1. Description and Operation.
1.1 The Model 5000 pump is a positive displacement gear pump constructed of 316 stainless steel, Teflon,
PEEK and or Carbon.
Special pumps may be constructed from 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 and Drive Housing Assembly via the magnetic
coupling. An exploded view is shown in Figure 1. Fluid enters the inlet port and is drawn into the cavity
plate by the negative pressure caused by the gear rotation within the cavity plate. The gear teeth then
move the fluid around the cavity plate walls to the discharge side of the cavity plate. At the mesh point,
fluid is prevented from flowing back to the inlet, and as a result, the fluid is forced out of the cavity
