WITTE has specialized in the manufacturing of precision gear pumps for more than 30 years. Our pumps guarantee efficient process design through the best efficiency, highest precision and optimized energy requirements. We are certified according to DIN ISO 9001 and manufacture every pump according to the highest quality criteria. We have an excellent network of suppliers and can rely on a broad portfolio of different materials.
WITTE pumps are well suited for use in the chemical and plastics industry. Especially for polymer production, we offer a broad portfolio to cover the entire process chain. The product range consists of the small dosing pump for additives with 0.23 ccm/rev up to the polymer discharge pump with 24 l/rev various solutions for different requirements. For our customers we offer not only standard solutions, but also exclusive customer-specific solutions.
EXTRU Melt pump
Melt pumps were designed to be combined with extruders. As pump installed downstream from extruders, such units reduce the natural pulsation and generate the pressure required for the mould. On option, we equip the series EXTRU of molten mass pumps with our proved herringbone gearing. Demanding molten masses are especially smoothly fed.
BOOSTER High pressure pump
The high-pressure pumps are characterised by their robust design and able building up high pressures with medium and highly viscous media. Owing to the special teeth, the pulsation is reduced to minimum and downstream moulds can be reliably supplied with constant product flow, which provides for constant product quality and guarantees invariable grade.
POLY Discharge pump
Discharge pumps are characterised by an extra large inlet to assure uniform product flow to the gearwheels. The pumps can be used in a broad range of applications and work also under extreme conditions such as vacuum or low NPSH-criteria.
BOOSTER High Pressure Gear Pump
POLY Discharge Gear Pump
POLY high-pressure gear pump for the discharge of medium to high viscosity media from the reactor. The extra large inlet opening guarantees an even flow of product to the gearwheels even under vacuum or extremely low NPSH conditions.
EXTRU Extrusion Melt Pump
The EXTRU is mainly used in conjunction with extruders or kneaders. It reduces the natural pulsation and irregular conveyance, particularly in single-screw extruders, added to which, the build up of pressure in the gear pump is more efficient in comparison to the extruder. Because of this, less energy or heat is transferred into the polymer and the product is conveyed in a gentle manner. The EXTRU melt pump is indispensable for the manufacture of precision films or micro granulate.
