Application limits
Data Description
Liquid temperature 40°C (104°F) maximum
If the pump is not equipped with cooling jacket, the pump can be operated at full
load only if at least half the stator housing is submerged.
Warm-liquid version: 90°C (195°F) maximum
At increased temperatures, the pump must be completely submerged when
operating at full load.
Ex-approved pumps: 40°C (104°F) maximum
Liquid density 1100 kg/m³ (9.2 lb per US gal) maximum
pH of the pumped media
(liquid)
5.5–14 for cast iron pumps
3–14 for stainless steel pumps
Depth of immersion 20 m (65 ft) maximum
Other For the specific weight, current, voltage, power ratings, and speed of the pump, see
