Reciprocating asymmetric baffles in a pipe can produce a time averaged pressure difference and hence can be used to form the basis of a valveless pump.

This report describes the production of characteristic curves of head versus flow rate for a range of variables in a 50.8 mm I.D. tube agitated by reciprocated asymmetric baffles. The effect of amplitude and frequency of oscillation on the pumping of tap water is reported. Baffle length and fitting of arifices to the pump are two other modifications considered. The pumping characteristics for two fluids other than tap water, namely glucose and a filter pulp slurry, are also described.
