A new fuel/water separator means that you can virtually eliminate free water in fuel.
Caterpillar’s new Cat Advanced Efficiency fuel/water separators (FWS’s) replaced the usual detachable water collection bowl with a drain valve for easy servicing. The one-piece stepped metal canister design isolates the collected water from the filter element. You can now remove more than 98% of debris 10 microns and larger 87% of dissolved water from fuel.
Water contamination can present a major threat to mechanical health. Water ingress can compromise film strength, resulting in scuffing and eventual seizure. According to Barloworld Equipment group product specialist Reuben Phasha, un-dissolved water quantities greater than 0.1% can cause major damage.
