Drum pumps constructed of plastic (polypropylene, ethylene and pvc) exhibit excellent resistances to detergants, caustic, acids, alkali's
and inorganic water soluble media. Also suitable for handling liquid foods to prevent contamination.
Pumps constructed of stainless steel resist aggressive media such as solvents, hydrocarbons, turpene's, oils and flammable media.
Thermoplastics such as PTFE and PVDF are innately superior in their resistances to corrosive and aggressive chemicals than any other material.
