EXTRU III Extrusion gear pump

EXTRU III Extrusion gear pump

Product catalog summary
Overview: The EXTRU III is a compact and compatible extrusion gear pump designed for efficient polymer conveyance. Its lightweight construction allows for easy installation, saving time and space. It operates under high viscosities, temperatures, and pressures, making it suitable for various industrial applications.
Specifications: The pump can handle viscosities up to 30,000 Pas, temperatures up to 350°C, suction pressures up to 120 bar, and differential pressures up to 250 bar. It features a heat-resistant carbon steel housing, nitrited tool steel gears, and a dynamic shaft seal known as Viscoseal, which can be cooled if necessary.
Technical Features: The EXTRU III offers precise and almost pulsation-free polymer conveyance, compensating for fluctuations from the extruder. It includes friction bearings with special lubrication pockets for reliable long-term operation. Heating is provided electrically via heating cartridges.
Application Examples: Suitable for polymers such as PS, PET, PC, PA, PMMA, HDPE, LDPE, LLDPE, PP, Polysulfone, and PEEK.
Pump Sizes and Capacities: Sizes range from 22/22 (4.7 cm³/rev) to 180/180 (3,200 cm³/rev), with capacities from 3-56 l/h to 1,920-17,000 l/h, depending on the size and fluid characteristics.
Dimensions and Weight: Detailed dimensions and weights are provided for each pump size, with the largest model weighing 1,170 kg.
Performance Graphs: The document includes graphs showing flow rates and pump speed limits for various polymers, indicating optimal operating conditions.
