Optimizing Lube Oil Pumps for Rotating Machinery

A three-screw pump can provide smooth, pulsation-free flow. by Sven Olson 03/25/2020 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. (more…)

Revitalize and Upgrade Power Plants with Re-Engineered Pumps

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. (more…)

Multiphase Technologies Increase Production Rates

The American Oil & Gas Reporter February 2020 In today’s oil field economy, it makes a lot of sense for operators to be well informed about improvements and enhancements to conventional artificial lift methods to optimize and extend production from producing reservoirs. (more…)

Pumps in Transfer and Pipeline Service

Twin-screw Pumps

Twin-screw or three-screw pumps are often used in crude oil pipeline services. Three-screw pumps can boost pressure from laterals to the main trunk lines, while twin-screw pumps are predominantly used in the main line boosting stations. (more…)

Multiphase Pump and The Benefits to Oil and Gas Production

Multiphase pumps are finding added use as a supplement to conventional artificial lift systems to reduce the production footprint and environmental disturbance by combining oil and gas transport in a single multiphase pipeline to a central process facility. In tight shale production, the typical rapid decline of the natural reservoir pressure and added associated gas production demands solutions justifying increasing drilling, fracking, and completion costs.

Leistritz Has a Lock on Precision Products

Manufacturing Best Practices January 23, 2020 Leistritz Advanced Technologies Corp. recently delivered a machine to a customer so it could produce lead screws for a large aerospace manufacturer. Attila B. Catto, president of the Leistritz Machine Tools division, explains the customer chose the Leistritz machine because it needed to use a space-age material, and no other manufacturer could provide the same tool life and production capability as Leistritz’s machine.

Pumps in Upstream and Midstream Oil and Gas Production

In connection with upstream and midstream oil and gas production, pumps perform a large variety of services enabling gathering and processing of hydrocarbons and their derivates for the benefit of industrial users and consumers. These pumps are traditionally divided into two categories or principles: hydrodynamic and positive displacement pumps. (more…)
