High Pressure Pumps – M…D series

  • double acting
  • single air drive head
  • Pressures to 2,200 bar (31,900 psi)

MAXIMATOR pumps M series are available as single or double acting with either a single, double or triple air drive head. For air drive pressures from 1 bar (14.5 psi) minimum to 10 bar (145 psi) maximum.

M…D pumps

  • double acting
  • single air drive head
  • Pressures to 2,200 bar (31,900 psi)

M…D pumps are double acting, single air drive head type. They are characterized by the same features as the M series, but

  • they have less pulsations and deliver approx. 50% more flow than the single acting M pumps
  • All M…D pumps come standard with side inlet, bottom inlet not available

Options for M series

  • Seal material for oil use (standard pump): Order code: M37 – (L)
  • Seal material for water use: (not available for M …-2/M…-3 and M …-01H types) Order code: M37 – (L)VE / M37D – VE
  • Special seal material to handle special fluids: Order code: See fluid compatibility guide
  • Special inlet and outlet ports (i. e. NPT): M37 – NPT
  • Air control unit for M series with filter pressure regulator, control pressure gauge and shut-off valve: Order code: M37 with C1
  • To protect the pump against excessive outlet pressures, an air safety valve can be fitted to the air control unit: Order code: M37 with C1/SVair
    (The outlet pressure has to be indicated.)
  • Other options available on request.
