Witte Pumps & Technology GmbH Discharge Gear Pumps Poly-AT

The POLY-AT design offers exceptional flexibility when it comes to installations beneath the polymer melting 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 both a technical and 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. Maximum flexibility SX version: • Flange geometry integrated in the housing • Minimal installation space MX version: • Blind holes in flange • Largest possible cross section • Minimal pressure loss • Ideally suited for highly viscous polymers LX version: • Flange with through holes • Maximum flexibility for the installation • Very low pressure loss
