Remedy The pump's power consumption changes as a function of the heating system's requirements.
GRUNDFOS SP-series submersibles are suitable for:
Flow noise is caused by the friction of the medium at bottlenecks in the pipe network, e.g. at the valve openings of thermostat valves. This can be remedied by reducing pump output.
Solid particles in the pumped medium generate friction, which leads to abrasion of the material.
