A hydraulic pump is the heart of every hydraulic system. Our pumps have 3-bolt or 4-bolt mounting flanges and shafts in UNI and DIN standard. With a special pump adapter (available in our offer) it is possible to reverse the standard e.g. from DIN to UNI.
PRESKO gear pumps are made of made of the highest quality materials, that allow many years of trouble-free operation of the entire system. Such pumps are used in top brand cars such as Volvo, Scania, Renault, Iveco, Mercedes, Man, Daf, Star, Kamaz, Jelcz, Liaz.
We sell pumps with a displacement of 40 l, 50 l, 60 l, 80 l, 112 l. The pressure resistance is 250 bar (40 l and 50 l) and 230 bar (60 l and 80 l).
All our pumps can work two-ways.
Please contact us to select the appropriate gear pump for your application.
