WORKING PRINCIPLE
The yellow colored portion at side indicates the liquid as it enters the suction port area of the casing and the area between the rotor teeth and corresponding concave area between the idler teeth. The two black arrows indicate the pump rotation and progress of the liquid.
Notice the progress of the liquid through the pump and between the teeth of rotor idler gear. Also, note how the crescent shape on the head divides the liquid and acts as a seal between the suction and discharge ports.
This illustration shows the pump in a nearly flooded condition just previous to the liquid being forced into the discharge port area. Notice how the gear design of the idler and rotor form locked pockets for the liquid to guarantee absolute volume control.
The view shows the pump in a completely flooded condition and in the process of discharging the liquid through discharge port. The rotor and idler teeth mesh, forming a seal equidistant between the both ports, forcing liquid out the discharge port.
ROTATION DIRECTION
The pumps are typically (when viewed from the shaft end) designed as clock-wise rotation; that is, the sucking mouth (inlet) is on the right and the discharge mouth (outlet) is on top side.
For reverse operation:
You can operate your pumps in both directions. However, changing rotation direction of the pump shaft changes the pumping direction of the liquid; that is you can use both mouths of your pumps as the sucking mount or the discharge mount. Otherwise, it may not be able to perform the bypass operation.
FLANGE POSITIONS
This pumps have casings that can be turned to eight positions. This allows ports to easly match piping. Relief valve must point to suction port in all cases.
