CHL, CHLF
Horizontal multistage centrifugal pumps
The CHL, CHLF series pumps have compact design with stainless steel stamped-welded impeller and diffuser. Pumps are supplied with single-phase or three-phase motors. Single-phase motor is available up to 2.2kW.
• Power: 0.55 ~ 7.5 kW
• Head: 6 ~ 88 m
• Flow range: 0.5 ~ 32 m³/h
• Temperature of pumped liquid: -15 ~ 70°C
Applications
The CHL, CHLF series pump are mainly used in industrial field:
• Water supply
• Air conditioning systems
• Cooling, circulation and water heating systems
• Water purification systems
• Filtration, water treatment
• Irrigation systems
• Sanitary equipment
• Pressure boosting units
Features and advantages
Pump units of the CHL, CHLF series consist of a flow part and an electric motor with a base. The impellers are made by stamping and welding from sheet stainless steel and are mounted on an extended electric motor shaft in a cantilever manner. The discharge branch is radial, the suction branch is axial. A mechanical seal is used to seal the flow part. The pump body has an opening for draining the working fluid, if necessary. There is also a separate opening in the body for filling the flow part at the moment of start-up to ensure lubrication of the working surfaces of the mechanical seal.
Working conditions
The pumps are designed for pumping clean, non-explosive, low-viscosity liquids that do not contain abrasive, solid, or fibrous inclusions (clean water, mineral water, edible vegetable oil, chemically moderately aggressive liquids, etc.). The liquid pumped by the pump should not be aggressive to stainless steel, which is determined by several factors, the main ones being chlorine content, pH, temperature, type of solvent, and content of petroleum products.
Temperature of pumped liquid:
• Standard version: -15 ~ 70°C
• High-temperature version: -15 ~ 110°C
• Ambient temperature: not more than 40°C
• Altitude above sea level: not more than 1000 m
• Maximum allowable pressure in the pump body: 1.0Mpa (10bar)
Electric motor
The CHL, CHLF series pumps are driven by a TEFC (totally enclosed fan cooled) type asynchronous electric motor.
• Protection class: IP55
• Insulation class: F
• Standard voltage 60Hz: 1x220-240V/3x220-240V/380-415V
