BOOSTER Gear pump for polymer processing

Product catalog summary

Overview: The BOOSTER gear pump is designed for polymer processing, specifically to transfer and boost the pressure of medium to high viscosity media such as pre-polymers and polymers (e.g., PET, PBT, PS, ABS). It operates with heat transfer oil or steam for heating and utilizes components from the WITTE building block system.

Technical Features:

Housing: Made from heat-resistant carbon steel or stainless steel, with optional coatings.
Gears: Constructed from tool steel or nitrited steel, with options for special steel and surface coatings. Helical and herringbone gearing are available for low-pulsation conveyance.
Friction Bearings: Available in tool steel, Al-bronze, NiAg, with optional surface coatings.
Shaft Seal: Includes viscoseal and vacuum viscoseal, with a stuffing box option.
Heating Systems: Utilizes heat transfer oil or steam.

Operating Parameters:

Viscosity: Up to 40,000 Pas
Temperature: Up to 350 °C (662 °F)
Suction Pressure: Vacuum up to 120 bar (1,740 psig)
Differential Pressure: Up to 250 bar (3,626 psig)

Application Examples: Suitable for various polymers including PET, PBT, PA, PC, PS, SAN, ABS, HIPS, PP, PE, POM, and biopolymers. Applications include polymer discharge, transfer, metering, granulation, spinnery, and fiber production.

Seals and Applications:

Viscoseal: Standard seal for high viscosities and suction pressures, suitable for high pressures and temperatures.
Stuffing Box: Used as an additional seal, made from expanded pure graphite with structural textile fibers.

Pump Sizes and Capacities: Ranges from size 22/22 (4.7 cm³/rev) to 280/280 (12,000 cm³/rev), with capacities varying based on fluid characteristics and operating conditions.

Global Presence: WITTE PUMPS & TECHNOLOGY operates in Germany, Russia, China, USA, and Malaysia.

The reliable transfer and booster gear pump for polymer processing Gear pumps are used in the polymerization process, to boost the pressure of medium to high viscosity media. They transport pre-polymers and polymers, e.g. PET, PBT, PS, ABS and many more, very gently Heating is either by way of heat transfer oil or steam. The core components like shafts and friction bearings originate from the WITTE building block system. Technical Features Housing: Heat resistant carbon steel, e.g. 1.6582 (4340), stainless steel e.g. 1.4313 (E415) optional: coating Gears: Tool steel, nitrited steel, optional:...

Seals Viscoseal (VS) The viscoseal is the standard seal for WITTE EXTRU and BOOSTER pumps. This is a dynamic seal for high viscosities and suction pressures. It can be provided with heating or cooling. The dynamic seal is suitable for high pressures and temperatures. Its range of use is limited by the suction pressure and the viscosity of the medium being conveyed (at least 50 Pas). The viscosity can be increased by an additional cooling system if necessary. Viscoseal (VS) with stuffing box The stuffing box can be used as an additional seal for the viscoseal. The stuffing box is a simple (static)...
