MO pumps

  • single acting
  • single air drive head
  • Pressures to 1,000 bar (14,500 psi)

MO pumps are single acting types with single air drive head. They are lightweight, rugged and are available in several pressure ratios.

  • Cast iron bodies, tool steel plungers and polyurethane seals.
  • Pumps come standard with bottom inlet
  • Ideal for portable power packs
  • For air drive pressure from 1 bar (14.5 psi) to10 bar (145 psi) maximum.
