Hydraulics from a single source
FPS Hydraulik GmbH from Holdorf in the Oldenburg Münsterland region designs, manufactures and tests custom hydraulic power units to drawing or specification with drive power ratings from 0.25 to 100 kW and operating pressures up to 700 bar. The portfolio includes hydraulic control and valve blocks built to circuit diagram, in-house manufacture of the AgriProof 60/210 Pro implement test bench for agricultural machinery workshops (60 l/min at 210 bar, 730 Nm PTO) as well as retrofit and modernization of existing systems, servo valve repair, hydraulic accumulator service and cylinder overhauls. Components are sourced independently of manufacturer from Bosch Rexroth, Parker, Bucher, Danfoss and HYDAC; control blocks are milled at partner companies and assembled and tested in-house. Every power unit undergoes testing on the company's own test bench before delivery, with a test report. Full documentation with circuit diagram per DIN ISO 1219, STEP model, bill of materials and connection information is part of the delivery. Customers come from mechanical engineering and agricultural machinery; the on-site service with pipe bending machine serves the surrounding area in Lower Saxony.

Components and methods
Circuit diagram standard for hydraulics
All delivered circuit diagrams are fully drawn with component identification per DIN ISO 1219.
3D data exchange
Every power unit and every control block is delivered as a STEP model so that the components can be integrated into the customer's assembly before manufacturing.
Hydraulic accumulator service
Precharge pressure measurement, nitrogen filling and bladder or accumulator replacement with own test and filling equipment, inspection per BetrSichV as a competent person up to 1,000 bar·l.
