Getting the most out of your machinery often depends on close integration between all components, with the correct specification of couplings between them to ensure proper shaft alignment, optimise performance and minimise wear. The experts at jbj Techniques guide us through the design considerations for coupling hydraulic pumps to prime movers. Shaft Oil Seal
Hydraulic adapters can also be manufactured to couple pumps to electric motors in hazardous area applications, meeting ATEX standards. Couplings supplied for these applications provide an anti-static and flameproof drive which meet zone 1 area requirements, conforming to all of the above standards. Also available are spider and gear couplings which are certified to zone 2 standards. An area of coupling specification in hazardous area applications that needs to be considered is possible high temperatures generated by a piston pump shaft seal when the pump is cycling between different pressures. This process will often take the seal temperature beyond the levels required by the relevant ATEX standards. To address this issue jbj Techniques offers the wet mount series of bellhousings. This specially designed assembly allows a pumped cooling flow to be passed over the seal face and through an auxiliary cooler. This in turn reduces the seal face temperature which can be maintained at an acceptable level.
