Mico, Incorporated recently announced a collaboration with Haldex Hydraulics Corporation to offer an integrated accumulator charge valve and gear pump package. The integrated package reduces the amount of plumbing and mounting hardware needed, resulting in a less complex, more durable and efficient design. This product is designed for vehicles that use a full power hydraulic brake system and requires power-off braking by storing energy in accumulators.
Contributing to the package's long-lasting design is the Haldex gear pump that is known for its reliability and durability. The gear pump's simple design also makes it a more cost-effective solution than alternative pump designs. The package greatly reduces the potential for leak paths by decreasing plumbing, which also makes the system easier and less time-intensive to incorporate into an overall design. Additional efficiency comes from the package's design feature that provides excess flow from the charge valve to operate steering, cooling or implement functions.
The integrated accumulator charge valve and gear pump package comes with the option of single or dual accumulator ports with four charging rate options between 0.5 gallons per minute (gpm) and five gpm. The unit displaces up to 1.4 cubic inches with system pressures up to 3,000 psi maximum continuous.
