Performance Parameters
Maximum Operating Pressure: 300 bar (under continuous operating conditions), with a peak pressure of up to 350 bar.
Viscosity Range: Suitable for media with a viscosity of 10–1500 cSt (such as hot melt adhesives, resins, asphalt, lubricants).
Temperature Range: -30°C to +180°C (upper limit determined by sealing materials).
Rotational Speed Range: 100–1350 rpm (recommended rotational speed of 500–1000 rpm to optimize service life). Applications include polymer extrusion production lines (such as pelletizers and reactor feed systems).
High-temperature asphalt/heavy oil transfer systems.
Metered transfer of high-viscosity resins and plasticizers in chemical processes.
Centralized lubrication systems for large equipment (such as wind turbine gearboxes and rolling mills).
Inapplicable Scenarios:
Media containing solid particles or highly corrosive substances (custom hardening treatment required).
Precision metering applications requiring extremely low pulsation (screw pumps are recommended).
III. Technical Advantages
High-Pressure Durability
Utilizes hardened gears and floating bushing design, which automatically compensates for clearance after wear, maintaining high volumetric efficiency (>90%).
Low-Shear Transfer
Optimized involute gear tooth profiles reduce structural damage to sensitive media (such as hot melt adhesives).
Modular Configuration
Seal Options: Replaceable with high-temperature/corrosion-resistant seals such as V (Viton fluororubber) and G (graphite packing).
Drive End Adaptability: Available with SAE, DIN, or ISO standard flanges (this model features a DIN flange).
