Auxiliary Hydraulic Pump

An auxiliary hydraulic pump is a secondary pump fitted to supply hydraulic power to systems such as sweep gear, brushes, or suction equipment. Depending on design, it can support more stable flow as engine speed varies during operation.

Consistent hydraulic delivery improves controllability and supports predictable engagement of hydraulically actuated components.

Auxiliary supply is relevant for road sweepers with operator, and hydraulic system checks often sit alongside inspection of a universal joint coupling on vehicles with driveline-driven auxiliaries.
