ARO 637348-C4D Service Kit for AF Series Piston Pumps
Five-component service kit with V packing, U-cup, O-ring, bowed washer and internal retaining ring.
ARO 637348-C4D is the five-part 637348 kit: V packing, U-cup, O-ring, bowed washer and retaining ring for AF1044S11FF47-1 and AF0828S11FF47 pumps.
The ARO 637348-C4D Service Kit is the shorter of the two 637348 kits in our catalog. Per its spec notes, it holds five kinds of parts: V packing, a U-cup, one O-ring, a bowed washer and an internal retaining ring. Materials for these pieces are not given in our data, and the C4D suffix is the code that sets this kit apart.
V packing and U-cups are lip seals. They seal against a moving rod, and the bowed washer keeps light spring load on the stack. The retaining ring holds the assembly in its bore.
When to Use This Kit
- Fluid weeps past the rod seals during each stroke.
- The pump creeps or cycles when it should be stalled against a closed outlet.
- The packing has been in service a long time and the pump is apart for other repairs.
