Typical applications
Ending (T) is a versatile product that can deliver a variety of different media from tap water to industrial liquids, suitable for different temperatures, flow rates and pressure ranges
The terminal DFLT is suitable for non-corrosive liquid, and DFL is suitable for mild corrosive liquid.
Water supply: water plant filtration and transportation, water plant zone water delivery high-rise building pressurization.
Exhaust industrial pressurization: flow water system, cleaning system, high-pressure flushing system, fire control system.
Cooling and air conditioning system, boiler feed water and condensing system, machine tool kit, acid and alkali.
Water treatment: filtration system, reverse osmosis system, distillation system, separator, swimming pool, etc.
Ending irrigation: field irrigation, sprinkler irrigation, drip irrigation, etc.
Performance curve
All curves are based on the measurement values of the motor at a constant speed of 2900rpm or 2950rpm.
Ending ISO9906, appendix A.
Low test using 20 ºC air does not contain water, kinematic viscosity was 1 / s
The use of the piston pump refers to the performance range of the thick line, so as to prevent the flow rate from being too small to overheat or overload of the ambassador motor.
Operating conditions
A liquid that is rarefied, clean, non-flammable and explosive and contains no solid particles or fiber.
Type low liquid temperature: room temperature 15 ºC ~ + 70 ºC hot water operated - 15 ºC ~ + 120 ºC
Low temperature: the highest + 40 ºC
Ending altitude: maximum 1000m
Pump instructions
Low DFL (T) is a standard motor of self-priming vertical multistage centrifugal pump, the motor shaft and pump shaft coupling connected directly, the external pull rod with a nut, fixed between the bracket and in and out of the water flow components, pump out in a straight line at the bottom of the pump
The intelligent protector can be equipped with the pump as required to effectively protect the dry rotation, lack of phase and overload of the pump.
Altitude and ambient temperature
Low when the pump in the environmental temperature is more than 40 ºC or at an altitude of more than 1000 m run, the motor output power P2 can be reduced, so the pump under such circumstances, the motor power to be big
