A 30 Year Milestone Celebration!
As the Leistritz family looks forward with anticipation, we also look back with admiration. Today we look back upon the tenure of Jack Oriente, Leistritz Shop Manager for 30 years. Jack is a self-taught machinist, whose fascination for fabrication began back in 1979 when he began rebuilding a ‘56 Chevy Belair. In 1983 he won an award for outstanding detail on that rebuild. Thirty-seven years later and Jack continues to display that same level of detail with every one of the nearly one-thousand pumps he has worked on in the last 30 years.

Optimizing Lube Oil Pumps for Rotating Machinery
A three-screw pump can provide smooth, pulsation-free flow.

The circulating lubrication oil system is essential for cooling and lubricating all kinds of rotating machinery. In typical train steams or gas turbines, diesel engines, reduction or step-up gears, compressors, generators, pumps or expanders could be included. The oil system includes a number of components for which the pumps provide adequate flow and pressure—such as the gears, journal and thrust bearings in the machinery. The cooling and filtering of the oil are equally dependent on pump flow and pressure to function properly.

The costs associated with replacing and upgrading older pumps in vintage power plants and process facilities have often been an obstacle for life extension programs or service change projects such as going for low sulfur fuel oils. However, when regulatory and operational demands make new construction hard to economically justify, it may be the only way to go.
