FMI Metering PumpFluid Metering Inc.’s Low Volume Valveless Metering Pump is for precision dispensing of air-sensitive, crystal-forming fluids. Miniature “H” Series Pump Heads are now available with an isolation gland to provide a fluid barrier between the pumped process fluid and atmosphere. These pumps are a good fit for maintenance-free dispensing of saline-based reagents, buffers and wash fluids, slurries, abrasive fluids, fluids with particulates, inks, pigments, anaerobic fluids, dialysate used for hemodialysis, and more. Isolation gland pumps have 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 via barbed fittings. The “H” Series Pump Heads can be configured with all of FMI’s drive options, including AC, DC, hazardous duty, pneumatic and stepper, as well as programmable dispensing systems. – fmipump.com
