Basic Performance
Displacement: 16 cm³/rev (displacement per revolution), classified as a small-displacement pump in the R25 series.
Item Number: 474016
Seal Type: The "Z-SO" designation indicates a fluororubber (FKM) oil seal, which is resistant to high temperatures (≤120℃) and chemical corrosion, suitable for media such as lubricating oils and fuels.
Interface Standards: By default, it features a right-hand rotation design (if the model does not indicate "L," it is right-handed). The oil inlets and outlets can be optionally equipped with G1 threads or SAE flanges (customization required).
Structure and Materials
Housing: Gray cast iron (standard version) with a lightweight design, balancing heat dissipation and corrosion resistance.
Core Components: The gears and drive shaft are made of hardened carburized steel, with precision-ground surfaces to enhance wear resistance by over 30%.
Bearings: Composite material slide bearings with dry running tolerance (no seizure during short-term oil-free operation).
Design Features and Advantages
Efficient Self-Priming and Low-Noise Operation
Self-Priming Capability: It can achieve a self-priming height of up to 5 meters under negative pressure conditions, starting without pre-filling liquid and reducing the risk of cavitation.
Low-Noise Design: Optimized gear tooth profiles for meshing, with operating noise ≤70 dB(A), suitable for environments requiring quiet operation (such as laboratories and indoor workshops).
Long Service Life and Low Maintenance
No Vulnerable Valves/Seals: The modular three-part structure reduces maintenance points, with a theoretical maintenance cycle of ≥5000 hours.
Seal Reliability: The fluororubber oil seal is compatible with media such as waste oil (ATF), hydraulic oil, and diesel, extending the anti-leakage lifespan by 50%.
Flexible Adaptability
Supports flexible coupling installation with buffering to compensate for drive shaft deviations (±0.5°); can be adapted to various drive sources such as electric motors and hydraulic motors.
Application Scenarios
Applicable Media:
Industrial Fluids: Lubricating oils, gear oils, hydraulic oils, cutting fluids, waste engine oils, diesel, etc. (requiring lubricity, with a viscosity range of 10–300 cSt).
Prohibited Media: Media containing hard particles or strong acid/alkaline solutions (unless customized with a stainless steel version).
Industry Sectors:
Manufacturing: Coolant circulation in machine tools and lubrication systems in automotive production lines.
Energy Equipment: Fuel delivery in small generator sets and lubrication in wind turbine gearboxes.
Construction Machinery: Hydraulic oil pumps for mobile equipment (such as forklifts and excavators).
Chemical Assistance: Metering and delivery of low-corrosive solvents (compatibility with the medium must be confirmed in advance).
