Flexible couplings for diesel pump drives

This new coupling follows the recent launch of the single piece, torsionally-stiff Centaflex-KF. This is a stronger yet thinner lightweight flexible coupling offering construction plant operators more flexibility and superior stiffness. Designed for use in plant, crushers and other construction equipment, the new Centaflex-KF allows increased levels of radial compliance and has a short-term resilience to high temperatures of up to 120°C, owing to an evolution in rubber blending compounds. This is of particular benefit if the need to operate in sealed enclosures is a consideration.

Centaflex-KF consists of a lasered metal adapter plate for the flywheel connection, with a secondary flange made of moulded reinforced plastic, bonded to an extremely strong layer of vulcanised, temperature resistant rubber. The adapter plate is considerably thinner than that of the Centaflex-KE and rather than rollers around the circumference, it is the strong rubber central core, vulcanised to the mounting plate, that gives the CF-KF its superior stiffness. This improved stiffness means that the torsional activities and resonances are moved further from running speeds.

Centa also produces a range of complementary products for use with hydraulic pump drives, including the latest version of the Centa Belt Box, Centa’s Hydraulic Pump Mounting Kits, including the two-piece pump mounting plate, and other hydraulic drive related flexible couplings. These are all designed to suit any diesel engine-driven industrial application where the elimination of misalignment, vibration, noise, or even, weight reduction, is required.
