Horizontal Steel Centrifugal Pumps

  • UP Series

    Chemically resistant centrifugal pump in stainless steel, of close-coupled design, with single mechanical seal

    The UP series is the counterpart to the U series for applications where the use of a plastic pump is not possible, for example, due to increased temperature requirements up to 150 °C. It is equipped with a single-acting shaft seal (mechanical seal), which is lubricated and cooled by the process fluid. Sliding surfaces and elastomers are available in various materials; the spring is made of Hastelloy® C4.
    Solids with a particle size of up to 3 mm and a concentration of 10 per cent by volume (vol.%) can be pumped. The viscosity can be up to 150 mPas; depending on the version, the maximum fluid temperature is 150 °C. All sizes are also available in ATEX-certified versions under the designation UP-EX for use in ATEX Zones 1 and 2.

    • Robust and durable design made from thick-walled, solid stainless steel components
    • Compact block design
    • Nem installation
    • Suitable for high temperatures

    Chemically resistant centrifugal pump in stainless steel, of close-coupled design, with single mechanical seal

    Features
    • Robust and durable construction made from thick-walled, solid stainless steel components.
    • Also suitable for liquids with a low solids content thanks to the spring-loaded shaft seal.
    • Low-maintenance operation due to high-quality, smooth surfaces.
    • All wetted parts are made of high-quality, corrosion-resistant stainless steel 1.4571 (AISI 316Ti).
    • Supplied as standard with threaded connections in accordance with ISO 228-1; from size 130, it is also available with flange connections as an option.
    Versatile, compact and quiet.
    Approved for use in explosive atmospheres (ATEX Zone 1).
    Corrosion-resistant coating in RAL 1017, saffron yellow. [1, 2]

    Applications
    Pumping of saltwater, weak acids and bases, or other corrosive liquids. Pumping of water- or oil-based emulsions at temperatures up to 150 °C. Use in harsh environments and in applications that require a particularly robust pump. [1]

    For example in the following applications:
    • Pumping of coolants and thermal oils in cooling or temperature control units
    Galvanising and surface treatment
    • Wastewater and freshwater treatment
    Paper industry
    Laboratory and pharmaceutical technology
    Environmental technology, flue gas cleaning and gas scrubbers [1]

  • UP-DO Series

    Stainless steel centrifugal pump, chemical resistant, single-stage, block design, with single or double acting shaft seal

    The UP-DO series is the counterpart to the U series for applications where the use of a plastic pump is not possible, for example, due to increased temperature requirements of up to 150 °C. Under this designation, it is equipped with a double-acting shaft seal (mechanical seal). Sealing faces and elastomers are available in various materials; the spring is made of Hastelloy® C4.
    Solids up to a particle size of 3 mm and 10% by volume can be pumped together with the liquid. Viscosity can be up to 150 mPas; depending on the version, the maximum liquid temperature is 150°C. All sizes are also available in ATEX-certified versions under the designation UP-EX for use in ATEX zones 1 and 2.

    • Dry-run safe when using a pressurised sealing support system (flushing system)
    • No leakage of toxic or environmentally hazardous liquids
    • Suitable for high temperatures
    • Complies with the German Air Pollution Control Ordinance TA Luft

    Stainless steel centrifugal pump, chemical resistant, single-stage, block design, with single or double acting shaft seal

    Features
    • Robust cabinet parts with a large wall thickness.
    • Particularly suitable for liquids with a solid content thanks to the spring-loaded shaft seal.
    Pumping of magnetic particles is possible.
    • Low-maintenance operation due to high-quality, smooth surfaces.
    • All media-contacting parts are manufactured from high-quality, corrosion-resistant stainless steel 1.4571 (AISI 316 Ti).
    Threaded connections in accordance with ISO 228-1 as standard. Also available with flanged connections as an option (from size 130).
    • Universally applicable, quiet and compact block design.
    Approved for use in explosive atmospheres (ATEX Zone 1).
    • Corrosion-resistant motor surface (lacquering).

    Applications
    Pumping of saltwater, weak acids, bases or other corrosive liquids at temperatures up to 150 °C. For use in demanding applications and harsh environments where a robust pump is required.

    For example in the following applications:
    • Circulation of cooling fluids and thermal oils in cooling or heating units
    Galvanising and surface treatment
    • Wastewater and freshwater treatment
    Laboratory equipment and medical technology
    • Environmental technology, emissions control and gas scrubbers
