HPM-UHP Series 1000-4000 Bar UHP Hand Pumps
Engineering Overview & Structural Features
The HPM-UHP Series Two-Speed Ultra-High Pressure Manual Hand Pumps deliver extreme hydraulic pressures from 1,000 Bar (14,500 PSI) up to 4,000 Bar (58,000 PSI) for critical mechanical oiling disassembly, hydraulic expansion sleeves, and high-load hydraulic bolt tensioners. Built from high-strength alloy steel with an integrated high-precision automatic two-speed switching valve, the HPM-UHP Series delivers voluminous 32.0 cm³/stroke low-pressure priming (18 Bar) for swift tool take-up, smoothly shifting into precision high-pressure displacement (0.6 to 2.1 cm³/stroke). Featuring calibrated internal overload relief protection, high-pressure gauge blocks, and standard BSP 1/4" ports, it combines robust site portability with smooth handle effort.
1,000 - 4,000 BAR EXTREME PRESSURE RANGE
Engineered across 6 graduated pressure ratings (1,000 Bar, 1,500 Bar, 2,100 Bar, 2,800 Bar, 3,500 Bar, and 4,000 Bar) to power hydraulic shaft expansion sleeves, bearing removal tools, and bolt tensioners.
TWO-SPEED AUTOMATIC INTERNAL SHIFT VALVE
Delivers voluminous 32.0 cm³ low-pressure displacement at 18 Bar for rapid tool stroke extension, automatically transitioning into smooth 0.6 to 2.1 cm³ high-pressure metering with modest handle effort (20-39 kg).
INTERNAL OVERLOAD SAFETY RELIEF VALVE
Factory-calibrated tamper-proof internal pressure relief bypass prevents accidental over-pressurization, providing positive structural protection for ultra-high pressure tensioning tools, hoses, and operators.
HIGH-STRENGTH ALLOY STEEL & 10.8 KG MOBILITY
Monobloc forged alloy pump head and steel reservoir resist cyclic fatigue pulses up to 4,000 Bar. Weighing just 10.8 kg, the compact chassis enables agile mobilization across wind turbine nacelles and plants.
INTEGRATED GAUGE ADAPTOR & BSP 1/4" PORT
Standard BSP 1/4" oil outlet port pre-fitted with a heavy-duty stainless pressure gauge adaptor assembly, facilitating real-time monitoring and direct connection to 1000-4000 Bar micro-bore hoses.
1,600 CM³ & 2,200 CM³ ALLOY RESERVOIRS
Standard 1,600 cm³ and extended 2,200 cm³ usable oil reservoirs supply ample hydraulic volume to energize multi-tensioner rings and heavy shaft sleeve injection systems without intermediate refilling.
OEM Cross-Reference & Dimensional Interchangeability
Two-speed ultra-high pressure manual hydraulic hand pumps rated for 1,000 to 4,000 Bar (14,500 to 58,000 PSI), engineered for bolt tensioning, shaft oil-injection disassembly, and hydraulic expansion sleeves across 1.6 to 2.2 L reservoirs. 1000 - 4000 Bar UHP Manual.
