CDL/CDLF is vertical non-self-priming multistage pump equipped with electric motor. Motor shaft is directly connected to pump shaft with coupling. Rod bolts fix pressure resistant cylinder, water flow parts between pump head and base. Water inlet and outlet keep horizon over base. Smart protector is available for protection from dry run, phase loss, overload.
Pump
Vertical structure, inlet and outlet flanges are on the same centerline, compact structure, low area occupies, easy to install.
Equipped with cartridge mechanical seal, easier to install and maintain while ensure sealing
CDLF models Water flow parts made with stainless steel (CDL models main flow parts made with stainless steel), does not pollute medium, ensure long lifespan and beautiful exterior.
Motor shaft connects with pump shaft with coupling.
Low noise and vibration.
Standard design with good compatibility.
Electric Motor
Structure
Material
Transit medium
Medium Temperature: -15℃~+70℃——Normal
-15℃~+70℃——Hot Water
Transit thin, clean, Non-solid particles contained or non-explosive medium
CDLF-Transit mild corrosive medium
CDL-Transit non-corrosive medium
Application Area
Water supply: transit in water plant, pressure boost in high building.
Industrial fluid transit: air condition system, boiler water supply, lathe complement.
Water Treatment : counter-infiltration and swimming pool water treatment system.
Irrigation: Farm irrigation, spray irrigation, drop irrigation.
Operation Conditions & Range
Max Working Pressure & Max Inlet Vacuum Pressure
Performance Curve Explanation
All curves are based on measured data under …………Speed. η-Q curves are measured from average values of different models. Model installed small impellers has 2% lower efficiency than shown curve of this model has normal curve. P-Q Shaft power curves represents average value of single impeller(When equipped small impeller, Pc represents normal impeller, Px represents small impeller). H-Q single stage lift curve represents average value of single impeller(When equipped small impeller, Hc represents normal impeller, Hx represents small impeller);NPSH-Q represents redundant gas pressure. When model selection, add minimum 0.5 bar for margin of safety.
Curve tolerance satisfy standard GB/T3216-2005, appendix C.
Measurement taken under atmosphere temperature, Non-air contained water.
Please use recommend bold line range on charts in avoid of danger caused by the overflow or insufficient flow.
