CP0-10-P-10R SUNNY Internal Gear Pump 35MPa

Product Overview

The CP0-10-P-10R is a SUNNY / HYTEK CP0 Series fixed-displacement internal gear pump designed for compact industrial hydraulic systems, auxiliary power units and servo-oriented hydraulic applications.

Publicly available CP Series information identifies CP0, CP1 and CP2 as internal gear pump families, with CP0 representing the compact, small-displacement group. The series is promoted for low noise, low flow and pressure pulsation, and pressure-compensated operation.

The CP Series uses an axial and radial pressure-compensation concept intended to control internal clearances and maintain volumetric performance under changing operating conditions. Public application information highlights injection molding machines, shoe machinery, die-casting equipment, forklifts and servo frequency-conversion hydraulic systems.

For CP0-10-P-10R, the currently indexed public sources confirm the model family and configuration but do not provide sufficient evidence to state an exact model-specific displacement, weight or complete dimensional drawing with confidence. Those values should therefore be verified against the actual nameplate or matching technical document before procurement.

For replacement applications, we focus on in-place dimensional and functional interchangeability, followed by 100% simulated operating-condition testing before shipment.

Technical Specifications

• Model: CP0-10-P-10R
• Series: SUNNY / HYTEK CP0 Series
• Pump Type: Fixed-Displacement Internal Gear Pump
• Configuration: CP0
• Control Method: Fixed displacement, mechanical
• Rotation: Right / Clockwise configuration indicated by the R suffix; CP0-20-P-10R public model documentation confirms right-hand rotation when viewed from the shaft end.
• Maximum Pressure: Public CP-series data references pressures up to 35 MPa, but this should not be treated as a confirmed CP0-10-P-10R rating without the corresponding model-specific datasheet.
• Speed Range: Public CP0-20-P-10R data specifies 600–3000 rpm; other CP-series sources show different series-level limits, so CP0-10-P-10R requires configuration-specific verification.
• Exact Displacement: Not stated here because currently available public sources do not provide sufficiently reliable model-specific confirmation.
• Weight: Not stated due to insufficient model-specific source evidence.
• Mounting Dimensions: Must be confirmed from the actual configuration drawing/nameplate.
• CP0 Series Displacement Range: Approximately 5–25 mL/rev at the series level.

Key Technical Advantages

1. Internal Gear Architecture

The CP0 platform uses internal gear meshing to provide smooth hydraulic delivery with low pulsation. Public CP-series documentation specifically highlights low noise and very low flow and pressure pulsation.

2. Axial and Radial Pressure Compensation

The pressure-compensation concept is designed to control internal clearances as operating pressure changes, supporting volumetric performance under demanding hydraulic conditions.

3. Low-Noise Hydraulic Power

High-strength cast-iron construction combined with an internal noise-reduction design is intended to reduce mechanical and hydraulic noise. This is particularly relevant to injection molding and other factory-floor applications where machine noise is an operating concern.

4. Servo-Compatible Fixed-Displacement Design

Because CP0 is a fixed-displacement pump, flow can be controlled indirectly through drive speed. This makes the platform suitable for servo-motor or variable-frequency-drive hydraulic systems where pump speed is adjusted according to machine demand.

5. Compact Hydraulic Power Solution

CP0 is positioned as the compact member of the CP internal gear pump platform, making it appropriate for smaller hydraulic power packs and auxiliary circuits where installation space is limited.

6. Double-Pump Integration

Public CP-series technical information states that the pumps can be combined into double-pump configurations, allowing multiple hydraulic circuits or combined flow requirements to be integrated into a compact power unit.

Application Areas

Typical applications include:

• Plastic injection molding machines
• Servo injection hydraulic systems
• Industrial hydraulic power units
• Metal-cutting machinery
• Shoe manufacturing machinery
• Die-casting machinery
• Compact forming equipment
• Hydraulic auxiliary circuits
• Factory automation equipment
• Hydraulic test systems

Public CP-series materials specifically identify plastics machinery, shoe machinery, die-casting machinery, forklifts and industrial hydraulic systems, with particular suitability for servo variable-frequency-drive energy-saving applications.

Expert Maintenance Tips

1. Prime the Pump Before Startup

Before initial commissioning, ensure the pump and suction line are properly filled with hydraulic oil and that trapped air has been removed. Air inside the pump can cause unstable priming, excessive noise and poor hydraulic performance.

2. Protect the Suction Side

Maintain adequate reservoir level and prevent vortex formation at the suction connection. Excessive suction-line restriction, air leakage or contamination can adversely affect pump filling and service life.

3. Start at Low Speed and Low Load

The public CP installation guidance recommends starting the pump unloaded and at low engine or drive speed, then confirming stable oil delivery before progressively applying machine load.

4. Verify Rotation

The R suffix denotes the right-hand rotation configuration. Always verify motor rotation before commissioning. The CP0-20-P-10R public specification confirms clockwise rotation when viewed from the shaft end.

5. Do Not Mix Series-Level and Model-Level Ratings

This is particularly important for CP0 products. Public sources contain different series-level and model-level figures, including 25 MPa / 4000 rpm for general CP-series descriptions and 35 MPa / 3000 rpm for the specific CP0-20-P-10R listing.

For the CP0-10-P-10R, final procurement should therefore be based on the exact technical document corresponding to the actual pump configuration.

6. Match the Full Configuration for Replacement

For reliable interchangeability, verify:

CP0-10-P-10R + rotation + shaft configuration + mounting flange + port arrangement + actual displacement + pressure rating.

Matching only the CP0-10 designation is not sufficient for a true drop-in replacement.
