Peristaltic pump and bearing arrangement therefor |
摘要 |
A peristaltic pump having a nonmetallic housing supporting an internal rotor which carries compression rollers for cooperation with a compressible flow tube looped internally of the housing so as to effect a peristaltic pumping action on the tube during rotation of the rotor. The rotor is of unitary construction and is made from a nonmetallic material. The rotor contains hub projections which are directly journaled within bearing surfaces formed within the housing, and rotatably suports at least one nonmetallic compression roller through a tubular open ended metal support shaft which enables air flow through the support tube to provide improved heat transfer during operation.
