Applications: The RCDL / RCDLF is a versatile product that delivers a wide range of media from tap water to industrial liquids, adapts to different temperature, flow and pressure ranges, CDL for non-aggressive liquids, CDLF for mild corrosion Sexual fluid. ★ water supply: water filtration and transportation, water district partition, in charge supercharged, high-rise building pressurized. ★ industrial booster: process water systems, cleaning systems, high pressure washing system, fire fighting system. ★ industrial liquid transport: cooling and air conditioning systems, boiler feed water and condensing systems, machine tools, acid and alkali. ★ water treatment: ultrafiltration system, reverse osmosis system, distillation system, separator, swimming pool. ★ Irrigation: Farmland irrigation, sprinkler irrigation, drip irrigation. Working conditions: ★ thin, clean, non-flammable explosive and does not contain solid particles or fibers of the liquid. ★ liquid temperature: room temperature type -15 ℃ to +70 ℃ hot water +70 ℃ to 120 ℃ ★ maximum ambient temperature: +40 ℃ ★ altitude: up to 1000m light vertical multistage centrifugal pump Click here to see all news photos Pump: RCDL / RCDLF is a non-self-priming vertical multistage centrifugal pump equipped with a standard motor. The motor shaft is connected with the pump shaft through a pump head coupling. The pull rod bolt fixes the pressure cylinder and the overcurrent unit to the pump head and the water inlet and outlet sections Between the pump inlet and outlet in the same line. The pump can be configured according to the needs of intelligent protection device, the pump dry, lack of phase, overload and other effective protection. Motor: ★ motor is fully enclosed, air-cooled two-pole standard motor. ★ Protection class: IP55 ★ Insulation class: F ★ Standard voltage, 50Hz: 1X220-230 / 240V, 3X200-220 / 346-380V, 3X220-240 / 380-415V, 3X380-415V Minimum inlet pressure NPSH: If the pump is not The pressure is lower than the vapor pressure of the liquid being transported, cavitation may occur. To avoid cavitation, ensure that there is a minimum pressure on the inlet side of the pump. The maximum suction H [m] can be calculated as follows: H = Pb × 10.2-NPSH-Hf- Hv-Hs where Pb = barometric pressure [bar] (barometric pressure settable to 1 bar) and Pb is system pressure [bar] in a closed system NPSH = net positive tip [m] Curve on the maximum possible flow of the pump to read). Hf = Line loss at inlet [m]. Hv = steam pressure [m]. Hs = safety margin = minimum 0.5m head. If the calculated H is positive, the pump can be operated at maximum suction. If the calculated H is negative, there must be a minimum inlet pressure H head. Parallel operation: Multiple pumps in parallel to replace a large pump may be more advantages ★ In the variable flow system, to adapt to the system required operating point. ★ increase the possibility of water supply, because the pump failure, only affect the system part of the flow.
[Easy to Install]: Just press the heavy-duty stakes into the ground, push the button once in the back and it start working forever.No messy wiring or electricity bills needed. Of course you would have to place these solar ground lights where it gets maximum exposure to sunlight.
[Energy Saving]: Switch it on and it lights up in low light, in the day it automatically turns off whilst the solar panel absorbs the suns energy and charges up its batteries.No longer have to pay for electricity bills or replacing batteries.
[Superior Performance]: This outdoor Solar Light adopt 2020 newly 150mAh solar panel with built-in 800mAh NI-MH battery, each solar lights can light up for up to 8-12 hours after 6-8h full charge.
[Advanced Design]: Equipped with 12 led instead of 8 led to provide brighter light. Full PC lampshade increase irradiation area.High strength ABS Withstand 200KG, don't need to worry about automobile and kids stepping on.
[IP68 Waterproof]:Our disk lights adopt IP68 dust prevention water proofing designs,even the switch is covered with moisture-proof silicone. Zero problems for a raining day.[Easy to Install]: Just press the heavy-duty stakes into the ground, push the button once in the back and it start working forever.No messy wiring or electricity bills needed. Of course you would have to place these solar ground lights where it gets maximum exposure to sunlight.
