Product Details

Introduction:

1. QDLF Made in China High Quality Multistage centrifugal pump is a kind of vertical non self-priming multistage centrifugal pump, which is driven by a standard electric motor.

2. It can be used to convey various medium from tap water to industrial liquid at different temperature and with different flow rate and pressure. QDL type is applicable to conveying non-corrosive liquid, while QDLF is suitable for slightly corrosive liquid.

3. Used to clean, non-flammable and non-explosive liquid containing no solid granules and fibers.

Main Application:

Water supply: Water filter and transport in Waterworks, boosting of main pipeline, boosting in high-rise buildings.
Industrial boosting: Process flow water system, cleaning system, high-pressure washing system, firefighting system.
Industrial liquid conveying: Cooling and air-conditioning system, boiler water supply and condensing system, machine-associated purpose, acids and alkali.
Water treatment: Ultrafiltration system, reverse osmosis system, distillation system, separator, swimming pool.
Irrigation: Farmland irrigation, spray irrigation, dripping irrigation.
