Custom Manufacturing Excellence since 1964
Hydraulic Hand Pumps assembled by Team PR can be either the primary or backup power system for actuators requiring hydraulic operations. These balanced ram design manual hydraulic pumps are assembled in two sizes providing 4 and 12 cubic inch displacement of fluid.
The pump incorporates the latest safety features available for use in air over oil hydraulic systems. Self-neutralization and anti-cavitation features are just a few of the engineered improvements offered in these designs. Every pump undergoes hydrostatic and functional testing prior to delivery. There are 75 components in each Hydraulic Hand Pump Assembly.
The robust Control Valve assembled by Team PR is the heart of control panels manufactured for use in thousands of natural gas and oil production and transportation applications and mining operations throughout the world.
Versatile by design, this double three way control valve, with integrated filtration, directs pneumatic or hydraulic pressure for precise manual or remote control of valve actuators. Each unit undergoes hydrostatic and functional testing in preparation for delivery on demand. The Control Valve Assembly contains 36 component pieces.

What's New at PR Machine Works
Two New Horizontal Machining Centers
PR Machine Works has purchased two new Horizontal Machining Centers. Our new Doosan NHP-4000 and Doosan NHP-8000 HMC's significantly increase the throughput volume in our CNC Milling Department, while increasing our milling size capacity to 55" x 47" x 54" xyz. These two new workhorse machines can handle the toughest materials while holding dimensional tolerances as close as ±.0002" and GD&T or true position of .003".
With 25 modern CNC machines, PR Machine Works can handle your most demanding requirements with superior quality and reliable, on-time deliveries. We are committed to providing our customers with the latest in precision machining technology, managed by some of the most talented manufacturing professionals in the business.
