Air-driven hydraulic power pack HBT

high-pressurebolt tensioner

Key Features:
• Standard and high-flow rate options — customisable output to match project throughput requirements
• Built-in FRL (Filter/Regulator/Lubricator) assembly for air quality management and consistent pump performance
• 7.5-litre hydraulic oil tank for sustained operation on high bolt-count and multi-tensioner jobs
• Intrinsically safe design — certified for use in explosive and hazardous classified environments
• Low-maintenance, long-service-life design for high-availability on critical bolting programmes
• Compatible with the full HYTORC tensioner range: topside, wind, subsea, and direct fit applications
• Compressed-air powered — ideal for applications where electrical supply is unavailable or restricted

Description:

Where compressed air is the available power source — offshore platforms, refineries, chemical plants, and hazardous classified areas where electrical equipment is restricted or prohibited — the HYTORC Pneumatic Tensioning Pump is the controlled bolting power unit of choice. Built for the rigours of heavy industrial maintenance, it delivers the reliable, precisely regulated hydraulic output that HYTORC tensioners require to achieve target bolt loads accurately and repeatably, every time.

The built-in FRL (Filter/Regulator/Lubricator) assembly is the engineering detail that defines the performance consistency of this pump. By continuously filtering contaminants from the incoming compressed air supply, regulating input pressure to the pneumatic motor, and lubricating internal moving components throughout operation, the FRL ensures pump performance remains stable across a full shift — regardless of variations in site air supply quality. The result is lower maintenance costs, longer pump service life, and hydraulic pressure readings you can rely on for accurate bolt load calculations.

Standard and high-flow rate configurations are available to match the throughput demands of the specific job. The 7.5-litre hydraulic oil tank provides the reservoir capacity needed for sustained operation on high bolt-count flanges or simultaneous multi-tensioner bolting setups, eliminating the interruptions that smaller-tank pump units introduce on complex joints. The intrinsically safe certification makes this pump one of the few tensioning power units fully approved for use in Zone 1 and Zone 2 hazardous areas — a critical advantage in petrochemical and offshore environments where an electric pump would be prohibited.

Whether powering a single HYTORC topside tensioner on a routine flange inspection or driving multiple simultaneous hydraulic bolt tensioners on a high-pressure pipeline connection, the HYTORC Pneumatic Tensioning Pump delivers the consistent, regulated hydraulic power your controlled bolting programme demands.
