WQP2004.1THORDONWATER QUALITYPACKAGE

THORDON WATER QUALITY PACKAGEPrinciples of OperationA steady supply of relatively abrasive free water is animportant element in ensuring long, predictable, bearingwear life. With this factor in mind, Thordon has developeda self-contained supply, conditioning and monitoringpackage to ensure that an adequate supply of clean wateris consistently being delivered to both the forward seal andthe bearings.The Thordon Water Quality Package is designed to supplyseawater to the stern tube bearings for lubrication andcooling at a minimum flow rate of 0.15 litre/minute/mm (1US gallon/minute/inch) of shaft diameter and to removesuspended particles larger than 50 microns from the watersupply. A flow alarm is incorporated to alert the operatorto any low water flow condition to the bearings. TheThordon Water Quality Package is designed to operate on astand-alone basis, or can be fully integrated into the ship'scontrol and monitoring systems to allow operation in anunmanned machinery space.Thordon offers three Water Quality Packages in twoconfigurations designed to deliver flow to suit a wide rangeof shaft sizes, and provide an appropriate degree ofredundancy for the vessel involved.Technical InformationFrame Size (footprint): 1120 mm x 710 mm x 1220 mm(45" x 28" x 48”)Weight: 275 kg.
