Description
Several of our rotor types are offered in two different designs. They are the open-end and closed-end (shrouded) rotor designs. With the open-end design, the blades are welded directly to the rotor shaft. With the closed-end (shrouded) design there are additional discs welded to the shaft and blade ends. Each design has application advantages and disadvantages. Explore the various rotor types we offer below.
Types of Rotors
The Type “A” rotor is used for the majority of applications. It has deep pockets. Hence, it has the maximum volumetric capacity. This rotor is used for either air locking or feeder applications. Type “A” rotors have the lowest air or gas leakage and is the least expensive to build. The Type “A” rotor is good for handling free flowing to slightly cohesive products with narrow particle sizes distribution. It’s not the best for handling any abrasive products.
The Type “AS” rotor has deep pockets and a closed ends. This rotor is used for either air locking or feeder applications. It is better for handling products having a wide particle. Because of the shroud plate it is better for handling slightly abrasive products. The Type “AS” rotor is not the best for handling cohesive materials.
The Type “B” rotor is designed with filled rotor pockets. This rotor is used for feeder applications where the valve flanges need to match a set size of inlet and outlet. The Type “B” rotor is good for handling free flowing to slightly cohesive products.
The Type “BS” rotor has filled rotor pockets and closed end design. This rotor is used for feeder applications where the valve flanges need to match a set size of inlet and outlet. The Type “B” rotor is better for handling slightly cohesive products.
The Type “C” rotor is used for metering feeding applications. It also is designed with filled rotor pockets. However, the pockets are shallower than a Type “B” rotor. This rotor is used for feeding difficult flowing cohesive products. The shallower pockets aid in the discharge of the cohesive materials.
The Type “CS” rotor is designed with filled rotor pockets and shrouded ends. The pockets are shallower than a Type “BS” rotor. This rotor is used for feeding difficult flowing cohesive and slightly abrasive products. The shallower pockets aid in the discharge of the cohesive materials.
The Type “D” rotor has adjustable tips. This rotor is used for either air locking or feeder applications. It can be furnished with filled pockets similar to the “B” and “C” rotor types. The tips can be adjusted to compensate for rotor tip wear. When flexible tip material is used, the type “D” rotor is the best rotors to use when handling fibrous material.
The Type “DS” rotor has adjustable tips with closed ends. This rotor is used for either air locking or feeder applications. With the end shrouds and adjustable tips, this rotor is a good choice for handling slightly abrasive products. The tips adjustment can compensate for rotor tip wear. When Urethane flexible material is used, the type “DS” rotor is the best rotor to use when handling fibrous material that is somewhat abrasive.
The Type “D3” rotor has adjustable tips and ends. This rotor is used for either air locking or feeder applications. The Type “D3” rotor is the best rotor to use when handling fibrous material. The tips can be adjusted to compensate for rotor tip and end wear.
