The RICKMEIER R25/20 FL-Z-DB16-W-SAE1-R-P is an external gear pump from the R5 series launched by Germany's RICKMEIER company (founded in 1914), specifically designed for industrial lubrication systems and fuel delivery. Its modular structure supports customized interface adaptations, making it suitable for demanding environments such as marine vessels, heavy machinery, and high-pressure hydraulic systems. Its core advantages lie in its high wear resistance, long service life, and low maintenance requirements, complying with ATEX explosion-proof certification (2014/34/EU) and EAC safety standards.
This pump is a rotary positive displacement pump that delivers media through the disengagement and engagement of meshing gears:
Suction Phase: The volume increases on the side where the gears disengage, creating negative pressure to draw in the medium.
Delivery Phase: The medium is trapped in the interdental chambers and pushed towards the pressure side as the gears rotate.
Discharge Phase: The gears mesh and compress the chambers, forcing the medium out through the pressure-side outlet.
Key Reminder: Ensure the suction line is well-sealed to prevent cavitation caused by leaks or low liquid levels.
