Abstract (en)
A method of transferring flowable concrete containing aggregate to a desired location at substantially constant rate without sharp variations in pressure and a power driven pump that may be used to carry out the method. The pump requires no valves, is highly abrasive resistant, has a high constant flow rate discharge due to not operating intermittently, and subjects the conduit or hose through which the concrete discharges to a minimum of strain as the concrete flows at a substantially constant rate therethrough with no sharp variations in pressure, and with minimum frictional resistance.
