General Information
Technical Data

M...-3 Pumps


  • Single acting
  • Triple air drive head
  • Pressures to 4,000 bar (58,000 psi)

M...-3 pumps are single acting triple air drive head pumps. Compared with the single acting single stage M pumps they reach triple pressure at the same air drive pressure.


M...-3 pumps are available with polyurethane seals. They come standard with bottom inlet, side inlet is available as option.


Options for M series


  • Seal material for oil use (standard pump): Order code: M37 – (L)
  • Special seal material to handle special fluids: Order code: See fluid compatibility guide
  • Side inlet for single acting versions: Order code: M37(L) – S / M37(L)VE – S
  • 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
