Applications • Compressors • Mixers, agitators and reactors • Pumps • Fans and blowers Applications • Turbo generators • Service pumps • High speed wind turbine shafts • Boiler feed pumps • Cooling towers • FGD pumps • Nuclear handling equipment Power Generation John Crane couplings are able to satisfy the demands of power generation...

Industries served Pulp and Paper A wide variety of couplings that are designed to accommodate such specific pulp and paper industry requirements as zero backlash for paper-making machine use and rugged reliability for pulp mill rotating equipment applications. This range also features a series of new models which have been specifically created to provide improved performance in applications where gear couplings have traditionally been used. Typical applications include: • Roll drives • Process pumps • Pulpers • Dryers • Vacuum pumps • Calendars • Refiners • Winders Marine John Crane has an...

Engineered Coupling Solutions 07 General Industries John Crane’s range of power transmission couplings provide a versatile and flexible solution for virtually any rotating equipment application where reliability and maintenance-free operation are necessary. Water and Waste Water The need for maintenance-free operation from unmanned pumps in remote locations is one of the key reasons why Metastream couplings are well suited to water and waste water industry use. Their versatility enables them to satisfy many different types of application and their rugged construction allows them to resist...

Product Range Metastream Flexible Couplings Metastream flexible power transmission couplings are designed for applications where the shaft ends are nominally ‘in line’. They have earned an enviable reputation for their ability to accommodate misalignments while still minimising vibration and imposed loads on the coupled machinery. High-speed applications are well served by the couplings’ high torsional rigidity and natural balance features. Each Metastream coupling incorporates spacer retention anti-fly features, plus an all-metal construction that eliminates the need for lubrication and...

Engineered Coupling Solutions 09 M Series M Series couplings can handle a high degree of misalignment and still provide outstanding levels of reliability which is why many users now specify them by name. They feature a unique design that transmits power across a spoke-form membrane pack. This membrane pack, together with the M Series unique anti-fly bearing, ensures that in the unlikely event of membrane failure, the coupling will disconnect the drive from the driven machine and prevent damage occurring. Key Benefits • Unrivalled reliability - 50 years MTBC (mean time between change) • API...

L Series Couplings in the L Series are designed for a wide variety of industrial application which demand all the benefits of a membrane coupling from a simplified and cost-effective package. The L series units deliver a maximum value solution, but one which does not compromise on reliability or safety and they feature robust membrane units that have been designed to provide reliable operation in the most demanding applications. Product Range Key Benefits • Built in overload protection • Pre assembled membrane pack for ease of overall assembly • Low imposed loads on bearings T Series –...

11 Other products in the range • C Series rigid couplings for vertical pumps (API 610) • A Series urethane wrap-around coupling for demanding industrial applications Technology John Crane employs advanced computer-aided design and finite element modelling techniques in its quest to continually develop and improve its range of couplings and combines these with a comprehensive range of test and evaluation facilities. The company continues to extend technological and material boundaries in its efforts to provide bespoke solutions which satisfy the most demanding of applications. Engineered...
