Product Description:

1. Description
CDLK/CDLKF is non-self priming multi-stage centrifugal pump installed with standard motor.The motor shaft is directly connected with the pump shaft through
coupling.According to the requirement,the pump can be equipped with intelligent protector,which effectively protects pump from dry rotation,phase lack,overload etc.In order to meet the requirement of installation depth of the water tank or vessel,it is possible to install cavity body for changing length of the pump.Length for different number of stages is shown in the dimensions & weight table and the table of products supplying scope.

5. FAQ

1>.  Can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

2>.  Are your pumps cheaper than those of your competitors?

CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

3>.  How long is your warranty?

Unless otherwise expressly authorized in writing, by specifying a longer period or different conditions, CNBM states that, for a period of twelve (12) months from delivery date, all Products supplied are free from defects in materials and workmanship, and conform to the applicable specifications. Either the delivery documentation or the invoice must be provided to prove delivery date. In absence of such documents, the production date appearing on the product label may suffice.

4>Can your pumps mount Eff.1 motors

Currently, only on request though this will shortly be a CNBM standard.

5>Are your pumps protected against dry running?

No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

6>How can I get trained on CNBM products?

Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

Q:Suction stroke and lift of water pump
The absorption process is also called the "largest self-priming height" (also can be understood as "the degree of self suction). Micro pumps do not add water at the circumstances, can automatically water suction pump up the maximum height (the vertical distance from the pump to be pumped from the mouth of pumping liquid).Generally lower than the water pump positioned equal when there is self-priming pump required capacity. For example, outdoor tourism, need to extract the water in the river, with the best micro pump self-priming ability (impossible to people ran to the river water inlet pipe with water. It) or pumping the liquid corrosion, easy to add water and so on occasions.
Q:What are the characteristics of a pipe shield pump?
Four, high melting point in the pump hydraulic side and the motor side with a jacket, the jacket can be steam or a certain temperature of liquid to prevent high melting liquid crystallization. The outer circulation pipe of the pump should also be insulated (heating) jacket. Five, high pressure shielding pump shell is a high pressure container, so that the pump can withstand high system pressure. In order to support the shield under internal high pressure, the stator coil itself can be used to bear the pressure. Can also be made in high temperature and high pressure under the operation of the canned pump. Six, since the suction port of the pump impeller center is much higher than that in stopping the pump, when inhaled NO liquid in the tube, the impeller and the increase of the pump chamber is filled with liquid, and then start without irrigation, the pump can work. Self-priming pumps are especially suited for extracting liquids from underground containers. In addition, according to different methods can be divided into liquid type, mud type, high pressure pipeline type, as well as for ships, nuclear power plants and absorption refrigeration devices for various types of canned pumps. Can also be divided into vertical, horizontal, online and single-stage, multi-level and other different types.
Q:What are the parts of a pump? How do you classify it?I just want to know
The liquid ring pump: pumping air, the working medium is generally at room temperature water gas lift pump: simple structure of submersible sewage pump: a form of basic principle, performance parameters of centrifugal pump, with it the same. Underwater installation, sound, water cooling condition, screw pump: spiral lower invasion water medium variety formThere are too many kinds of pumps, such as submersible pumps for wells, centrifugal feed pumps, sewage pumps, etc. the submersible pumps are wet, oil immersed, etc.The water pump for automobiles is divided into oil lubrication and grease lubrication,
Q:How is the pump level of submersible sewage pump determined?
Below the top elevation of the sump, 200 is the warning water levelBut note: 1, the effective volume of the sump meets the requirements. 2, the pump should have enough submerged water level
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
Vacuum pump plus form must not reach a standard atmospheric pressure vacuum, so the general can absorb 8 meters is very good, and the self suction pump itself and loss, the horizontal self-priming pump can suck on basic 4~6 meters is very good, self-priming pump. Suction lift of 30 meters is purely in the Mongolian people, does not comply with the laws of nature, obvious anti science.
Q:Fire hydrant pump button, under what circumstances do not need to install?
General high voltage system, when normal, use small pump steady pressure.Fire hydrant button lifting pump is one of the multiple pumping methods, and it is an important link of reliable operation of the system.
Q:Any center of the pump
Alignment methods and requirements:1, check two feeler dial gauge or flange coupling the parallelism, usually with clearance between the both ends of the side instead of difference, in the circumferential direction every 900 measure, the maximum and minimum gap gap difference (Ab) less than or equal to 0.3 mm.2, the coupling flanges outside the park up and down, left and right four position to check whether they are in the same line, C less than or equal to 0.1 mm.When looking for a positive C, it will affect (a - b), finding the right (a - b) will affect the C, to balance each other. It's easier for an unskilled comrade to find C (a - b) first, and then find a positive one. Through the adjustment of the motor at the foot of the gasket thickness (Ab) and meet the requirements of C.Check the inlet and outlet piping before alignment. Make sure the weight of the inlet and outlet pipe does not exert force or torque on the pump. When looking for, should also pay attention to eliminate the pump rotor movement, so as to avoid the end gap error. If checked after the pump is working, it should be carried out under cold condition.It is important to draw attention to the fact that the pump set of the complete set of factory is only rough looking (checked with a ruler) when it is shipped. It may cause displacement when it is transported.
Q:What's the submersible pump?What is a submersible pump, and what about it?
Not afraid of water, because it is placed in the water itself to cool themselves, you can use for a long time. The amount of water pumped and the height of the water now basically meets the needs of a small amount of individual and a large number of factories. This is the submersible pump, the water pump in the water. You can see.
Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system?
Valve control system is generally used for open systems, through the proportional valve or servo valve flow changes to control the motor or cylinder actuator action. The advantages of the system are energy saving, heat generation, and control accuracy. The disadvantage is that the system is complex and the cost is higher.
Q:How to calculate the motor power of metering pump?
The motor power of the metering pump is divided into two parts1. mechanical power, this part of the power metering pump design part will be some data, mainly to control the mechanical structure of the metering pump required power
