Gear pumps / pump units: durable, variable and economical

RICKMEIER gear pumps and pump units perform a broad variety of tasks in a wide range of industrial applications: from lubrication circuits to pressure generation in hydraulic working systems or the transportation of liquids for oils and other flow media. In many applications, they work in the background, quietly creating the preconditions for reliable and problem-free operation of other machines. The gear pumps and pump units can be used in hazardous areas according to ATEX directive 2014/34/EU. Furthermore, essential series of our program can be delivered in the Eurasian Economic Union, as they are marked and certified accordingly with EAC or EAC Ex.
