NOP TOP Series Trochoid Pump | TOP-11A TOP-12A | TOP-1ME75-12MA

LIC Hydraulic specializes in the NOP TOP Series, the industry benchmark for high-performance Trochoid Pumps. Utilizing a unique internal-gearing trochoid rotor set, these pumps—including the TOP-11A, 12A, 13A singles and the integrated TOP-1ME75-12MA motor units—provide a continuous, pulse-free flow of fluid. This makes them the ideal choice for high-precision lubrication and cooling in CNC machine tools. The TOP-1ME series, with its direct-drive motor integration, eliminates the need for couplings and alignment, offering a compact and maintenance-free solution for your industrial hydraulic and lubrication needs.

Technical Highlights

• Pulse-Free Delivery: The trochoid tooth profile ensures smooth volume transitions, eliminating hydraulic vibration and noise.

• Compact Motor-Pump Integration: The TOP-1ME75 unit saves over $40\%$ of space compared to traditional pump-motor assemblies.

• Exceptional Durability: Low sliding velocity between the inner and outer rotors leads to minimal wear even during $24/7$ operations.

• Superior Self-Priming: Engineered for rapid fluid pickup, making it highly reliable for machine tool sump suction.

Application Areas

• Machine Tools: Forced lubrication for spindles, gears, and tool cooling.

• Energy Sector: Oil circulation for generators and fuel supply for industrial burners.

• Manufacturing: Lubrication systems for high-speed textile and printing machinery.

Expert Maintenance Tips

• Check Motor Rotation: For integrated units like the TOP-1ME75-12MA, ensure the motor rotation matches the pump’s directional arrow. Incorrect rotation will prevent oil pickup and lead to internal dry-friction damage.

• Monitor Oil Temperature: To protect the internal seals and maintain optimal viscosity, ensure the operating fluid temperature remains within $-5\text{°C}$ to $80\text{°C}$.

• Prevent Cavitation: Ensure the suction line is fully sealed. Due to its high self-priming capability, any air ingress will cause foam in the lubricant and excessive noise in the TOP-12A unit.
