ECM(H)-SERIES Light Horizontal Multi-Stage Pump
Application The ECMF, series are primarily for the industry : Water treatment processes Industrial cleaner and dishwasher Water boosting on process Heating and cooling for industrial process Air-conditioning system Air freshening,heater device(soft water) Water supply and boosting(drinking water,light chlorine water) Fertilization/metering system Many other special using
Applicable medium Thin, clean, non-flammable and non-explosive liquid containing no solid granules and fibers; Mineral water, soft water, pure water, edible vegetable oil and other light chemical mediums. When the density or viscosity of to -be -conveyed liquid is larger than that of water, it is necessary to select a driving motor of high power. Whether a specific liquid is suitable for the pump depends on many factors, among which the most important ones are chlorine content, PH value, temperature, solvent and oil content.
Operation condition Liquid temperature: ambient temperature -15 0C ~ +70 0C, 0 hot water less than 105 C; 0 Max. environmental temperature: + 50 C Max. operating pressure: 10 bar Max. suction pressure is limited by max. Operating pressure
60Hz
Electric Motor 2-pole induction motor; Single-phase: 110~220V/60Hz Three-phase: 220~380V/60Hz Insulation class: B or F Protection: IPX5 Continuous duty Single-phase with input thermal protector
Pump Horizontal multistage non-self-priming centrifugal pump, attached with long shaft electric motor. Compact structure renders small size of pump; axial inlet and radial outlet.
