BOOSTER

Product catalog summary

Overview: The document provides detailed information about the BOOSTER gear pump designed for polymer processing. It highlights the pump's ability to handle medium to high viscosity media, such as pre-polymers and polymers, with gentle transport and pressure boosting capabilities.

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, and special materials, with optional surface coatings.
Shaft Seal: Includes Viscoseal and vacuum viscoseal, with a stuffing box as an additional seal 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 pre-polymer discharge, polymer discharge, pressure increase, metering, transfer, 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: The document lists various pump sizes from 22/22 to 280/280, with specific displacement volumes and capacities ranging from 3 to 58,000 liters per hour, depending on fluid characteristics and operating conditions.

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

BOOSTER 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. ill. BOOSTER classic Technical Features Housing: Heat resistant carbon steel, e.g. 1.6582 (4340), stainless steel e.g. 1.4313 (E415) optional: coating Gears: Tool steel,...

Seals / Applications 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...
