PRECISION PRESSURE REGULATION FOR FLANGE JOINT INTEGRITY.
Boltorq hydraulic bolt tensioner power packs are engineered to safely generate extreme pressures up to 4000 bar required to elongate heavy alloy steel studs without pulsation drift:
Dual-Stage Reciprocating Pumping & Rugged Steel Protective Frame
Rapidly pre-fills tensioner load cells during low-pressure advance, then automatically ramps to ultra-high pressure up to 4000 bar. Designed with compact, lightweight roll cages and top handles for easy maneuverability across plant scaffolding and shipyards.
Calibrated High-Precision Pressure Gauges
Features clear, high-accuracy dial readings in both Bar and PSI (10,150 to 58,000 PSI) for verified stud elongation calculations.
Spark-Free Air Drive Safety
BTPHP and SHNP air-driven pumps operate without electric arcs or sparks, making them fully compliant with hazardous site safety protocols.
High-Performance Quick-Connect Couplings
Equipped with leak-free quick couplers for fast, safe connection to tensioners and manifolds.
CRITICAL HIGH-PRESSURE POWER SOURCE FOR HEAVY INDUSTRY.
Boltorq bolt tensioner pumps provide the high-pressure fluid power necessary to drive multi-stud tensioning assemblies across high-risk industrial environments. By enabling uniform pre-loading across critical bolted joints, our pumps minimize shutdown durations, prevent dangerous flange leaks, and maintain operational compliance under extreme working temperatures and pressures.
Wind Power Infrastructure
Supplying 1500+bar continuous hydraulic pressure for turbine tower flange tensioning and rotor blade joint assembly.
Shipping Vessels & Marine Engineering
Delivering lightweight, portable hydraulic power for main engine cylinder head bolts and marine propulsion couplings.
Petrochemical & Oil Refineries
Driving spark-free air tensioner pumps on main reactor heads, hydrocracker pressure vessels, and high-pressure pipe flanges.
FREQUENTLY ASKED QUESTIONS ABOUT
BOLT TENSIONER PUMPS
What is the maximum pressure output of Boltorq bolt tensioner pumps?
Boltorq BTPHP air-driven pumps deliver up to 4000 bar (58,000 PSI), SHNP pneumatic pumps reach up to 3320 bar, and HSNP electric power packs deliver up to 3000 bar (43,500 PSI).
Can a single tensioner pump operate multiple bolt tensioners at once?
Yes. BTPHP and SHNP series pumps are compressed air driven, operating without electrical arcs or sparks, making them ideal for explosion-proof site requirements.
What power supply is required for the HSNP electric tensioner pump?
The HSNP series runs on a standard single-phase 220V / 50Hz electrical connection and features a 1.1 KW high-performance motor.
