Drive Plate - Titanium
This component is manufactured from aircraft grade titanium. This part is a structural component that allows for a three piece wheel. A three piece wheel allows for the easier access of the lower wear ring to be removed.
The two o-rings on the drive plate plus an o-ring between the ceramic lower wear ring and the case are added to the drive plate to allow for the ceramic lower wear ring to float during operation.
Ceramic Lower Wear Ring-Titanium
This wheel design allows for a one piece ceramic lower wear ring that is contained with a titanium ring with an engineered interference fit. The titanium containment ring keeps the ceramic wear insert under compression during operation. Titanium material is used to prevent the chance of stress corrosion cracking. The design incorporates a stepped area with an o-ring seal between the ceramic lower wear ring and cone nut. This design prevents the slurry from reaching the stem of the drive plate and migrating underneath the ceramic lower wear ring.
The cone nut is manufactured from hardened stainless steel. The design incorporates a stepped area with an o-ring seal between the ceramic lower wear ring and cone nut. This design prevents the slurry from reaching the stem of the drive plate and underneath the ceramic lower wear ring.
This component is manufactured from aircraft grade titanium. This part is a structural component of the three piece wheel design. The design allows for the use of advanced wear materials for the upper and lower wear rings. The case is symmetrical for easy one hundred and eighty degree rotation of the nozzles and allows for even wear on the outside diameter of the case.
This nozzle has a larger orifice help with plugging issues and higher slurry densities. The nozzle was designed to include a stepped area with an o-ring to prevent slurry packing around the nozzle allowing for easier removal. This nozzle incorporates a titanium cup. The previous design utilized a taper to hold the nozzle in place during operation. The centrifugal forces during operation wedged the nozzle with the tapered design in the main body of the atomizer wheel making difficult if not impossible to remove without breaking. With the new design the nozzle is able to be removed and rotated for longer wear life of the component.
The o-ring on the case plus the two o-rings incorporated in the lid allow for the upper wear ring to float during operation.
Separate Upper Wear Ring
In other designs, the lid acts as a structural component as well as a wear component. The wheel is designed to allow for RPM’s patented upper wear ring design. This design separates the lid as a structural component and the upper wear ring as a wear component. The upper wear ring wear insert can be offered as a heat treated stainless steel or ceramic for extreme wear applications. The wear insert is contained with a titanium ring for superior corrosion resistance.
This component is manufactured from aircraft grade titanium. This patented design allows for the lid to be a structural member only and the upper wear ring becomes the main wear component.
