HaldexF25 gear pumps are designed for low noise, high efficiency bi-rotational operation. The 14-tooth gear provides lower pressure ripple which results in lower noise. The cast iron construction also contributes to noise reduction. In addition, cast iron housings allow gear tips to generate their own run in paths, creating higher volumetric efficiency. The drive gear and drive shaft as well as the driven gear and shaft are one piece construction. This eliminates the potential problems of fretting and stress fatigue associated with two piece construction.
