IGP3-H010-H012-H016 Duplomatic Gear Pump 250bar 10.2cc

Product Overview

The IGP3-H010/H012/H016 and IGP4-H020/H025/H032 are part of the mature “straight-line conjugate” internal gear pump platform. Featuring an innovative straight-line conjugate tooth profile, this design eliminates oil trapping, resulting in extremely low pressure pulsation (approx. ±2%) and superior low-noise performance.

Equipped with both axial and radial pressure compensation, these pumps maintain high efficiency across their entire pressure range. The high-strength cast iron housing and special friction bearings enable reliable operation at a continuous pressure of 250 bar (25 MPa) and peak pressures up to 320 bar (32 MPa).

Manufactured to original specifications, this product ensures 100% drop-in interchangeability. Every unit undergoes rigorous 100% simulated duty-cycle testing.

Brand Disclaimer: This product is a high-quality compatible replacement engineered for full interchangeability. All brand names and model codes are referenced solely to indicate compatibility. This product is manufactured by an independent producer.

Key Technical Advantages

1. Ultra-Low Noise & Pulsation: The straight-line conjugate tooth profile minimizes noise and pressure pulsation. Ideal for noise-sensitive applications like injection molding machines.

2. High Efficiency & Pressure Compensation: Axial and radial pressure compensation ensures high volumetric efficiency, even at low speeds.

3. High Reliability: The cast iron housing and special friction bearings withstand continuous 250 bar and peak 320 bar pressures.

4. Servo Motor Compatibility: Optimized for servo motor applications, providing rapid response to speed changes and excellent pressure-holding at low RPM.

Application Areas

• Plastic Machinery: Injection molding, blow molding, extrusion machines

• Rubber Machinery: Rubber vulcanizing presses

• Machine Tools: Bending machines, shearing machines

• General Industry: Systems requiring low noise, high precision, and high reliability.

Expert Maintenance Tips

1. Fluid Cleanliness: Maintain system cleanliness to ISO 4406 19/17/14 or better. Use a ≤10 μm inlet filter.

2. Inlet Conditions: Ensure suction line is unrestricted. Inlet pressure must not fall below 0.8 bar (absolute) to prevent cavitation.

3. Startup: Fill with oil and bleed air before starting. Never run dry. Jog start under no-load until air is purged.

4. Viscosity: Recommended viscosity is 25–100 cSt. For cold starts, preheat oil or reduce speed if viscosity is too high.
