DC pumpsecocirc ®ApplicationsEcocirc pumps (basic, vario and strong) can be used in a widevariety of DC applications where a highly efficient circulationpump is required. Ecocirc pumps are very small, highly efficientand very quiet. The shaftless spherical motor design provides fora long life, maintenance-free pump. Ecocirc pumps are used in awide variety of applications such as medical devices, electronicscooling, chillers, laser cooling, RV hot water systems, batterycooling, and fuel cells.DesignInvented by Laing, the principle of the spherical motor isfundamentally different from conventional canned motor pumps.The single moving part in a spherical motor is a hemisphericalrotor/impeller unit. The rotor/impellor rides on an ultra-hard,wear-resistant ceramic sphere. There are no conventional shaftbearings or seals. This eliminates the possibility of bearing-playwhich is commonly associated with increased noise and the seallessdesign eliminates a potential leak path. These pumps areparticularly robust and provide an exceptionally long service lifein excess of 50,000 hours. Through microprocessor technology,the Ecocirc pump converts the DC input into 3 phase AC outputat the precise frequency and voltage for optimum efficiency. Theself-realigning bearing is lubricated and cooled by the fluid media.Maintenance is not necessary under normal conditions. Evenafter lengthy shutdown periods a reliable start-up is virtuallyguaranteed. Parts exposed to the fluid are completely corrosionresistant even with aggressive fluids.Speed controllerThe integrated speed controller provides a wide range of controland can be easily adjusted by turning a dial in the pump end.It can be adjusted to vary the hydraulic performance and/orthe electrical power consumption. Regardless of the setting,the pump always starts with maximum torque. This ensures areliable start even at the lowest speed. The pump output doesnot vary according to the input voltage. The current draw isaltered as the input voltage changes. This is advantageous inapplications where a defined pump performance is required,despite a varying voltage supply.Integrated over-temperature protectionThe pump has an integrated over-temperature safety device thatshuts the pumps electronics off when reaching the temperaturelimit of +203° F, as a complete shutdown of the pump may resultin adverse effects on a circulating system. Prior to this, theelectronics will reduce the pump speed in order to compensatefor heat gain. However, if the temperature continues to rise(i.e. the fluid media is too hot), the pump will eventually turn offcompletely. After cooling, the pump will restart automatically.Technical dataMotor designVoltagePower consumptionCurrent drawAcceptable mediaInsulation classMax. system pressureElectronically commutatedspherical motor with permanentmagnet rotor/impeller8 - 25 Voltsee pump curvesD5basic and vario: 0.25 – 1.46 AD5strong: 0.13 - 2.1 Adomestic hot water,water/glycol mixtures,other media on request*.IP 42 / Class F150 PSI - 1.0 MPa (10 bar) forpumps with brass housings50 PSI - 0.35 MPa (3.5 bar)for pumps with plastic housingMax. system temperature-10° F to +203° F (-10 to + 95°C) for pumps with brass housing(non-freezing)+32° F to +140°f (+/- 0 to + 60°C) for pumps with plastic housing(non-freezing)Weight1.54 LBS.
