EnviroGear pumps are suitable for chemical product-transfer applications, such as the transfer of resins, including those that contain dicyclopentadiene (DCPD), styrene and methylmethacrylate (MMA). Since many of the chemicals used in resin production are flammable and hazardous to health, any amount of product leakage during their handling and transfer, or their components, cannot be tolerated. The EnviroGear range has a magnetically driven seal-less design, which eliminates the seal failures that can hamper these types of operations. There is a one-fluid-chamber design, which features only seven primary parts and an optimized cooling path and a patented Eccentric Spindle, which provides between-the-bearing support with no corresponding cantilever load.
The EnviroGear line of internal gear pumps are constructed of carbon steel, ductile iron or stainless steel with flow rates to 200 gpm (757 lpm) at a maximum of 640 rpm. They have a differential-pressure range of 20 to 200 psi (0 to 13.8 bar), can operate in temperatures from -40°F to 500°F (-40°C to 260°C) and can handle product viscosities from 0.5 to 50,000 cst.
