The miniature “H” Series Pump Heads from Fluid Metering, Inc. (Syosset, NY) are now available with an isolation gland to provide a fluid barrier between the pumped process fluid and atmosphere. These pumps are ideal for maintenance-free dispensing of saline based reagents, slurries, abrasive fluids, inks, anaerobic fluids, and much more. Isolation gland pumps have a pair of extra ports which are connected to a fluid source (either liquid or gas). The fluid flowing through the gland ports provides a barrier which isolates the pumped process fluid from the seal area and atmosphere. The isolation gland is easily connected to the “barrier” liquid or gas source via barbed fittings.
