Shanghai Zhongdu pump manufacturing co.,ltd is an enterprise integrating the research, development, production, sales and service of pumps. It is professional, dedicated, and concentrated on vertical, horizontal and immersed multi-stage centrifugal pumps, sewage submersible pumps and other products.

Zhongdu vertical multi-stage centrifugal pump CDL(F) is one of our important products. The product has introduced foreign advanced technology, combined with the existing domestic advantages, and adopts standard vertical motor and quick-install mechanical seal.

Our vertical centrifugal pumps have three major product features.

Vertical multi-stage centrifugal pumps can be directly used in water plant divisional water supply, farmland irrigation, aquaculture, chemical and pharmaceutical, etc. The products have been sold for many years and have been widely used in the market and praised by customers.

As the source manufacturer of centrifugal pumps, we provide good service.

Typical application
CDL(F) is a multifunctional product that can transport a 
variety of different media from tap water to industrial 
liquids, suitable for different temperature, flow and 
pressure ranges.
CDL is suitable for non-corrosive liquids, CDL (F) is 
suitable for mildly corrosive liquids.
Water supply: filtration and transmission in water 
plants, water supply in districts in water plants, and 
pressurization in high-rise buildings.
Industrial booster: process water system, cleaning 
system, high pressure flushing system, fire fighting 
system.
Industrial liquid transportation: cooling and air 
conditioning systems, boiler feed water and condensing 
systems, machine tools, acid and alkali.
Water treatment filtration system, reverse osmosis 
system, distillation system, separator, swimming pool, etc.
Irrigation of farmland irrigation, sprinkler irrigation, drip 
irrigation, etc.

Performance Curve
All curves are based on motor measurements at constant 
speed of 2900rpm or 2950rpm.
The curve tolerance conforms to ISO9906, Appendix A.
The test adopts water without air at 20oC, and the kinematic viscosity is 1mm2/s.
The use of the pump refers to the performance range of the 
bold curve,in order to prevent overheating due to too small 
flow and overloading the motor due to excessive flow.

Operating Conditions
Thin, clean, non-flammable and explosive liquid that does not 
contain solid particles or fibers.
Liquid temperature: Normal type -15oC~+70oC
Hot water type -15oC~+120oC
Maximum ambient temperature: +40oC
Maximum altitude: 1000m

Pump description
CDL (F) is a non-self-priming vertical multi-stage centrifugal 
pump equipped with a standard motor. The motor shaft and the 
pump shaft are directly connected with a coupling.Use the nut to 
fix the outer cylinder and the overflow part between the bracket 
and the inlet-and-outlet water bodies.The inlet-and-outlet of the 
pump are on the same line at the bottom of the pump.
The pump can be equipped with an intelligent protector as 
required to effectively protect the pump from dry running, phase 
loss and overload.
