APPLICATION CDL/CDLF pump are multi-functional products. lt can be used to convey various medium from tap water to industrial liquid at different temperature and with different flow rate and pressure. CDL type is applicable to conveying noncorrosive liquid, while CDLF is suitable for slightly corrosive liquid. Water supply: water filter and transport in waterworks, boosting of main pipeline, boosting in high rise building. Industrial boosting: process flow water system, cleaning system, high pressure washing 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, RO system, distillation system, separator, swimming pool. Irrigation: Farmland irrigation, dripping irrigation. IDENTICATION OF PUMP MODELS CDL F - Number of stages Rated flow m /h (Common type omitted) parts are of stainless steel or Light vertical multistage centrifugal pump OPERATION CONDITIONS Thin,clean,non-flammable and non-explosive liquid containing no solid granules and fibers. Liquid temperature: Normal temperature type:- +7 ot water type:+7 + Ambient temperature:up to+ Altitude:up to m PUMP CDL/CDLF pump are vertical non-self priming multistage centrifugal pump, which is driven by a standard electric motor.the motor output shaft directly connects with the pump shaft through a coupling. The pressure resistant cylinder and flow passage components are fixed between pump head and in-and outlet section with tie-bar bolts. The inlet and outlet are located at the pump bottom at the same plane. This kind of pump can be equipped with an intelligent protector to effectively prevent it from dry-running,out-of-phase and overload.

To avoid cavitations, a minimum pressure at the inlet side of the pump shall be guaranteed. The max. Suction lift in metres head can be calculated as following formula: =Pb.-NPS-f-v-s Pb =Barometric pressure in bar. (Barometric pressure can be set to bar.) In closed system, Pb indicates the system pressure in bar NPS=Net positive suction head in metres head. (It can be read out from the point of possible max flow rate shown on NPS curve) f =Friction loss in suction pipe in metres head at the highest flow the pump will be delivering. v =Vapour pressure in metres head, see fig s =Safety margin= Minimum. metres head If the calculated result is positive, the pump can operate at a suction lift of max. metres head. If the calculated result is negative, an inlet pressure of minimum metres head is required. There must be a pressure equal to the calculated during operation. Check and ensure that the pump is not in cavitations state CDL,CDLF--- [bar] CDL,CDLF--~-- CDL,CDLF CDL,CDLF----- CDL,CDLF--- CDL,CDLF---- CDL,CDLF---- CDL,CDLF CDL,CDLF-- [bar] [bar] [bar] [bar] [bar] The following figure shows the limitation of pressure and temperature which shall be kept within the region as show in the figure Operation in parallel Connection several pumps in parallel running will be much more benefit than running a single pump. Increasing the possibility of water supply when one pump is in failure, only part of the system flow is effected. Two pumps or more can be connected in parallel running if necessary.
