TPI Double-acting Intelligent Tensioning Pump

The TPI double-acting intelligent tensioning pump introduces a pioneering dual-action hydraulic cycle that combines high-pressure extension with active hydraulic retraction, eliminating the reliance on gravity or spring force for tensioner reset. This is especially valuable in multi-tensioner series configurations where passive reset is slow or unreliable, such as wind turbine gearbox shrink disc installations and large flange assemblies. Compared to single-acting pumps, it can deliver up to 100% improvement in overall cycle efficiency.

Onboard high-precision pressure sensors and PLC intelligent control provide real-time monitoring and dynamic adjustment of output force and speed. The system supports preset pressure or tensile force targets, automatically stopping at the defined value to eliminate overloading and enable safe, unattended operation once parameters are configured. The HD digital display gives operators clear visibility of all key parameters at a glance.

Powered by a 3 kW servo motor driving a precision high-pressure pump, the unit delivers strong, consistent output even under demanding multi-tensioner loads. The ergonomic digital remote control and lightweight design reduce operator fatigue during extended operations. High-strength alloy construction with specialized heat-treated components and integrated multi-layer safety protection ensures reliable performance in harsh industrial environments.
