151 P uses an avant-garde technology which includes two
patents: The instant volumetric reversal of pneumatic motor, that means a
very low pressure drop during the reversal, and the simultaneous
adjustment of packings. This simultaneous adjustment, depending on the
wear, allows a longer life and a better perfomance of the unit. The piston
is hard chrome treated and all the parts in contact with the products are
in stainless steel. Very easy maintenance. Tungsten carbide valves. |
