High Pressure Pumps – G…-2 series

  • single acting
  • double air drive head
  • pressures up to 7,000 bar (101,000 psi)

MAXIMATOR pumps G series are available as single or double acting with either a single or double air drive head. For air drive pressures of 1 bar (14.5 psi) minimum to 10 bar (145 psi) maximum. The unregulated pilot port on all G pumps not only provides better pressure control but is also the ideal place to install control instrumentation because of its small size, 1/8 BSP.

G…-2 pumps

  • single acting
  • double air drive head
  • Pressures to 7,000 bar (101,000 psi)

G…-2 pumps are single acting double air drive head pumps. Compared with the single acting single air drive head G pumps they reach double pressure at the same air drive pressure.

G…-2 pumps are available with polyurethane seals, UHMWPE seals with Viton O-ring for water use are available as option. They come standard with bottom inlet, side inlet is available as option. For air drive pressures from 1 bar (14.5 psi) minimum to 10 bar (145 psi) maximum.

Options for G series

  • Seal material for oil use (standard pump): Order code: G35 – (L)
  • Seal material for water use: (not available for G500 and G500-2) Order code: G35 – (L)VE / G37D – VE
  • Special seal material to handle special fluids: Order code: See fluid compatibility guide
  • Side inlet (G500, G500-2 and G60 – G150 come standard with side inlet) Order code: G35(L) – S / G35(D)VE – S
  • Special inlet and outlet ports (i. e. NPT): Order code: G35 – NPT
  • Air control unit for G series with filter pressure regulator, control pressure gauge and shut-off valve: Order code: G35(L) with C2
  • To protect the pump against excessive outlet pressures, an air safety valve can be fitted to the air control unit: Order code: G35(L) with C2/SVair (The outlet pressure has to be indicated.)
