QDLF 2

Brand: SHIMGE
Brand: China

QDLF serial light-duty stainless steel vertical multi-stage centrifugal pumps are non-priming vertical multi-stage centrifugal ones made by absorbability of world’s advanced technology and design, with standard vertical motors and quickly equipped mechanical seals, it is convenient for components replacement. They can be applied to slightly corrosive medium due to the flow passage parts made of stainless steel (304) and are substitutes for CR, CRN of the same kind used in abroad, warmly welcomed by users because of their high efficiency, low energy consumption, reliable quality and wide applications.

Feature:
1. Tremendously improve performance and enhance product life due to adoption of excellent water power model and advanced making technics.
2.Enhance operating reliability and conveying medium temperature because of the use of horniness alloy and fluorin rubber mechanical seals.
3. Applied to slightly corrosive medium due to flow passage parts made of stainless steel after process of pressing and welding.
4. Compact structure, small size, light in weight, low noise, remarkable energy saving, easy for overhaul and maintenance.
5. Can be directly installed to main pipe because the inlet and outlet of pump are on the same horizontal line.
6. Easy for users to choose motors because of the adoption of standard motors.
7. To avoid damages from dry rotation, lack of electric phase, over-load etc because aptitude protector can be equipped on users’ request.

Application:
1. Water supply: water filter and transport in waterworks, boosting of main pipeline, boosting in high-rise buildings, and etc.
2. Industrial boosting: process flow water system, cleaning system, high-pressure washing system and fire-fighting system.
3. Industrial liquid conveying: cooling and air-conditioning system, boiler water supply and condensing system, machine tool working purpose, slight acid alkali liquid.
4. Irrigation: farmland irrigation, spray irrigation and dripping irrigation.

Working Condition:
1. Medium temperature: -15oC ~ +120oC
2. Max ambient temperature: +40oC
3. Max ambient pressure: 10bar.
4. Advisable to use motor of higher power in case that the density or viscosity of medium is above that of water.
