QY, QYL
Stainless steel self-suction gas-liquid mixing pumps
The QY, QYL pump is designed for liquids with low viscosity, or liquids containing external particles, and is only used for clean liquids.
• Power: 0.55 ~ 7.5 kW
• Head:10 ~ 70 m
• Flow range: 0.4 ~ 22.4 m³/h
• Temperature of pumped liquid: -15 ~ 105°C
Applications
• Equipment for processing gas-liquid mixtures, for preparing ozonized, for biological treatment.
• Suppy of heat or coolant fortemperature control device.
• Filtration systems: Pumping out volatile liquids (gasoline, petrol, various solvents, etc.) from underground reservoirs and supplying them under high-pressure.
• Aerosol treatment of water, food products, chemical solutions and waste.
• Long-term operation, hydraulic pressure change, high0rise building water supply, high pressure tank water injection, flow heater water supply.
• Pumping foaming liquids, supplying liquids through long horizontal pipelines where air pockets may form.
Features and advantages
The QY, QYL pump consist of two main parts (flow part and electric motor) and are mounted on a common frame base. The shafts are connected using an elastic coupling, which is protected by a protective casing for safety purposes. The bearings are installed in a single pump part housing, which ensures precise centering, the absence of radial vibration, and improves the rigidity of rotating parts. Ball bearings are used as supports.
QY, QYL pumps can suck in water and gas simultaneously, mix them and pump the resulting mixture into the system. The mixing process creates ultra-small air bubbles of 20-30 microns.
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: -15 ~ 105°C
• Maximum ambient temperature: 40°C
• Gas-liquid ration 1:9 (gas consumption 8-10% of liquid consumption)
• Suction port: Horizonal; Discharge port: Vertical
Electric motor
A three-phase asynchronous electric motor is used as a drive for the pumping unit.
• Energy efficiency class: IE2
• Protection class: IP55
• Insulation class: F
• Standard voltage 60Hz: 1x220V/3x380V
