Using reliable quality motor,380V or 220V or direct current machine is optional.

 

 

 

Features

 

1.Very high safety of operation. Mechanical actuate diaphragm. Changeable eccentric drive

 

2.Power off seal,no leakage,with security delivery device,simple maintance

 

3.It can transport high-viscosity mediums, corrosive liquid and dangerous chemical goods.

 

4.The flow can be controlled via adjusting the length of stroke or the motor frequency.

 

5.The diaghragm is made from multilayer complex structure to promote the life span, the first layer is Teflon anti-acid diaphragm, the second is EPDM stretch rubber, the third is 3.00 mm thick SUS304 that supporting the iron corn. The fourth is also the EPDM stretch rubber to cover all of the body.

Q:Piston filling and peristaltic pump filling which precision is high?
If the unit area is large, the accuracy of the plunger is certainly not high. The peristaltic pump is used by means of extrusion roller extrusion pump to promote the solution, this also depends on the unit cross section size, the same motor accuracy is very important.
Q:How many square cables does the submersible pump for 7.5KW need?
I=P/ (1.732Ucos phi) =7.5/ (1.732X0.38X0.85) =13A (calculated according to three-phase city power, power factor 0.85).
Q:What are the reasons for sealing damage of centrifugal pumps?
Two, cavitation. Cavitation (mainly from a thermal centrifugal pump).Because the medium is hot water, the water temperature is too high to produce steam, the gas in the pipeline enters the pump cavity height, and the part of the gas can not be discharged, thus causing water shortage to run, the machine seal dry grinding is invalid, and the cavitation erosion device is not available.Process: replace the machine seal.
Q:What's the meaning of the pump head in the water pump, please advise, thank you
According to China Wikipedia network, the basic components of the water pump: motor, coupling, pump head (body) and chassis (horizontal).Pump is generally composed of pump body and pump head, in which the pump body refers to the spiral case, impeller, bearing, oil shell and sealing assembly, etc., the pump head refers to the impeller, bearings, oil ring and sealing rotating parts (including shaft), etc..
Q:Roots pump and dry pumpRecently, the work involved in the vacuum pump, do not understand this, is a ads602 vacuum pump
The front stage pump to a certain pressure to start the roots pump, roots pump has advantages of is at the entrance of low pressure gas pumping speed is high, popular point is in high vacuum pumping speed is still relatively large. With the former pump can achieve different limit the vacuum is different.
Q:What is the pump delivery? What's the difference between years and years?
Secondly, the landlord asked the question, although I did not go to the insurance company to practice the operation, but to my four years of learning, as well as internship experience, or can help you analyze, and I hope to help you.Pay is a one-time payment of premium -- all wholesale D sea n
Q:Water pump spoon pipe for power plantWhich hero can tell me what is the water pump spoon tube ah? And its role
Then control the speed level, to achieve the purpose of regulating the speed and flow of the feed water pump.
Q:What is the function of the heating pump system for the water pump design?
As the feed water temperature is higher, in the case of non warm pump start, will make the pump body is subject to greater thermal impact; in addition, the flow components with the pump contact heating fast, not contact with water directly heating slowly. This expansion due to uneven speed, it will inevitably produce thermal stress, deformation of the pump body, sealing surface, the joint surface is lax and leaking phenomenon. Therefore, the warm water pump system is designed for the water pump.
Q:What is the lift of diaphragm pump?
Diaphragm pump lift is different from the centrifugal pump, refers to the diaphragm pump can raise the height of water, the unit is meters water column. Lift depends on the size of the outlet pressure, the pressure per kilogram is equivalent to 10 meters height
Q:Why is the sewage pump device coupler?
The automatic coupling device but the installation of GAK type submersible sewage pump, need lifting, people may not need to unscrew the screw water, the water pump can directly improve, after repairing down along the guide rail can realize sealing pump and pipeline, water pump and normal operation. Small sewage pump can be installed freely, large sewage pumps are generally equipped with automatic coupling device, automatic installation, installation and maintenance is very convenient.
