SOLAR PM2 OEM circulator pump for solar thermal charging station

Overview

Overview

The Grundfos Solar PM2 is energy optimized for small and medium solar thermal charging station in which the demand is mainly on small reduced flow.

Characteristic Features

  • Glandless circulator pumps integrated in products shall have an energy efficiency index (EEI) of not more than 0.23, the benchmark level being 0.20
  • Controlled via a digital low-voltage pulse-width modulation (PWM) signal which means that the speed of rotation depends on the input signal. The speed changes as a function of the input profile.
  • Cataphoretically coated cast iron housing

Benefits

  • Ready for Conversion according to Ecodesign Requirements for August, 2015
  • Fit for cold antifreeze media containing glycol or ethanol
  • Fit for condensing environments: electronics separated from motor, motor protected against condensed water by drain holes and double-coated wiring

SOLAR PM2 (Data booklet)

This circulator pump is designed to be integrated in matched-flow solar thermal energy systems with remote control of the speed, corresponding to low-voltage PWM signal from a solar controller. By controlling the speed of the pump in so-called matched-flow systems, the solar harvesting and the temperature of the system can be optimised. Additionally, the power consumption of the pump will be reduced considerably.
