ALPHA SOLAR N
CIRCULATOR PUMPS
Description
Grundfos ALPHA SOLAR pumps are high-efficiency circulators, designed for thermal solar systems. The pump features three constant-curve modes. The speed can also be controlled by a low-voltage PWM signal from a solar controller to optimise the solar harvesting and temperature of the system.
System pressure
Maximum 1.0 MPa (10 bar)
Minimum inlet pressure 0.05 MPa (0.50 bar) at 95 °C liquid temperature
Maximum inlet pressure 1 MPa (10 bar)
Maximum liquid temperature 2-110 °C at 70 °C
Ambient temperature 2-130 °C at 60 °C
Ambient temperature Enclosure class IPX4D(with drain holes)
Insulation class F (EN 60335-1) TF class TF110 at 70 °C ambient temperature
Motor protection No external protection needed Approval and marking CE Water/propylene glycol mixture Maximum water/propylene glycol mixture is 50 %. Note: The water/propylene glycol mixture reduces the performance due to higher viscosity
