Type key

Technical data

• Permissible temperature range of the fluid -20 °C to +120 °C or -20 °C to +140 °C (depending on the pump type)

• Ambient temperature: 0 °C to +50 °C (1~)
• Mechanical seal for water pumping up to Tmax = +120 °C or +140 °C (depending on the pump type). A glycol admixture of 20% to 40% by volume is permitted up to T ≤ +40 °C.
