Westfalia OSC 4
自清式离心分油机
Westfalia OSC 4 is a small self-cleaning separator for clarifying or purifying mineral oils (diesel and lube oil). The bowl with disc stack is driven through a centrifugal clutch and worm gear; a hydraulically controlled sliding piston opens the bowl for partial or total sludge ejection, and a centripetal pump discharges the clean oil. The manual and parts list covers specification and operating principles, safety, operation and cleaning, installation and motor connection, lubrication with mineral or synthetic oil, the maintenance schedule, gear and bowl assembly and disassembly, and the parts lists.
