Self venting casting prevents air lock with low radical force.
B. IMPELLER
Closed, Semi Open, Open, Non clog, Vortex & Closed type staggered multi vane impellers to cover all application industry.
Back vane relives pressure on Stuffing box & reduces leakages.
Balancing holes are provided to reduce axial trust.
