Chemical pumps CHEM CHEM gear pumps for transferring and metering low-to-medium viscous media. The application area ranges from conventional transfer and metering tasks in the chemical and pharmaceutical industries to pumping monomers, oligomers and prepolymers in the production of polymers. Decades of design experience and optimal material selection have optimised these chemical pumps for even the most challenging tasks with impressive reliability and metering accuracy in vacuum as well as high-pressure applications. The CHEM series is also suitable for pumping fats or plant oils, for...

Booster pumps BOOSTER/BOOSTER-AT The reliable booster pump for the polymer processes. BOOSTER gear pumps are used in the polymerisation process, among other things, to increase pressure for medium-to-high viscous media. The hydraulically heated booster pump very gently transfers polymers such as PET, PBT, PS, ABS and many others. Heat transfer oil or steam is used for heating. The core components, such as shafts and friction bearings, come from the WITTE modular system. The pumps from the BOOSTER series are used everywhere where especially high pressure is required for the process. High...

Discharge pumps POLY/POLY-AT Reliable and robust pumps are especially needed in the polymerisation process for emptying reactors and containers. The pumps transfer the melt to downstream process steps. The highly viscous material must be pumped from a reactor that is under vacuum conditions. Discharge pumps in the POLY series are precisely adapted to this task. The customer can choose between a standard design or a custom solution that meets requirements exactly. These pumps achieve the best efficiency thanks to optimised shaft and bearing geometries. Energy consumption is kept low so that...

Metering systems/pumps CHEMICALS Sample structure of a metering system Metering systems In many fields, special processes call for special solutions. WITTE offers its customers custom metering systems in addition to a wide range of standard metering and chemical pumps. These systems are based on chemical pumps. Different measurement and control systems are available depending on requirements. Supply tank: Metering pumps for the production of chemical fibres Container with medium Speed-controlled motor Mass flow meter: Synthetic chemical fibres are becoming increasingly important. They are...

Extrusion pumps EXTRU The extrusion gear pump is used for melt in connection with extruders or mixers. It reduces the intrinsic pulsation and uneven transfer especially from single-screw extruders. The pump builds up the necessary discharge pressure needed for downstream equipment. The pressure build-up is significantly more efficient in the gear pump than in the extruder, which means there is less temperature transfer to the polymer. This relieves the extruder and allows for increased output. The extrusion pump therefore helps transfer the product as gently as possible. The robust design...

Food pumps PURO Technical designs Easy to clean and customisable Stainless-steel gear pump for transferring and metering low-to-medium viscous media. Decades of design experience and optimal material selection have optimised this pump type for even the most challenging tasks with impressive reliability and metering accuracy in vacuum as well as high-pressure applications. Typical application areas for this pump type are situations where conventional food pumps such as rotary piston pumps hit their limits. Pumps of this type can be both heated (hydraulically or electrically) and unheated....

Pump accessories Pressure sensors Frequency converters Pressure sensors provide information about the prevalent pressure ratios in the pump and process. In the event of fluctuations, the pressure can then be regulated accordingly. The coupling ensures the safe transfer of force to the pump. We only use couplings from wellestablished manufacturers. A wide range of versions is used depending on the existing parameters and conditions. We offer various gear versions from renowned manufacturers to match the motors and process in question. All gears are designed and adapted by our engineers in...

Spare parts WITTE offers a comprehensive service, even for gear pumps from other manufacturers Wear and spare parts for pumps from WITTE and other manufacturers Our specialists will also assess your plant on site upon request and analyse the conditions and the process, and identify potential areas of optimisation. Often the plant does not need to be overhauled to increase throughput. We achieve this by installing a specially developed pump that suits the existing installation space. Gear pumps are often exposed to extreme conditions due to the medium, application or environment. Wear parts...
