The R35/40 FL-Z-DB16-W-SAE1.1/2-L is a high-performance external gear pump manufactured by Rickmeier in Germany, specifically designed for industrial lubrication and hydraulic systems. Its core advantage lies in its efficient delivery of high-viscosity media (such as lubricating oil, hydraulic oil, heavy oil, etc.), with a displacement range of 35–40 cm³/rev, a maximum flow rate of up to 400 L/min, and an operating pressure of up to 11 MPa. The pump features a modular design that supports customization with motors (three-phase asynchronous motors or single-phase AC/DC motors) to meet the demands of complex operating conditions.
Structural Design
Robust and Durable: The pump housing is made of gray cast iron (EN-GJS-400-15), and the gears and shafts are hardened through carburized steel treatment, making them resistant to high temperatures, high pressures, and corrosive media.
Low Maintenance Costs: The pump has no vulnerable seals or valves, and its end-face wear is automatically compensated, enabling ultra-long-term maintenance-free operation.
Reliable Sealing: It comes standard with radial rubber shaft seals (with options for mechanical seals or fluororubber seals), suitable for high-temperature and high-pressure environments.
Performance Advantages
Efficient Self-Priming: The short straight-flow channel design enhances suction efficiency, with an oil suction height of up to 5m, reducing the risk of idling.
Low Noise Operation: Optimized gear meshing technology reduces noise levels by 20% below industry standards.
Strong Vibration Resistance: Multi-component sliding bearing coating technology withstands shaft misalignment vibrations and supports dry running (for a limited time).
Functional Configurations
Integrated Pressure Relief Valve: The DB16 in the model number indicates the integration of a DN16 pressure relief valve with a pressure regulation range of 8–12 bar, protecting the system from overload.
Interface Standard: The SAE1.1/2 flange interface complies with American standard high-pressure pipeline connection requirements.
