Literature describing the company's automatic Circoolmatic oil circulation and cooling system for stern tube seal lubrication has been published by Waukesha Bearings Corporation, Waukesha, Wis. The system is recommended for 710 mm seal systems and larger.
Circoolmatic pumps oil from the forward seal through a sea-or-freshwater cooling system, providing maximum lubrication. Oil may also be used as a coolant and may be pumped from the mainstern tube bearing sump into the cooling coil, then into the main head tank.
The Circoolmatic is a flooded circulating type system, with the seals, reservoir, and circulating pump fitted and primed at all times to maintain seal oil at a satisfactory cooling level. Standard features included are a fail-safe alarm system; pilot lights indicating proper pump operation and adequate oil level; and an audible alarm that signals low oil level.
