CP Series Hydraulic Gear Pump | CP0, CP1, CP2 | Injection Moulding Machine Pump

CP Series High-Performance Silent Internal Gear Pumps for Injection Moulding Machines

Product Overview: The CP Series is the power heart of hydraulic systems for injection moulding machines. As high-performance internal gear pumps, this series is specifically engineered to meet the stringent demands of high pressure (Rated 25-31.5 MPa) and ultimate operational smoothness in the moulding process. Our range features core models: the CP0, CP1, and CP2 base series, including technical specs like CP1-25-P-10R-36 and the heavy-duty CP2-100-P-10R. Its unique three-stage meshing principle ensures exceptional pressure stability and minimal noise even under variable-speed servo-drive conditions.

Key Technical Advantages:

• Ultra-Quiet & Low Pulsation: Featuring an optimized internal gear profile, operational noise levels are significantly lower than traditional external pumps. Minimal pressure ripples drastically extend the life of hydraulic lines and precision servo valves, enabling accurate injection control.

• Perfect Match for Servo Drives: Exceptional low-speed stability (stable high pressure even at 10-50 RPM) matches servo motor dynamics perfectly, significantly enhancing the energy efficiency of the machine.

• Dual Gap Compensation: Equipped with automated axial and radial pressure compensation mechanisms. Even during long-term high-pressure clamping cycles, it maintains a volumetric efficiency above 95%, effectively minimizing oil overheating.

• 100% Direct Replacement: Models like CP1-20/25/32/40 adhere strictly to international flange and shaft standards. Suffixes like P-10R guarantee that mounting interfaces, rotation, and displacements match original systems seamlessly.

• Target Applications: All-electric and hybrid injection moulding machines, ceramic presses, CNC bending machines, and die-casting machinery.
