1. The slotted rotor is eccentrically supported in the cycloid cam. The rotor is located close to the cam wall, thus forming a crescent-shaped cavity. The rotor is sealed into the cam by two side plates. The blade or blade is installed in the slot of the impeller. When the rotor rotates (yellow arrow) and fluid enters the pump, centrifugal force, hydraulic pressure, and / or push rods push the blades towards the wall of the housing. The tight seal between the blade, rotor, cam and side plate is the key to the good suction characteristics shared by the blade suction principle.
2. The casing and cam press the fluid into the pump chamber through the holes in the cam (the small red arrow at the bottom of the pump). The fluid enters the pocket formed by the blades, rotor, cam and side plates.
3. When the rotor continues to rotate, the blade sweeps the fluid to the other side of the crescent. When... أقل
