Rim for securing a pump to a tank
A retaining ring for securing a pump to a tank. The ring has a circular body with an outer dimension selected to surround a pump opening in the fuel tank. An interior opening has a diameter that is selected to contact a portion of a pump housing that is placed in the tank. The retaining ring is fastened or attached directly to the tank.
1. A retaining ring for securing a pump to a container, the retaining ring comprising:
a circular body having an outer portion with an inner diameter dimensioned to surround a pump opening in the container, and a radially extending inner portion that is connected to the outer portion and defines an opening with a diameter that is less than the pump opening and dimensioned to contact a pump housing dimensioned to fit within the pump opening;
the radially extending inner portion has a plurality of apertures that are defined adjacent to the outer portion of the circular; and
the outer portion is secured directly to the container.
2. A retainer for securing a puma to a container having an existing pump securing structure, the retainer comprising:
a unitary circular body having an outer ring with a first diameter that includes a plurality of apertures for fastening the outer ring to the container; an inner ring with a second diameter that is less than the first diameter and is selected to contact a portion of a pump housing; and, a radially extending intermediate portion that connects to the outer ring and the inner ring portion;
wherein the radially extending intermediate portion defines a plurality of apertures that are positioned to pass over the existing pump securing structure when the outer ring secured directly to the container.
3. The retaining ring of claim 2 wherein, the outer portion is in a first plane and the inner portion is in a second plane.
4. The retaining ring of claim 3 wherein, the first plane and the second plane are parallel planes.
5. The retaining ring of claim 3 , wherein the intermediate portion in angularly disposed between the first plane and the second plane.
6. The retaining ring of claim 2 wherein, a section of the intermediate portion between apertures is separated from the outer portion.
7. The retaining ring of claim 2 wherein, the outer portion has a plurality of fastener apertures.
8. The retaining ring of claim 2 further comprising a seal for the outer portion.
9. A retaining ring for securing a pump to a container having an existing pump securing structure, the retaining ring comprising:
a unitary circular body having an outer portion having a dimension larger than the container opening to surround the tank opening, an inner portion dimensioned to engage a portion of a housing associated with a pump located in the container opening, and a radially extending intermediate portion that extends between the outer portion and the inner portion;
wherein the radially outer portion is secured directly to the container independently of any existing pump securing structures.
10. The retaining ring of claim 9 wherein, the radially extending intermediate portion defines a plurality of apertures between the outer portion and the inner portion.
11. The retaining ring of claim 10 wherein, the plurality of apertures between the outer portion and the inner portion are uniform.
12. The retaining ring of claim 10 wherein, a relief is formed in the outer portion to define a cantilevered section in the intermediate portion.
13. The retaining ring of claim 10 wherein, the outer portion has a plurality of fastener apertures.
14. The retaining ring of claim 10 further comprising a seal for the outer portion.
15. The retaining ring of claim 10 wherein, at least one section of the intermediate portion is cantilevered from the inner portion.
