Tokimec SQP Series Vane Pump | SQP21 SQP31 SQP32 SQP43 | Tokyo Keiki Replacement

LIC Hydraulic’s Tokimec (Tokyo Keiki) SQP Series double vane pumps are the premier choice for low-noise industrial hydraulic applications. Covering configurations from SQP21 to SQP43, including specific models like SQP21-21-11-1CB-18 and SQP32-25-14VQ-86DC-18, these pumps provide two independent oil flows from a single shaft. We guarantee 100% Drop-in Interchangeability with original Tokyo Keiki units. Every SQP pump undergoes 100% performance testing at rated pressures to ensure quiet, vibration-free operation in injection molding and heavy manufacturing environments.

Technical Specifications

• Series ID: SQP (Low-Noise Fixed Displacement Vane Pump)

• Configurations: Double pump setup (e.g., SQP21, SQP32, SQP43).

• Max Operating Pressure: Up to 175 bar (2538 PSI) depending on cartridge size.

• Flow Codes: Wide range of delivery sizes (e.g., 21, 11, 25, 14) to match system requirements.

• Mounting: Standard SAE 2-bolt or 4-bolt flanges.

• Design Number: 18 series (Current industry standard).

Key Technical Advantages

• Ultra-Quiet Operation: The SQP series is legendary for its silent running. By utilizing advanced vane geometry and pressure-pulsation damping, it maintains an exceptionally low decibel profile, even under high-load conditions.

• Modular Cartridge Maintenance: The pump’s internal rotating group is self-contained. This “Cartridge Kit” design allows for field repairs without removing the pump from the machinery, drastically reducing MTTR (Mean Time To Repair).

• Versatile Flow Management: Engineers can mix and match various front and rear cartridge sizes to optimize energy consumption for dual-speed or multi-function circuits.

• Durable Service Life: Hardened cam rings and bifunctional vanes ensure the SQP series withstands the rigor of continuous 24/7 industrial production cycles.

Expert Maintenance Tips

• Alignment is Key: For the SQP series, ensure the shaft coupling is perfectly aligned within 0.05mm. Misalignment is the leading cause of abnormal noise and premature shaft seal failure.

• Inlet Vacuum: Vane pumps are sensitive to suction issues. Ensure the intake line is large and unrestricted; cavitation “screaming” will quickly destroy the cartridge cam ring.

• Oil Cleanliness: Maintain system filtration at ISO 4406 19/17/14 or better. Clean oil prevents the vanes from sticking in the rotor slots, which is essential for consistent pressure buildup.
