BENEFITS CONVENIENCE Silent operation. Integrated and automatic motor overload protection. Speed visualisation through the covers window*. No maintenance. Automatic venting of rotor chamber. Twin head pump : standby pump available at all times or possibility of operating the two pumps in parallel for lower purchase and operating costs. EASY SELECTION Large choice of performances ( single head models and 9 twin models). running speeds for every model. Wide applications : air conditioning and heating. Dual voltage motor - V RELIABILITY IP* glandless pump. Corrosion resistance reinforced. * except CXL DESIGN Hydraulic part Pump casing in-line with threaded ports (flanges PN on DXM - and -, DCX - and -). Twin heads models (DXM/DCX) : twin pumps in a single casing, hydraulic separation by double flap valve on discharge end. Flanges models : bosses on rear for wall mounting, flanges fitted with pressure gauge ports. Motor : pole, wet rotor, self lubrificated bearings. Single phase : speeds per manual selector, integrated capacitor.
