Tokimec SQP43 SQP32 Series Double Vane Pump | LIC Hydraulic

The F11-SQP / SQP series (comprising high-volume dual-circuit industrial frame sizes including SQP43 and SQP32 double pumps, specifically detailed by the high-order technological execution codes F11-SQP43-60-38-86DD-18-S147B and F11-SQP32-25-14-86DC-18) manufactured by LIC Hydraulic are premium, fixed-displacement low-noise intra-vane double hydraulic pumps. They are engineered as core fluid power components for modern plastic injection molding machinery, heavy-duty die casting installations, industrial metal scrap compactors, and automated factory HPUs. Conforming exactly to standard rectangular mounting pilots, straight parallel keyed drive shafts, multi-directional SAE split-flange connection interfaces, and interchangeable internal cartridge segments, this entire product line provides 100% drop-in interchangeability with original Tokimec (now Tokyo Keiki) SQP series double vane pumps.

In high-intensity industrial plant operations, standard vane pumps subjected to sustained heavy cyclic pressures frequently experience localized overheating at the vane tips and stator cam ring interfaces, causing severe volumetric drop and piercing airborne noise. LIC resolves these chronic operational flaws by mastering the intra-vane engineering matrix and pressure-balanced dual-chamber geometry. By routing minor pilot line pressure to the micro-chambers between the main vane and intra-vane, the tip-to-ring contact force self-regulates in direct proportion to system load variations. This setup secures an extended service life and an exceptionally low operational noise profile. The “F11” prefix designates an elite upgrade to premium Fluorocarbon (FKM/Viton) seal configurations, offering chemical and thermal stability when operating with synthetic fire-resistant fluids, water glycols, or high-temperature petroleum-based oils. Every double pump undergoes 100% full-load factory testing that challenges both the shaft-end and cover-end circuits under independent peak load thresholds prior to shipping, presenting global B2B system builders with a robust option for heavy industrial manufacturing and aftermarket replacement parts.

Key Technical Advantages

• Pressure-Balanced Hydrostatic Intra-Vane Structural Matrix: The internal pumping core utilizes dual-chamber tracking where the main vane accommodates an independent intra-vane slot. System line pressure is directed underneath the tracking set, ensuring the vanes trace the elliptical cam ring curve with optimized sealing force. This configuration minimizes excessive local friction, providing stable volumetric efficiency exceeding 95% over thousands of operating hours.

• Micro-Honed Side Valve Plates with V-Groove Pressure Dampening: The side wear plates feature precision-machined, micro-tapered V-grooves that facilitate a smooth, gradual pressure equalization as the tracking fluid transition from the suction zone to the high-pressure discharge sector. This layout dampens internal flow pulsations by up to 80%, reducing fluid-borne harmonics and stabilizing downstream control elements.

• Independent Drop-In Cartridge Kit Architecture for Rapid Service: Both the primary and secondary pumping groups within the SQP43 and SQP32 structures are designed as independent, self-contained drop-in cartridge assemblies (including cam ring, rotor, vanes, and side plates). During field overhauls, service technicians can replace the entire wear module within 15 minutes by removing the rear cover bolts without disturbing the main system piping.

• Dual Discharge Flow Efficiency Layout: Utilizing a centralized common intake suction port split internally into separate pumping paths, the double pump architecture enables classic “hi-lo” energy-saving system circuits. High-volume, low-pressure flow can combine with low-volume, high-pressure flow for rapid actuator travel, switching to single high-pressure output during heavy clamping cycles to minimize system heat generation.

Application Areas

The SQP43 and SQP32 series heavy-duty low-noise double vane pumps are standard components in industrial machine tool networks and automated factory manufacturing cells where quiet operation is essential:

• Automated Plastic Injection Molding & Specialized Rubber Compression Presses: Serving as the main dual-circuit power hub to manage fast mold movement cycles and sustained low-power holding phases.

• Heavy Die Casting Machinery & Metal Scrap Balers: Supplying stable, high-volume flow to high-speed auxiliary cylinder rams and primary intensification circuits.

• CNC Precision Machine Tools, Shearing Machinery, & Automated Shoe Assembly Plants: The low vibration and low noise levels of this pump line make it highly suitable for modern, climate-controlled machining centers with strict decibel limits.

• Primary Metallurgy, Continuous Caster Controls, & Power Station Actuators: Utilizing the upgraded “F11” Viton seal framework to deliver reliable fluid power using water glycol or synthetic fire-resistant fluids near high-temperature casting zones.

Expert Maintenance Tips

• Pre-Priming Both Pumping Cavities with Clean Oil is Mandatory Prior to Starting: Vane pumps rely entirely on centrifugal force generated during initial shaft rotation to extend the vanes out of the rotor slots and seal against the cam ring. If the cartridge modules are dry upon startup, running at 1000 rpm for even 3 seconds will cause immediate galling along the cam ring tracking surface and score the vane tips. Fill the pump housing with clean, filtered system oil through the highest port connection before starting the motor.

• Enforce a Hard Minimum Startup Speed of 600 RPM: Because vane extension depends on centrifugal rotation, if the pump is connected to a variable-frequency servo drive set below 600 rpm during startup, the vanes will fail to extend, preventing self-priming and causing rapid frictional heat generation. Set the initial priming speed between 800 and 1200 rpm for at least 30 seconds until pressure stabilizes before adjusting across the full speed range.

• Avoid Over-Filtering the Suction Line or Restricting Intake Piping to Prevent Cavitation: Vane pumps are sensitive to low inlet pressures. Using an intake suction strainer finer than 100-mesh or incorporating excessive elbows in the suction line can generate excessive vacuum at the rotor inlet. The resulting bubble implosions (cavitation) will erode the case-hardened interior layer of the cam ring. Maintain inlet vacuum above -0.2 bar and replace system filters every six months.
