This is the mobile vehicle mounted range of O series pumps most commonly used for aircraft refueller vehicle applications. In order to achieve the high pressures required the PTO driven versions of the pump use a simple gearbox to increase impeller speed. The gears are helical type to reduce noise. Most PTO models are available in both anti-clockwise and clockwise rotation. The 6” and 8” pumps are also available as ‘split shaft’ or ‘in line’ versions to be driven via the prop shaft. The 3” hydraulic motor driven pump does not have a gearbox. It is a very simple and compact unit capable of flows up to 1600 L/min.
