Diaphragm pumps represent an advantageous
solution in terms of saving because, since they are air-powered, there is no need
for expensive electric flameproof systems. When using water inks, there is no risk
of foaming and, generally, they do not heat nor do they mechanically stress
the inks. Since there are no seals, bushes, ball-bearings etc., they have a long
durability and have no need of special servicing. |
