• State-of-the-art pump hydraulics and IE3/IE4 motor technology for reliable and energy saving operation
• Long service life thanks to corrosion-resistant cataphoretic coating of all cast components
• Targeted discharge of condensate when used in air-conditioning systems and chillers
• Easy installation with the possibility of securing the pump feet for maximum stability
• Can be used in main/standby operation or peak-load operation (with an external auxiliary device)

Design

Technical data

• Permitted temperature range of the fluid: -20 °C to +140 °C
• Max. ambient temperature 40 °C
• Mechanical seal for pumping water up to Tmax = +140 °C. Up to T ≤ +40 °C, a glycol admixture of 20 % to 40 % by volume is permissible. An alternative mechanical seal must be provided for water-glycol mixtures with a glycol content of > 40% to max. 50% by volume and a fluid temperature of > +40 °C to max. +120 °C or other fluids that differ from water. When using water-glycol mixtures, the use of an S1 variant with a corresponding mechanical seal is generally recommended.
• Mains connection 3~400 V, 50 Hz (others on request)
• Protection class IP55
• Nominal diameter DN 32 to DN 200
• Standard version for operating pressure: 13 bar (up to +140 °C) / 16 bar (up to +120 °C)
