New pump easily handles air sensitive, crystallizing fluids

Fluid Metering Inc. has developed a low-volume valveless metering pump for precision dispensing of air sensitive, crystal forming fluids. The company’s 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 suited for maintenance-free dispensing of saline based reagents, buffers and wash fluids, slurries, abrasive fluids, fluids with particulates, inks, pigments, anaerobic fluids, and dialysate used for hemodialysis.

New pump easily handles air sensitive, crystallizing fluids

Fluid Metering Inc. has developed a low-volume valveless metering pump for precision dispensing of air sensitive, crystal forming fluids. The company’s 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 suited for maintenance-free dispensing of saline based reagents, buffers and wash fluids, slurries, abrasive fluids, fluids with particulates, inks, pigments, anaerobic fluids, and dialysate used for hemodialysis.

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.
The pump heads can be configured with all of the company’s drive options, including ac, dc, hazardous duty, pneumatic and stepper, as well as programmable dispensing systems.
