Apiezon AP201 is the leading brand of vapor booster fluid and should not be confused with lower quality '201' imitations. AP201 is superior to other hydraulic fluids because it provides low pump downtime, long service life, ease of maintenance and reduced top fill. The AP201 is widely recognized as the most reliable and cost-effective product on the market.
To achieve the shorter pump downtimes demanded by industrial systems, booster pumps need to achieve high pumping speeds. The AP201 is custom manufactured to achieve these speeds. It also has a high critical backing pressure allowing the pump to switch over faster thus reducing pump downtime.
The Apiezon AP201 also has features specifically matched to the vapor booster pump, allowing it to achieve excellent boiler temperatures and maximize heater life.
Unlike other lower quality oils, AP201 is specially formulated to be highly resistant to oxidation. This prevents viscosity build-up and tarry deposits that build up on booster pump vanes and nozzles. Oil life is thus extended and the time required to drain and clean the system during servicing is reduced.
A strong evidence of its good quality is that the manufacturer of the steam booster pump specifies Apiezon AP201. If other oils are used, the manufacturer's warranty will be invalid.
