Replace SQP Series Vane Pump | SQP3, SQP4, SQP42, SQP43 | Low Noise

SQP Series High-Performance Low Noise Single & Double Vane Pumps

Product Overview: The SQP Series is the industry benchmark for “Silent Power” in hydraulic systems, widely utilized in injection molding, die-casting, and precision CNC machinery. Featuring an advanced cartridge-based design, the SQP series delivers stable power output while maintaining exceptionally low decibel levels. This featured range includes high-spec single pumps like SQP3-38-1F-18 and SQP4-50-86D-18, alongside high-capacity double pumps such as SQP42-42-21-VQ-86DC-18 and SQP43-50-25VQ-86DD-18. Utilizing a precision pressure-balanced construction, the SQP series ensures peak performance even at operating pressures up to 17.2 MPa.

Key Technical Advantages:

• Ultra-Low Noise Operation: Utilizing specialized silencing grooves and optimized vane geometry, the operational noise is significantly lower than standard pumps, making it the premier choice for modern eco-friendly factories.

• Rapid Maintenance with Cartridge Kits: The internal components feature a “drop-in” modular design. Maintenance is streamlined—swap the cartridge kit without disconnecting main plumbing to restore 100% factory performance and minimize downtime.

• Flexible Double Pump Integration: Models like SQP42 and SQP43 integrate two independent displacement cartridges within a single housing, allowing one drive shaft to power separate high-pressure and auxiliary circuits, saving space.

• High Responsiveness & Long Life: Built-in automatic clearance compensation minimizes internal leakage. Even under long-cycle, high-frequency operations (such as injection cycles), it maintains superior volumetric efficiency.

• Target Applications: Plastic processing machinery, aluminum die-casting machines, bending machines, heavy-duty machine tools, and automated Hydraulic Power Units (HPU).
