Fluid Metering (Syosset, NY) has introduced its low-volume valveless metering pump for precision dispensing of air-sensitive, crystal-forming fluids. These “H” Series pump heads are now available with an isolation gland to provide a fluid barrier between the pumped process fluid and atmosphere. They include a pair of extra ports that are connected to a fluid source (either liquid or gas). The fluid flowing through the gland ports provides a barrier that isolates the pumped process fluid from the seal area and atmosphere. The isolation gland is connected to the “barrier” liquid or gas source via barbed fittings.
