SD pumps are double acting, single air drive head type. They are characterized by the same features as the S series, but
Pumps come standard with side inlet, bottom inlet not available
They have less pulsations and deliver approx. 50% more flow than the single acting S pumps.
Maximum air drive pressure 10 bar (145 psi)
The unregulated pilot port on all SD pumps not only provides better pressure control but is also the ideal place to install control instrumentation because of its small size, BSP 1/8”.
