General Information
Technical Data

M Pumps

  •  Single acting
  • Single air drive head
  • Pressures to 2,200 bar (31,900 psi)
  • They are suitable for use in zone 1, category 2G/2D IIC TX explosion-proof areas (Temperature class depending on medium temperature).

M pumps are single acting types with single air drive head. They are compact lightweight and feature rugged construction.

 

  • M4 to M12 pumps have aluminium bodies and stainless steel plungers. M22 to M189 have stainless steel bodies and plungers. All M pumps have polyurethane seals with Buna "N" O-rings, UHMWPE package and Viton O-rings for water service is available as option.
  • All M pumps are 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)
  • 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
  • Side inlet for single acting versions: Order code: M37(L) – S / M37(L)VE – S
  • External pilot port modification: (only available for M22 to M189 single acting, single air drive head types) Order code: M37 – DIR
  • Spring return and hand lever attachment: (modification only available for M22 to M189 single acting, single air drive head types) Order code: M37 – 01H
  • 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.
