S...D 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 S...D 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".

- Special seal material to handle special fluids: Order code: See fluid compatibility guide
