Features:

Our precisely manufactured screws by advance CNC machines ensures highly efficient performance.
Provision of timing gear pair maintains the small positive clearance between the screws and thus prevents the metal to metal contact assures negligible wear, tear and long service life of pump.
Our twin-screw pump can be run dry for some time without any damage, and suitable for handling the fluid with low lubricity and low to high viscosity range.
Due to the less internal velocities of pair of screw, the suction power is practically the lowest even while handling highly viscous product at motor speed.
The fluid in this pump travels axially without turbulence, rotation or churning and the noise and vibration created are almost the lowest.

Safety Measures:

Following points should be kept in mind as a safety measures while installing and running the pump:

Read the instruction manual thoroughly.
Do not run pump dry.
All the guards and shields should be at their proper places before running.
Make sure that the pump runs in assigned direction only.
Check all the lubricants before installing.
Pump casing should be filled with liquid.
Do not use liquid other than that for which the pump is designed.
Use proper strainers and filters to protect pump from abrasives.
