Rigid adjustable couplings from Lovejoy

A new series of rigid adjustable type couplings, designed for easy axial adjustment of impeller clearance in vertical pump installations, is being introduced by Lovejoy Inc. (Illinois, USA). As an addition to the Lovejoy/Sier-Bath Gear Coupling Line, the new RA/RAHS Series offers both close-coupled and spacer styles in standard (RA) type and high-speed (RAHS) type, which is specially balanced to API 610 8th edition tolerances. Spacer styles provide a centre section that can be removed to let the impeller lift out for maintenance without disturbing and having to re-set its vertical clearance adjustment, or demounting either the motor or pump housing. All styles and types are available in either AISI 1045 steel or stainless steel, for broad application across water, wastewater, power generation, refinery and many other industries.
