CDM, CDMF
Light Vertical Multistage Centrifugal Pumps
The CDM, CDMF pumps are new generation, high efficiency, non-self-priming vertical multistage centrifugal 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, and high reliability.
• Power: 0.37 ~ 110 kW
• Head: 4 ~ 305 m
• Flow range: 0.6 ~ 240 m³/h
• Temperature of pumped liquid: -15 ~ 70°C
Applications
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 temperatures, different rated flow, and different pressure ranges. CDM is suitable for non-corrosive liquids, and CDMF is suitable for light corrosive liquids.
• Water pressure boosting system
• Filtration and pumping of water in water supply systems
• High pressure washers
• Fire fighting installations
• Cooling and air conditioning systems
• Steam boiler feed system and condensate pumping
• Cooling system for metal-cutting machine tools (supply of lubrication and cooling emulsion), etc.
• Water purification: Ultrafiltration sytsem, reverse osmosis units, oil refineries, separators
• Irrigation: Irrigation of agricultural lands, drip irrigation, sprinkler systems
Features and advantages
• The impeller and guide vanes are stamped and welded with stainless steel plates, using internationally advanced automatic robot laser welding equipment.
• Total enclosed fan-cooled motor (TEFC), IE3 standard, highly efficient, low noise, and environmentally friendly
• Fully covered coupling guard, more obvious brand recognition, and effective protection
• Die-casting base, novel, stable, and lightweight
• Cartridge-type seal, able to move and change within minutes
• High efficiency, energy saving, low noise, environmentally friendly, light weighted, easy to use and maintain, with compact structure, beautiful appearance, and high reliability.
Working conditions
Pump units of the CDM/CDMF series are designed for pumping clean, non-explosive liquids that do not contain abrasive, solid or fibrous inclusions. The pumped medium must not be aggressive to the materials of the flow part.
Temperature of pumped medium:
• Standard version: -15 ~ 70°C
• High-temperature version: -15 ~ 120°C
• Ambient temperature: up to 40°C
• Altitude above seal level: up to 1000 meters
Electric motor
The CDM/CDMF series pumps are driven by an asynchronous electric motor of energy efficiency class IE3 of the TEFC type (totally enclosed fan-cooled electric motor.
• Protection class: IP55
• Insulation class: F
• Standard voltage 60Hz: 3x200-230/346-400V; 3x220-225/380-440V; 3x220-277/380-440V
