High Pressure Pumps - G series

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 pumps

• single acting
• single air drive head
• Pressures to 4,500 bar (65,295 psi)

G pumps have stainless steel bodies and plungers. All G pumps have polyurethan seals. For strictly water service, UHMWPE seal option is recommended. This seal is an option because the standard polyurethane seal provides significantly better service life in non-straight water applications. G pumps come standard with bottom inlet. Side inlet is available as option. Model G500(S) is only available with side inlet.

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.)
• Other options available on request.
