Hangzhou EDUR-WITTE products

Stainless steel centrifugal pumps for the use in the food industry, water supply, cooling and refrigeration technology, air-conditioning, filtration, shipbuilding, apparatus engineering, energy technique and general machine engineering. Wide ranges of applications for simple requirements and clean or slightly polluted liquids.

Horizontal centrifugal pumps for the transport of liquid-gas mixtures and for the enrichment of liquids with gases. By multiphase pumps a dispersion with very fine bubbles is being achieved. Therefore the multiphase pumps are also suitable as dynamic mixer. Some main applications are biofuel plants, dissolved air flotation, neutralization, water treatment, bio-reactors, crude oil water separation on oil rigs and on oil fields as well as general process technology.

Liquid gas pumps are required for unloading, fueling, fuel transfer and for filling processes. The demands on pumps are high: high pressure differences, mixture transport, low NPSH values, low level of pulsations transport, low noise emissi- ons and ATEX conformity. The user does expect a reliable transport also of the liquid-gas mixtures, the control of out- gassing and variations of the steam pressure and more and more popular higher pump efficiencies.

Immersed pumps are all-purpose pumps. Immersed pumps are used where due to the lack of space, poor inflow conditions and/or critical liquids to be pumped, dry installed pumps are disallowed. Immersed pumps do have a modular design for different impeller types and pressure ranges. Examples of typical pump applications are pretreatment plants for surface treatment in which hot aggressive liquids are circulated.

Torque-flow pumps in compact bloc-design for the transport of liquids being contaminated with solids or suspensions. Typical liquids to be pumped by torque flow pumps are waste water, cooling agents contaminated with metal chips, abrasive oils and lyes, lime milk and also products that have to be transported with care. Main application of the pumps  are in sewage water plants, treatment systems, recycling processes, washing plants filters, environmental and operation technique. All-purpose pump design insensitive to cavitation conditions.

Stainless vertical pumps for multipurpose usage. Vertical multistage high pressure pumps in compact design for the usage in booster systems, general process technology, water supply, cooling technology, air-conditioning, apparatus engineering, energy technique, plastics processing, filtration, shipbuilding, and general machine engineering. The vertical pump does offer a wide range of applications for clean or slightly polluted liquids.

EDUR single stage centrifugal pumps are a well-established pump type for economical, reliable and long-lasting operation. All-purpose single-stage circulation pumps in compact design for the use in water supply, cooling and refrigeration technology, air-conditioning, filtration, shipbuilding, apparatus engineering, energy technique, plastics processing and general machine engineering. Wide range of designs with various types and material modifications for clean or slightly polluted liquids. Well-established pump type for economical, reliable and long-lasting operation.

All-purpose single-stage circulation pumps in inline design for the use in water supply, house and building technique, shipbuilding, cooling technology, machine and apparatus engineering. Space-saving alternative to standard bloc-pumps. For clean or slightly polluted liquids.

Multistage horizontal and vertical high pressure pumps in segmental type design with many variants for clean and slightly polluted liquids. Main applications of the multistage pumps are booster systems, irrigation systems, boiler feed and condensate systems, washing plants, filter technique, water treatment and hardening systems. By means of auxiliary NPSH- stages NPSH-values up to 0,5 m are being achieved.
