HSP High-Strength Dual-Stage Manual Hydraulic Pump

The HSP high-strength dual-stage manual hydraulic pump delivers reliable high-pressure output through operator-powered pumping, offering a portable and energy-independent hydraulic power solution for field maintenance, construction sites, and emergency applications. Built from high-quality alloy steel, the pump body and working components provide high structural strength and pressure resistance, ensuring long service life under the repeated mechanical loading inherent in manual pump operation.

The dual-stage pressure design allows the pump to automatically switch between high-flow output for rapid cylinder advancement and high-pressure output for precise load application, reducing operator effort across the full stroke cycle. Output pressure is adjustable to match the requirements of different connected tools and applications, giving users control over the hydraulic force delivered without requiring additional equipment. This adjustability also allows the pump to serve a broad range of tool types from low-pressure to full-rated pressure applications.

An internal safety valve provides reliable overload protection, preventing pump body damage and connected tool failure caused by excess pressure. The HSP shares core functional characteristics with the HAP model while offering a complementary form factor and configuration, giving users the option to select the variant best suited to their specific tool combination and operational environment. Compatible with jacks, tensioners, small cylinders, cutters, punches, and other manually-supplied hydraulic tools across maintenance, industrial, and civil engineering applications.
