Product Description
Model Description
Product Overview
The CHDF stainless steel sectional horizontal multistage pump is equipped with a horizontal extended-shaft motor, featuring axial suction and radial discharge. All wetted parts are made of high-quality stainless-steel plates through stamping and welding, allowing the pump to handle mildly corrosive media. With an excellent hydraulic model and advanced manufacturing technology, the pump offers a wide application range, high efficiency, energy saving, and reliable performance.
Applications
The CHDF stainless steel sectional horizontal multistage pump is suitable for industrial and domestic water supply.
● Air-conditioning systems, fertilization systems, dosing systems, cooling systems
● Environmental applications, industrial cleaning, water supply or pressure-boosting systems
● Water treatment (purification), domestic water supply, aquaculture
● Many other specific and dedicated applications
Operating Conditions
● Liquid temperature:
• Normal temperature type: –15°C to +70°C
• Hot-water type: +70°C to +110°C
● Ambient temperature: up to +40°C, operating pressure: 10 bar
● Maximum inlet pressure is limited by the operating pressure
● Applicable media:
• Thin, clean, non-flammable, non-explosive liquids free of solid particles or fibers
• Suitable for mineral water, softened water, purified water, light oils, and other light chemical media
● If the liquid density or viscosity is higher than that of water, a higher-power motor must be selected if necessary.
● The suitability of the pump for a specific liquid depends on various factors, including chlorine content, pH value, temperature, and the presence of solvents or oils.
