Product description

Klaus Union DSP-4CL is intended for high-flow and high-differential-pressure transfer of viscous and multiphase fluids. The range is relevant where process reliability, controlled fluid handling and equipment availability are important selection criteria, particularly in chemical, petrochemical, energy and other process-industry installations.

The pump uses double-volute twin-screw design; Plug & Pump cartridge concept; low-pulsation operation; viscosity up to 100,000 cSt. This construction is selected to match the hydraulic duty, process medium, installation arrangement and sealing philosophy while keeping maintenance access and operating stability in focus.

Current Klaus Union data publishes a capacity up to 5,000 m³/h, a delivery capability of 100 bar differential pressure, a temperature range of -120 to +350 °C and a pressure rating up to PN 150. The family is based on API 676; exact limits depend on pump size, material, operating point and selected configuration.

Correct selection can reduce leakage risk, unplanned maintenance and process interruptions over the equipment life cycle. AxFlow can support duty-point review, materials and configuration selection, spare parts and service planning; contact AxFlow to identify the appropriate Klaus Union DSP-4CL configuration and availability.

Klaus Union DSP-4CL is intended for high-flow and high-differential-pressure transfer of viscous and multiphase fluids. Suitability depends on the liquid, duty point, materials and installation conditions. AxFlow can review the application and help select the correct configuration.
Current Klaus Union data publishes up to 5,000 m³/h, 100 bar differential pressure, a temperature range of -120 to +350 °C and pressure rating up to PN 150. These are family-level limits rather than values for every size. Final selection must be checked against the required operating point and selected materials.
Material selection should be based on chemical compatibility, temperature, pressure and solids content where relevant. Klaus Union offers multiple material and construction options across its process-pump portfolio. AxFlow can help match the wetted materials and configuration to the process medium.
Maintenance requirements depend on the selected pump construction and operating conditions. AxFlow can support spare-parts identification, service planning and inspection of installed equipment. Using the correct parts and maintenance intervals helps reduce avoidable downtime.
Provide the required flow, head or differential pressure, liquid properties, temperature and installation conditions. AxFlow can use this information to identify a suitable pump configuration and check availability. Contact AxFlow to request a quote for Klaus Union DSP-4CL.
