Bar Stool Hydraulic Lifting Pump

The hydraulic lift pump is the core component of hydraulic lift chairs, enabling smooth lifting, lowering, and rotation functions through fluid pressure transmission. Its working principle is based on changes in liquid pressure within a sealed system, where the hydraulic rod and gas spring work in coordination to achieve precise adjustments. ‌

The hydraulic lift pump utilizes a piston structure filled with high-pressure nitrogen, leveraging gas pressure differences to drive the movement of the lift shaft. When the adjustment lever is pressed, changes in gas pressure drive the piston to move, thereby lifting or lowering the seat. This design ensures uniform and smooth adjustment speed, preventing sudden drops or jams.

The hydraulic lift pump not only enhances technicians' work efficiency but also provides customers with a more comfortable and safe experience. It is widely used in barber chairs, beauty chairs, bar stools, executive chairs, office chairs, and more.
