Plymouth, MN — New CD Couplings® from Zero-Max are an ideal choice for use with fixed displacement hydraulic pumps driven by servo motors. CD Couplings provide the ideal combination of high dynamic load capacity and high torsional stiffness to ensure reliable system operation.
“This new pump drive technology has become increasingly popular because of dramatic improvements in their energy efficiency and noise reduction”, reports Robert Mainz, Zero-Max sales manager. “These pump systems utilize the power and precision that only a servo motor can provide. The system pressure is controlled by modulating the output volume of a fixed displacement pump. This is made possible utilizing a high performance control system and the high performance qualities of a CD shaft coupling.”
CD couplings have unique design qualities that are robust to ensure that these hydraulic pump applications are reliable and productive. CD Couplings are designed so that the working part is made of a composite material. The composite disc design withstands the punishment and stress of a servo motor, “everything a variable speed pump drive system can dish out,” report OEM designers. They also report that CD couplings enable these systems to not only perform well in test lab environments, but more importantly, on the production floor.
