Summary
CDM/CDMF pumps are new generation, high efficiency, non-self-priming vertical multistage centrifugal pumps (Abbr. as pumps). It referred European standard, used entirely new industrial design. It is energy saving, low noise, environment friendly, compact design, beautiful shape, light, easy for service, high reliability.
Application CDM/CDMF pumps are designed for a variety of applications from the pumping of potable water to the pumping of industrial liquids. Applied for liquids of different temperature, different rated flow, different pressure range. CDM is suitable for non-corrosive liquid; CDMF is suitable for light corrosive liquid. Boosting: Filtering and transferring water in water factories, delivering water in different zone, pressuring for major pipelines, boosting for high buildings. Pressuring: Water circulating system, washing system, high pressure flushing system, fire-fighting system. HVAC: Air condition system Water treatment: Ultrafiltration system, R/O system, distillation system, separator, swimming pool.
Motor Totally enclosed, fan cooled, 2 pole standard motor IP class: IP55 Insulation class: F Voltage: 50Hz:1×200-230/240V 3×200-220/346-380V 3×220-240/380-415V Working conditions Thin, clean, non-flammable, non-explosive, solid free, fiber free, physically and chemically water-like liquid. Liquid temperature: Normal temperature type: -15ºC to 70ºC Hot water type:-15ºC to 120ºC Ambient temperature: up to +40ºC Altitude: up to 1000m Performance curve Following conditions are suitable for performance curve below. 1. All curves are based on the measured values of 50Hz; constant motor speed 2900rpm or 2950rpm. 2. Curve tolerance in conformity with ISO9906:2012, Grade 3B. 3. Measurement is done with 20ºC air-free water, kinematic viscosity of 1mm2/sec. 4. The operation of pump shall refer to the performance region indicated by the thickened curve to prevent overheating due to too small flow rate or overload of motor due to too large flow rate.
