This document is a technical parameter table for gear pumps, which includes information such as flow, pressure, temperature and speed.
This document is a technical datasheet for a complete assembled and tested two-stage gear pump manufactured by Rickmeier GmbH. The unit combines an R35/86 stage with an R35/50 stage, configured according to specific SAE2 connection standards without counterflanges.
The data sheet provides detailed operational parameters such as oil flow rates (110 dm³/min for the first stage and 71 dm³/min for the second), pressure rise capabilities, and maximum fluid temperature limits of +120°C. It also lists material specifications for the casing and gearshafts, along with contact information for the manufacturer. This manual is written in German.
