TYPES UP & UP-DO

Housing and impeller material: Stainless steel ANSI 316Ti (1.4571)

Elastomers: EPDM, FKM (e.g. Viton®), FEP, FFKM (e.g. Kalrez®)

Mechanical seal materials: SiC (silicon carbide), graphite carbon, PTFE-GF, Al₂O₃-ceramics

Metal parts: Stainless steel ANSI 316Ti (1.4571)

UP SERIES

The UP series is for those applications in which a non-metallic pump cannot be used or is not desired, e.g. for temperatures up to 150°C. The impeller is directly mounted on the motor shaft extension. The pump is sealed with a single mechanical seal that is cooled and lubricated by the fluid.

Advantages:

• Robust housing parts made with high wall thickness
• Compact close-coupled design
• Easy installation
• Suited for high temperatures

Solid particles up to 3 mm in size and 10% volume are allowed. The maximum viscosity is 150 mPas, the maximum allowed temperature is 150°C. All sizes are also available in Atex-certified versions under the name UP-EX for Atex zones 1 and 2.

UP-DO SERIES

The UP-DO series is for those applications where a non-metallic hermetically sealed pump is required for temperatures up to 150°C. A double mechanical seal in back-to-back configuration seals
the pumps and prevents harmful media from entering the atmosphere. The double seal is cooled and lubricated by a barrier fluid, for which a separate seal support system is required. Seals and
elastomers are available in many materials.

Advantages:

• Dry run safe when using a pressurized seal support system
• No evaporation of harmful media into the atmosphere
• Suited for high temperatures
• Meets the requirements of the German TA Luft air pollution control regulation

Solid particles up to 3 mm in size and 10% volume are allowed. The maximum viscosity is 150 mPas, the maximum allowed temperature is 150°C.
