1. Description and Operation
1.1
The Model 5500 pump is a positive displacement gear pump constructed of 316 stainless steel, PEEK
or Teflon, and Viton.
Special pumps may be constructed of alternate materials. The pump is magnetically driven and is therefore
leak-proof and contamination free. The pump is self priming under normal conditions.
1.2 Drive power for the pump is provided by the motor via the magnetic coupling. An exploded view is
shown in Figure 1. Fluid is drawn into the pump due to the negative pressure created by the gear
rotation in the cavity plate. The fluid is contained by the gear teeth, cavity walls, and gear mesh to
create fluid transfer and pressure.
