High Pressure Pumps – S…D series

  • double acting
  • single air drive head
  • Pressures to 1,000 bar (14,500 psi)

MAXIMATOR pumps S series are available as single or double acting with single air drive head.

S…D pumps

  • double acting
  • single air drive head
  • Pressures to 1,000 bar (14,500 psi)

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”.

Options for S series

  • Special inlet and outlet ports (i. e. NPT): Order code: S35(D) – NPT
  • Special seal material to handle special fluids: Order code: See fluid compatibility guide
  • Air control unit for S series with filter pressure regulator, control pressure gauge and shut-off valve: Order code: S35(D) with C1.5
  • Other options available on request.
