Abstract

The pump moves a liquid without disturbing the laminar flow of the liquid. The liquid can be passed from one grille to the other, always in the same direction, in the shortest distance possible to give high efficiency with silence. An inclined thin circular ramp (2) is used. The ends of the ramp are slightly chamfered to help entry into the liquid. The ramp keeps the liquid flow in a laminar manner and has a collar fixed to the ramp outer circumference to assist fluid flow. The collar is pref. machined integrally with the pump body.
