Stübbe is a German manufacturer with over 60 years of experience in the production of pumps, armatures and systems from technical polymers, meant to be used for aggressive chemical fluids. The company's solutions are well-established in industrial sectors such as chemical processing, electroplating, wastewater treatment and environmental protection technologies, which require high reliability and durability of materials when operating in harsh operating conditions. Their Classic pumps series are intended for industrial applications, with a focus on chemical substances and aggressive liquids without hard particles. "The pumps in this selection have a housing made of technical polymer - most often polypropylene (PP) or polyvinylidene fluoride (PVDF), which makes them resistant to corrosion and chemical reactions," BalkanEngineer.com was informed by Indumatic, proven engineering and trade firm and provider of Stübbe products.

Centrifugal pumps Classic by Stübbe are suitable for work with aggressive substances without hard particles. They include several basic designs developed for reliable operation with chemically aggressive environments:

Horizontal centrifugal pumps with volute casing (SHB series) are equipped with a mechanical seal and a casing made of PP (polypropylene) or polyvinylidene fluoride (PVDF). They are characterized by a flow rate of up to 130 m³/h, a head of up to about 42 m and are driven by motors with a power of up to 11 kW;
Horizontal centrifugal pumps with magnetic coupling (SHM series) are designed with a hermetically sealed construction without mechanical seal, which completely eliminates the risk of leakage. They are optimized for the safe transfer of toxic, corrosive or sensitive chemical fluids;
Vertical submersible pumps (ETLB series) are block-type pumps, suitable for use in galvanic lines, chemical baths and applications where horizontal construction is difficult to implement. The vertical design allows continuous operation in aggressive environments and facilitates drainage and circulation of chemical solutions.
