Italy Di Puma quantitative vane pump (DFP) 

 Description: Pump has a variety of displacement, can also be combined into a variety of displacement of the double-pump. 
 If the pump module assembly, easy maintenance, not removed from the loop. 
 Pump stator curve using the elliptic curve, with two pairs of inlet and exhaust ports, the radial structure can reduce the driving force of the rotor, reducing the wear and tear on the pump. 
 Pump rotor blades 12, helps to reduce vibration and reduce noise.
