Curve Conditions - Grundfos ALPHA2 L Series Installation And Operating Instructions Manual

The guidelines below apply to the curves on the next pages:
• Test liquid: Airless water.
• The curves apply to a density of ρ = 983.2 kg/m
temperature of +60 °C.
• All curves show average values and should not be used as guarantee
curves. If a specific minimum performance is required, individual
measurements must be made.
• The curves for speeds I, II and III are marked.
• The curves apply to a kinematic viscosity of υ = 0.474 mm
(0.474 cSt).
