The Gear Pump belongs to the class of rotating postive displacement pumps and is ideal to transport different media. Gear Pumps can manage low viscosity liquids like alcohols, solvents or liquid gases as well as medium and high viscosity liquids like polymer melts, gumbase or rubber.

The EXTRU series: gear pumps for the extrusion process. The pump is installed after the extruder and reduces the natural pulsation of the extruder. In addition, the pressure build-up is much more efficient. The extruder is relieved by using an extrusion pump and the energy input into the polymer is significantly reduced. The melt pump thus contributes to conveying the product as gently as possible. The EXTRU is indispensable for the production of precision films or micro pellets.

POLY-AT Discharge gear pumps: Increased efficiency for your polymer process

High efficient discharge gear pumps of the POLY-AT design offer exceptional flexibility when it comes to installations under the polymer reactor. Customers can choose from three different flange geometries to ensure they are always benefiting from the best combination of reactors and pump flanges from technical as well as from economical perspective. The new gear geometries facilitate differential pressures of up to 320 bar for selected pump sizes. What’s more, the new design is rounded out with the usual variety of different material combinations. The most common of these combinations has to be a stainless-steel or carbon-steel housing with tool steel or aluminium-bronze friction bearings.

High effiecent high pressure pump for polymer processing

The next evolutionary step for high-pressure pumps in the polymer process. The series is the result of a complete rework of the used core components. The customer benefits from high flexibility of design and standardization. The BOOSTER is available with flange geometries and connections that comply with EN 1092-1 or ANSI B16.5. It goes without saying that the company also offers housing variants for replacing existing pumps and debottlenecking, not to mention solutions for special requirements based on customer requests. By standardising on three gear widths for each centre distance, the distances between the respective pump sizes have been significantly reduced. This means it is now easier than ever to select the best possible – and therefore most cost-effective – pump size for each application.
