New couplings for pump uses
Torsiflex-i couplings, designed for process pump applications, are now available with Torsi-Lock hubs
Developed for API 610 service, couplings feature a disk pack design, allowing for greater torque load in a smaller size, which results in lower weight, the firm notes. Max bores matched to NEMA motor shafts provide up to a 60% weight savings, the firm points out. A plug-in spacer design allows installation and removal without disturbing the hubs. All models are ATEX compliant and come standard with a zinc phosphate coating, a built-in antiflail feature, and inch series hub attachment screws (metric available).
Torsi-Lock offers the ease of a slip fit with the power of a shrink fit. This cold-install hub provides the secure torque transmission and balance repeatability of an interference fit. The company combined its Ameriloc shaft locking devices with Torsiflex-i to provide a fully preengineered solution that meets the balance requirements of API 610.
Cold installation of Torsiflex-i couplings with Torsi-Lock hubs means no hot work permits, providing added safety and productivity in hazardous environments.
Torsi-Lock hubs provide easy, repeatable removal and installation, and eliminate fretting of hub to shaft. The hubs compensate for variances in shaft spacing—units can be slipped on and fixed in the needed location. The hub and locking device are balanced and match-marked to help assure optimum balance performance.

New oil field engines meet US EPA Tier 4 Final standards
New Cat C27 ACERT and C32 ACERT oil field engines meet US EPA Tier 4 Final emissions standards 4 years ahead of regulatory mandate. The 800 bhp and 1,125 bhp units feature technological improvements in key systems to achieve Tier 4 Final status, including a new high-pressure fuel system with refined injection control, next-generation turbochargers, refined air system management for NOx reduction, an enhanced suite of maintenance-free aftertreatment technologies, and advanced electronics and control software.
