Parker Hydraulic Unibody (HUB) actuator designed for fracking applications.
Parker Hannifin introduced its Hydraulic Unibody (HUB) Series Rotary Actuator with output torques of 1800 in-lb to 10,000 in-lb at its maximum operating pressure: 3000 psi (207 Bar). Built with an anodized housing and high-strength alloy steel pinion and racks, the HUB Series rotary actuator is designed for applications that are exposed to weather extremes: -40° to 180°F (-40° to 82°C) with nitrile seals. The rack-and-pinion gear provides efficiency characteristics (90-95 percent) and minimizes hydraulic power unit (HPU) size. The internally plumbed, lightweight design features two connection ports, a one-piece housing and allows for mounting directly on numerous process valves. In addition to injection equipment, the HUB Series actuator is suitable for a variety of other markets and applications where 90-degree rotation is desired in a compact actuator.
