>>> Product Overview
QDL/QDLF is a kind of multifunctional products. 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 is applicable to conveying non-corrosive liquid, while QDLF is suitable for slightly corrosive liquid.
>>> Application
* Water supply: water filter and transport in waterworks, boosting of main pipeline, boosting in high-rise buildings.
* Industrial boosting: process flow water system, fire fighting 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 (RO) system, distillation system, separator, swimming pool.
* Irrigation: farmland irrigation, spray irrigation, dripping irrigation.
