When using the F/FP 425, you are able to pump out 99.98% of a 55 gal drum leaving less than 1% residual. The pump has an integrated foot valve that is easy to close before taking the pump out of the container. Thus the backflow of fluid in the pump is captured, preventing it from being left in the barrel. This can save huge dollars on expensive media and saves additional cleaning and disposal costs when handling hazardous chemicals. The pump is available in stainless steel, polypropylene and hastelloy C. Metallic constructed pumps can be used in hazardous areas.
