line of maintenance-reducing stuffing boxes is now available from The Johnson Rubber Company's Duramax Marine Division. In addition to making packing changes easier, several of the company's, heavy duty stuffing boxes are specifically designed to cut the need for drydocking.
Three of the popular types of stuffing boxes feature the exclusive Duramax inflatable "Air Seal" rubber ring which, when inflated, seals itself around the shaft sealing out water when a packing change is required. Packing can be changed even while in the water, eliminating the need for drydocking. When the repacking is complete, the inflated seal is deflated. At this point, the rubber ring automatically retracts clear of the shaft.
The company offers a broad line of stuffing boxes for many marine applications. For service at forward stern tube locations, stuffing boxes with shaft sizes ranging from 2% inches to 15 inches provide water/ grease lubrication, grease lubrication or water lubrication. Made of cast naval bronze, Duramax stuffing boxes are engineered for extra strength at critical stress points and are precision machined with female recess for mating with Duramax water lubricated flanged type bearings.
Stuffing boxes with machined male pilot for use with the Duramax water-lubricated demountable rubber stave bearings are also available.
Split type stuffing boxes, as well as boxes of cast aluminum or mild steel are also available in certain models and sizes.
Bulkhead or rudder stuffing boxes ranging in shaft sizes 2% to 7% inches are offered in bronze and can be supplied with integral steel flanges for bulkhead welding. Also offered in the line are a series of bronze stuffing boxes and stern castings for shaft sizes ranging from 1 inch to 6 inches, featuring rugged construction with thick mounting flange and thick ribs for better shaft support.
