Manual Hydraulic Pump
Manual hydraulic pump for actuators enables emergency hydraulic operation without air
Product overview
This manual hydraulic pump is an emergency operating accessory for high-torque hydraulic and pneumatic actuators. It uses manually generated hydraulic power to open and close valves when compressed air is unavailable, electrical power is lost or the air supply fails. The pump is lightweight and easy to operate, with an integral sealed hydraulic cylinder that prevents leakage. Its pressure-release and return mechanism quickly unloads pressure and resets after operation.
Standard hydraulic connections connect directly to hydraulic actuators for large butterfly valves and high-torque ball valves. The housing resists rust and corrosion, and the oil reservoir has sufficient capacity for multiple opening and closing operations after a single fill. No external power is needed, and one person can operate the valve manually. It provides a second emergency operating safeguard for critical pipelines and increases operational safety redundancy.
