Manual Hydraulic Hand Pump | HD20S-220 | HD30 | HD13AS-100 | DH40 | Ultra-High Pressure Hydraulic Pump

Industrial Manual Hydraulic Hand Pump Series

Product Overview: This series of Manual Hydraulic Hand Pumps is engineered for applications demanding a highly reliable, portable power source. Covering a broad range of specifications from standard to ultra-high pressure, featuring classic models like HD20/HD30 and integrated units with reservoirs like HD13AS/HD30AS. These pumps are widely utilized in field operations, laboratory pressure testing, mechanical maintenance, and as the power source for hydraulic tools (jacks, crimpers, etc.). The precision check valve structure and ergonomic handle design ensure smooth and easy operation even under extreme pressures.

Featured models include: HD20S-220, HD30, HD13AS-100, DH40, HD30AS-150, HE4AS-160, and accessories KR2-1, KS2-1, FR2-1, RD11, RC1E.

Key Technical Advantages:

• Dual-Speed/Two-Stage Displacement: Large flow output at low pressure for rapid filling, with an automatic switch to small flow at high pressure to minimize operator fatigue.

• Ultra-High Pressure Durability: Constructed with high-strength alloy steel or aerospace-grade aluminum, capable of delivering extreme pressures up to 100MPa – 220MPa (e.g., HD20S-220).

• Internal Safety Relief Valve: All pump bodies integrate a safety valve to prevent over-pressurization, ensuring system and personnel safety.

• Highly Integrated Units: The AS series (e.g., HD13AS-100) comes with built-in large-capacity reservoirs, offering a compact, ready-to-use solution.
