Description

SD series air driven hydraulic pumps are high pressure reciprocating plunger pumps of double acting, single air drive head model. Air drive pressure from 1bar (*4.5 psi) to 8bar (**6 psi) maximum. Operating pressure up to1, **0 bar(*7, **0 psi).
They are characterized by the same features as the S series, but they have less pulsations and deliver approx.*0% more flow than the single acting S series ***** are suitable for powering a variety of liquids.
