HUB Rotary Actuator

The Hydraulic Unibody (HUB) series rotary actuator is suitable for applications exposed to weather extremes. The rack-and-pinion gear design provides greater durability and life than comparable splined gear designs, provides efficiency characteristics (90-95%), and minimizes hydraulic power unit (HPU) size. The internally plumbed, lightweight design has two connection ports, which reduces time required for installation for both injection equipment OEMs and well service companies. Its one-piece housing eliminates leak paths and external connections, which means fewer plumbing hoses and fittings are required.
