Product details
QDLF pump is a multifunctional product, which is a non self-priming multi-stage centrifugal pump designed for installing standard motors. The motor shaft is directly connected to the pump shaft through a coupling at the pump head, and the pressure resistant cylinder and overcurrent components are fixed between the pump head and the inlet and outlet sections by tension rod bolts. The inlet and outlet ports of the pump are on the same straight line at the bottom of the pump; This pump can be equipped with an intelligent protector as needed to effectively protect against dry running, phase loss, overload, and other issues. QDL can transport various media from tap water to industrial liquids, suitable for different temperature, flow rate, and pressure ranges. QDL is suitable for non corrosive liquids, while QDLF is suitable for mildly corrosive liquids. QDLF pumps are widely used in multiple industries, such as water supply: water plant filtration and transportation, water plant zoning water supply, main pipe pressurization, high-rise building pressurization; Irrigation: farmland irrigation, sprinkler irrigation, drip irrigation; Industrial liquid transportation: cooling and air conditioning systems, boiler feedwater and condensing systems, machine tool matching, acid and alkali; Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator, swimming pool; Industrial pressurization: process water system, cleaning system, high-pressure flushing system, fire protection system, etc.
Operating conditions of QDLF pump:
1. Thin, clean, non flammable and non explosive liquid that does not contain solid particles or fibers.
2. Liquid temperature: Room temperature type -15 ℃ to+70 ℃, hot water type+70 ℃ to+120 ℃
3. Environmental temperature: maximum+40 ℃
4. Altitude: up to 1000m
