I. Company Background
• Company Name: Nippon Oil Pump Co., Ltd. (NOP)
• History: Over eighty years of experience in oil pump research, development, and production
II. Product Features
• Core Technology Products: Trochoid Gear Pumps and Orbmark Hydraulic Motors
• Features of Trochoid Gear Pumps:
• Compact Size: Space-efficient design suitable for installations with limited space.
• Low Noise: Reduced impact from trochoid gear meshing results in significantly lower operational noise compared to conventional gear pumps.
• High Durability: Wear-resistant casing and high-precision gears ensure a lifespan of tens of thousands of hours.
• Wide Application Range: Ideal for continuous or intermittent low-pressure lubrication in lubrication systems, particularly suited for machine tools, textile machinery, printing machinery, and light industrial machinery.
• Features of Orbmark Hydraulic Motors:
• High Torque and Rapid Response: Manufactured under license from Orbmark USA, these motors offer high torque and rapid response capabilities.
• Compact Size: Smaller than other motors with the same displacement, enabling low-speed, high-torque operation.
• Strong Load-Bearing Capacity: Easy to start, stop, reverse, and operate at high speeds. Low torsional inertia allows for sustained high-speed operation.
III. Product Line and Applications
• Product Line: Over 380 models covering lubrication pumps, fuel pumps, cooling pumps, etc., catering to diverse industrial needs.
• Application Fields: Widely used in industries such as aviation, shipbuilding, automotive, machine tools, pharmaceuticals, chemicals, and industrial machinery.
• Examples of Specific Models:
• TOP-N350HLVB: Belongs to the NOP Trochoid Gear Pump series, featuring compact size, high durability, and low noise. Designed specifically for lubrication systems, it supports continuous or intermittent low-pressure oil supply.
• TOP-216HWMVB: Suitable for cooling cutting fluids and high-pressure water systems in machining centers. It features an integrated three-phase motor design and is compatible with both water-soluble and oil-based cutting fluids.
IV. Technical Parameters and Performance
• Flow Rate and Rotational Speed: For example, the TOP-N330HVB has a displacement of 39 cm³/rev. At a rotational speed of 1800 rpm, its theoretical flow rate can reach 70.2 L/min, making it suitable for lubrication or hydraulic systems requiring medium to high flow rates.
• Pressure Range: Standard trochoid pumps have a maximum pressure of ≤10 MPa. High-pressure models (such as the TOP-N350HLVB) can adapt to higher-pressure conditions through optimized tooth profiles and seals. The TOP series high-pressure models typically have a maximum pressure of ≤16 MPa (with original factory technical support).
• Temperature Range: The cast iron body combined with aluminum alloy die-castings can withstand a working temperature range of -5°C to 80°C.
• Filtration Accuracy: It is recommended to use a filtration device (with a filtration accuracy of ≤50 μm) to extend the lifespan of the pump.
