TOKIMEC SQP Series Vane Pump

The TOKIMEC (Tokyo Keiki) SQP Series is a premier lineup of fixed-displacement industrial intra-vane pumps engineered specifically for high-pressure, low-noise operations in open-circuit hydraulic systems. Renowned across the global manufacturing sector for its exceptionally quiet operational profile and rugged durability, the SQP series is available in four basic frame sizes (SQP1 through SQP4) and can be combined into multi-stage double or triple pump configurations to handle diverse volumetric requirements.

At the core of the SQP series’ success is its pressure-balanced intra-vane cartridge design. By introducing system pressure directly beneath the secondary inner vane, the pump dynamically balances the tracking forces against the cam ring. This minimizes structural friction, eliminates uneven wear, and ensures high volumetric efficiency even when operating at maximum continuous pressures and elevated fluid temperatures.

Core Technical Features & Advantages

• Acoustically Optimized Cam Profiles: Precision-machined internal cam ring geometries control fluid acceleration and deceleration pathways, virtually eliminating the high-frequency fluid pulsations common in standard vane pumps.

• Flexible Geometric Displacements: Wide range of delivery capacities allows system designers to precisely match circuit demands, minimizing energy waste and restricting systemic heat buildup.

• Robust Cast Iron Housing: Built from high-tensile, vibration-absorbing cast iron to prevent structural distortion under heavy cyclic mechanical loading.

• Simplified Field Overhauls: Because the entire pumping mechanism is self-contained within a removable inner cartridge, maintenance teams can fully overhaul the pump in minutes, slashing machine downtime.

• Broad Hydraulic Media Adaptability: High-grade elastomer seals and specialized surface treatments allow the SQP series to operate reliably with standard petroleum-based mineral oils, water-glycols, and synthetic fire-resistant fluids.

Primary Applications

The TOKIMEC SQP vane pump platform is a reliable industrial workhorse heavily utilized across automated, high-duty manufacturing environments:

• Plastic processing, thermoforming networks, and high-output injection molding machinery

• Metal stamping, sheet-metal shearing, die-casting machinery, and industrial automated bending presses

• Heavy-duty industrial Hydraulic Power Units (HPUs) and centralized multi-valve lubrication blocks

• Automated material handling conveyor loops, robotic loading docks, and high-capacity lift elevators

• Primary marine steering gear systems, deck machinery winches, and industrial assembly lines
