Plusafeeder ECO G2 Gearchem Pumps

Plusafeeder ECO G2 Gearchem Pumps

This self-priming, external spur gear pump has 1/4-inch ports and will deliver flows up to 1.5 gpm. Maximum rated differential pressure for the pump is 175 psi. Designed for simplified maintenance, the pump may be quickly disassembled without the need to break piping connections. The G2 is designed for continuous duty use and can handle a wide variety of applications ranging from viscous to very thin clear, non-abrasive fluids. Pump housings are investment cast in a variety of corrosion resistant metallurgies, with adequate wall thicknesses for hydro testing. Housings are finish machined on precision CNC equipment. 

Metallic and non-metallic gears are machine generated. A variety of materials are available, and an existing pump can be quickly converted to satisfy different service conditions. Combination metallic and non-metallic gear sets allow the pump to handle low viscosity and non-lubricating fluids at standard motor speeds. This capability provides reduced noise levels and eliminates the need for larger pumps operating at reduced speeds. All gear materials are non-sparking for use with hazardous fluids.
