Self-coupling flange on support foot

摘要

The pump assembly is designed to attach itself to a baseplate etc. There is a coupling foot (16) which may be engaged by pins on the pump body. The pins have a small diameter cylindrical portion adjacent to the pump body and have conical ends which taper outward to a larger diameter. The pins on the pump lie in the same horizontal plane and engage with half-round slots at the top of a coupling flange (34) on the coupling foot.
