Osaka Jack Mfg. TWAU-1.8 Ultra-High Pressure Hand Pump

Osaka Jack / OJ Hand Pump

Specifications

• Model: TWAU-1.8 (OSJ-TWAU-1-8)

• Effective oil volume: 1.8 L

• Pressure rating: Low pressure 3 MPa / High pressure 300 MPa

• Displacement per stroke: Low pressure 11 mL / High pressure 3 mL

• Connection: M22×1.5 (high pressure)

• Weight: approx. 13 kg

• Material: Pressure-resistant parts made of special steel for high durability

Operating Features

• Two-stage switching: Fast advance at low pressure, accurate pressure buildup at high pressure for improved efficiency.

• For single-acting cylinders: Works with spring return or self-return cylinders; manual retraction with intuitive operation.

• Ultra-high pressure capability: 300 MPa class pressure resistance, suitable for ultra-high pressure lifting, press fitting, straightening and similar applications.

Usage Recommendations

• Recommended oil: ISO VG 10 machine oil or equivalent.

• Recommended installation: Vertical mounting only; avoid horizontal or inverted use.

Typical Applications

• Ultra-high pressure lifting and straightening of large molds and tooling

• Precision leveling of bridges, construction and marine structures

• Press fitting / disassembly of heavy components in metallurgy and steel equipment

• Ultra-high pressure hydraulic testing for aerospace, rail transit and other equipment

Selection & Matching Notes

• Best matched with single-acting cylinders / jacks of spring return or self-return type.

• High-pressure hoses and fittings must be rated for 300 MPa; seamless steel tubes or high-strength hydraulic hoses are recommended.

• Drain oil and apply rust protection before long-term storage; replace with new oil before reuse to ensure cleanliness.
