Type key

Technical data

• Permitted temperature range of the fluid: -20 °C to +140 °C
• Ambient temperature: -30 °C to +50 °C
• Minimum efficiency index (MEI) ≥ 0.4
• Mechanical seal for pumping water up to Tmax. = +140 °C. A glycol admixture of 20% to 40% by volume is permissible up to T ≤ +40 °C.
