It is widely known thal most pumps early failures are due to contaminated fluids. As a warranty cannot be issued for dirt related wear, we recommend a filter be used, which can reduce the degree of contamination to a permissible dimension in terms of the size and concentration of dirt particles.
Pipe cross-section should be sized so that fluid velocity does not exceed recommended values. Carefully consider the diameter reduction of the inlet
and outlet pipes or hoses at the connection point with fittings.
Rotation direction of definition: when standing before the pump with driving
shaft up with its projecting end towards the observer, the pump is rotating
clockwise in case of right-hand rotation “D” .The contrary will happen with
left-hand pumps “S”, keeping the same point of view.
