Double Helical Herringbone Gears provide quiet, pulse-free flow with better load carrying ability, greater strength and minimum hydraulic shock.

Timing Gears drive and transmit power, eliminating metallic contact of the pumping rotors and promoting long pump life.

Between Bearing Design virtually eliminates shaft deflection, even while accommodating heavy, highly viscous loads.

Heavy-Duty, Double Row Roller Bearings capable of carrying high radial loads, a short bearing span, and a husky shaft minimize rotor deflection.
