• Features

Highly Integrated Design, Space Saving
Integrates the high-pressure pump, filtration system, and related functions into a single unit. Installation footprint is only about 25% of conventional high-pressure systems and can be directly installed inside the machine coolant tank, reducing space requirements and piping complexity.
Improved Machining Efficiency
Through high-pressure through-tool coolant delivery, coolant is supplied directly to the cutting zone, improving chip evacuation, cutting performance, and overall machining efficiency for a wide range of machine tool applications.
High Pressure Output for Stable Cutting
Designed with a high-pressure plunger pump structure, capable of delivering up to 70 kg/cm² (approximately 69 bar), making it suitable for deep-hole machining, high-speed machining, and precision cutting applications while ensuring stable and reliable coolant supply.
Energy-Saving Servo System Integration
Compatible with inverter motors or servo motors. Flow rate and pressure output can be automatically adjusted according to machining requirements, reducing energy consumption and creating a highly efficient servo through-tool coolant system.
High-Precision Filtration
Standard configuration includes a 400 Mesh (38 μm) filtration system, with optional filtration up to 800 Mesh (18 μm), effectively reducing contaminants entering the system and improving operational stability.
Durable and Reliable, Lower Maintenance Costs
Manufactured with high-quality components and precision engineering. Combined with an automatic sludge discharge design, it reduces filter replacement frequency and maintenance costs while maximizing overall investment value.
Wide Range of Applications
Suitable for CNC lathes, milling machines, grinding machines, CNC machining centers, deep-hole drilling equipment (Gun Drilling), high-speed machining equipment, and various through-tool coolant systems. It can also be applied to energy-saving servo hydraulic systems and industrial hydraulic equipment.
