ALM and ALP by DAB are in-line pumps designed for conditioning, heating, water recirculation in the presence of solar thermal panels (solar collectors) and for the circulation of drinkable hot water in residential building service or commercial building service. The ALM 200 and ALP 800 versions have a bronze pump body and motor support, while the ALM 500 and ALP 2000 versions have a cast iron pump body. ALM pumps have a 4-pole motor, ALP pumps have a 2-pole motor. The motor is air-cooled in all models. All pumps have the ACS certificate for drinkable water. The silicon carbide mechanical seal means that the pump can handle glycol percentages up to 50%.
