SQP3 Series Vane Pump for Injection Molding | SQP3-30, SQP3-35, SQP3-38 | Low Noise

SQP3 Series High-Performance Low Noise Vane Pumps for Injection Molding

Product Overview: The SQP3 Series fixed displacement vane pump is the definitive “Silent Power Heart” for injection molding and die-casting hydraulic systems globally. Engineered specifically for heavy-duty industrial environments, the SQP3 utilizes an advanced pressure-balanced construction to ensure long-term stability under continuous high-pressure cycles. This featured range includes the complete displacement spectrum: SQP3-21, 25, 30, 32, 35, and 38. Available with multiple port orientations (e.g., 1A, 1B, 1C, 1D), the SQP3 series is the premier choice for OEM replacements, enhancing machine response while significantly reducing workshop noise levels.

Key Technical Advantages:

• Ultimate Silent Operation: Featuring a unique silencing groove design, the SQP3 drastically reduces hydraulic pulsation and mechanical vibration. Even at a rated pressure of 17.2 MPa, decibel levels remain significantly lower than competing models.

• Rapid Maintenance with Cartridge Kits: The internal core adopts a “drop-in” modular cartridge design. Maintenance can be completed in minutes by swapping the cartridge without disconnecting main plumbing, drastically reducing machine downtime.

• High Volumetric Efficiency: Built-in automatic clearance compensation minimizes internal leakage. Even under high-temperature and long-cycle operation, it maintains stable flow output, ensuring the repeat accuracy of injection molding processes.

• Flexible Porting Configurations: Offers various orientations such as 1C (Standard 180°) and 1A (90° CW) to fit the installation space of different machine brands perfectly.

• Target Applications: Vertical/Horizontal injection molding machines, aluminum die-casting machines, hydraulic balers, footwear machinery, and automated Hydraulic Power Units (HPU).
