Reversible Hydraulic Pump ø82.5 SAE-AA FLANGE – Group 2

Features and functions

The flange of this model has a diameter of 82,5 mm. Reversible products are used for some special applications and their rotation verse is alternately clockwise and counterclockwise. Therefore, if you are looking for a pump that must work with a single rotation verse clockwise or counterclockwise (possibly to be reversed according to your needs before mounting the product in the application), we recommend our unidirectional hydraulic pumps, whose rotation verse can be changed without adding any components: go to the page of unidirectional pumps of group 2. This model is also available with cast iron flange.
