Product Description
Flow Solutions Division
DS-4614-F synthetic fluids are long-life food grade
lubricants specially processed for use as barrier and
buffer fluids for mechanical seals on rotating equipment
requiring excellent chemical stability and
compatibility.
DS-4614-F fluids are recommended for systems
operating in high and low ambient temperature
environments.
DS-4614-F synthetic barrier fluids meet 21 CFR
۱۷۸٫۳۵۷۰ requirements for lubricants with the possibility
of incidental food contact. These are authorized
by the USDA for use in federally inspected meat and
poultry plants (H-1). All are nontoxic, nonhazardous,
and contain no heavy metals.
