It can handle water with up to 50% glycol or iso-propanol, operating within 0-100°C temperature range and a maximum pressure difference of 4.2 Bar (40m head). The motor provides 139W max power, with nominal voltage at 28VDC regulated to 24V for motor compatibility. Port sizes are 10mm inlet and 6mm outlet, weighing between 0.8-1 kg.
