AZPF Hydraulic Gear Pumps

The gear type pump is the most widely used design in hydraulic systems. It is simple in construction, reliable in operation, performs with a variety of fluids and is the most cost effective way of generating hydraulic pressure. Bosch has been involved in the design, development and manufacture of gear pumps for many years and is one of the largest manufacturers of quality gear pumps in the world. 


Gear Pumps: 
• Flows from 1.85 gpm to 13.18 gpm @ 1750 rpm 
• Pressures to 3625 psi continuous 
• Continuous speeds from 500 to 3500 rpm 
• Overall efficiencies from 85 to 92%
• Pump bodies built from extruded aluminum with cast iron end covers form a very high strength unit 
• DU bearings are standard ensuring long life
