SQP3-32-86-C-1 Tokimec Hydraulic Vane Pump 100 mL/r 17.5 MPa

Product Overview

The SQP3-32-86-C-1 is a high-performance fixed displacement vane pump from the Tokyo Keiki (TOKIMEC) SQP series. Engineered specifically for low-noise applications, this pump features an advanced parent-child vane cartridge design and delivers exceptional performance in plastic machinery, die-casting equipment, machine tools, and construction machinery. As a 100% drop-in replacement, it directly substitutes the Tokimec original pump without any modifications to mounting interfaces or piping.

Key Technical Advantages

1. Ultra-Low Noise Design: Parent-child vane cartridge construction with pulsation attenuation structure significantly reduces pressure ripple, delivering quieter operation with smoother sound quality.

2. 100% Interchangeability: V-series cartridge kit is fully interchangeable with Tokimec original pumps, matching all mounting dimensions, port configurations, and performance curves.

3. High-Durability Construction: Thickened housing design enhances pump strength and vibration resistance while improving noise suppression performance. Precision-machined internal components minimize leakage and heat generation.

4. Versatile Fluid Compatibility: Supports mineral oil, water-glycol (F11 prefix), and phosphate ester fluids (F3 prefix).

Application Areas

• Plastic injection molding machinery

• Die-casting and metal forming equipment

• CNC machine tools and machining centers

• Construction machinery hydraulic systems

• Industrial hydraulic equipment requiring low-noise operation

Expert Maintenance Tips

1. Mounting Coaxiality: Shaft coaxiality error must be < 0.10 mm with maximum angular error < 0.2°. Use flexible coupling; pump shaft must not bear radial or axial loads.

2. Inlet Pressure Requirements: For mineral oil: +35 to -16.7 KPa; for water-glycol and phosphate ester: +35 to -10.1 KPa.

3. Fluid Cleanliness: Install fine filter (recommended 25 μm) with fluid cleanliness maintained within NAS Class 12.

4. Cold Start Caution: When using SAE 10W oil at 860–54 cSt, limit speed and pressure to 50% of rated values until system reaches operating temperature.

II. SQP3-25 Single Vane Pump

Product Overview

The SQP3-25 is a fixed displacement vane pump from the Tokyo Keiki SQP series with displacement code 25. Delivering 25 USgpm at 1200 RPM, this pump is widely used in medium-to-high pressure industrial hydraulic systems. Featuring parent-child vane cartridge construction with 100% interchangeability with Tokimec original pumps, it is an ideal choice for equipment maintenance and system upgrades.

Technical Specifications (Bulleted List)

Key Technical Advantages

1. Superior Volumetric Efficiency: Precision-machined internal components minimize internal leakage, optimizing energy consumption and reducing operating costs.

2. Flexible Circuit Design: Multiple pump combinations with varying displacements enable simpler circuit design compared to single large-displacement pump systems.

3. Cartridge-Style Maintenance: Rotating elements are integrated into the cartridge kit, allowing quick internal parts replacement without removing the pump from the system.

4. Broad Media Compatibility: Supports mineral oil, water-glycol, and phosphate ester fluids.

Application Areas

• Industrial machine tool hydraulic systems

• Plastic processing equipment

• Die-casting machinery

• Metallurgical equipment

• General industrial hydraulic power units

Expert Maintenance Tips

1. Piping Connections: Size piping according to port dimensions; maintain inlet flow velocity at 0.5–1.5 m/s.

2. Safety Valve Setting: Install a safety relief valve in the system; set pressure must not exceed pump maximum operating pressure.

3. Initial Start-up: For first-time operation or restart after extended downtime, install an air bleed valve or slightly loosen outlet connections to purge air; start under no-load with jogging operation.

4. Fluid Viscosity: Recommended anti-wear hydraulic oil with viscosity grade of 32–68 cSt at 40°C.
