This hand-operated Rheinstrom sewage pump M 50 FA is a hardwearing manual pump and very suitable for the transportation of excrements. A long operating life is guaranteed due to the use of long lasting and high quality materials (red brass and aluminium). The main-features are the same as the ones of the sewage pump M because the suction connections can also be rotated or exchanged. Attention: The cross section of the pipe should never be less than 1 ½“/ 38 mm – or the pump capacity will not be achieved.
