Plant / Mill Works

In the early 1990’s Open Loop Energy researched, developed and tested enhanced performance modifications in the “Tramp Release” cylinders. These modifications increased the service life of the cylinders by 4-5x which significantly reduced operating costs for our mining partner.

Innovations: Extending Chain Life

A mining partner asked Open Loop Energy to extend the chain life of their copper production line. The company improved the OEM design and more than doubled the customers chain life. Prior to this innovation individual chain links could not be repaired thus required entire sections of chain to be replaced. Now the customer can replace individual links with repairable pieces.

Custom Power Units

Pictured here is one of the custom designed and built power units by our company. Power units can be electrical driven or driven by a diesel or gas power. Customers specify what duty a power unit is required for and Open Loop Energy Fluid Power Specialist and CAD systems design the perfect configuration.

Vertical Turbine Pump Rebuild

At the Safford shop location Open Loop Energy can rebuild stainless steel vertical turbine pumps. Due to proprietary repair processes and CNC machining capabilities, customers realize lower operating costs and longer pump life by rebuilding vs. replacing bowls with new parts.

Tramp Cylinder Rebuilds

Open Loop Energy has designed improved sealing properties to repair badly damaged tramp cylinders. Using the Company’s “Seal Specific” technology, damage to the rods can be completely avoided. Proprietary design changes have given customers superior life over OEM designs. In addition, customers accumulators associated with tramp cylinder systems can be rebuilt using Parker-Olaer quality bladders and rebuild kits. Units are charged and tested for quality and function before shipment back to customers.
