DEKKER recommends that this oil be used to obtain the ultimate performance from the HullVacproduct and to maintain the 3-year warranty period.Oil should be changed whenever it appears white or yellow, foams consistently, or when dirty. Oil changefrequency depends on the materials being pumped. For clean operation, oil should be changed every 3000operating hours or every 9 months, whichever comes first. For other operation, oil change could rangefrom once or twice a week or less dependent upon the type of application.The most common contamination is water in the oil and can be recognized by a milky appearance visible inthe site port. Closing the pump inlet valve and operating the gas ballast valves for 2 to 4 hours can removethis water. If this does not clear the oil, change it. In applications with consistent water accumulation,draining the water from the reservoir prior to operation is recommended.HullVac OilContainer Size Standard Water Application1 Gallon Container 5120-0010-002 5120-0010-0035 Gallon Container 5120-0050-000 5120-0050-00855 Gallon Drum 5120-0550-000 5120-0550-002Safety Data Sheets (SDS) available upon request.
