Product Description:

High pressure water pump, multistage vertical turbine pump

 Features

 

* Straight shaft structure, 2-pole motor,single phase with thermal protector

* Inlet and outlet section are cast iron,

* Impeller and hydraulic stack are PPO, It's economic and high cost-effective multistage pump

 

RANGE OF PERFORMANCE


8Flow rate up to 108 l/min (6.5 m3/h)
8Head up to 105m

 

LIMITS OF USE

 

 8Non-flammable or non-explosive clean liquid without solid grain or fibre.
8Liquid temperature up to 5 °C -  +60°C
8Environment temperature up to ≤  50°C

8Max. working pressure: 1.0 Mpa

 

INSTALLATION 


8These pumps are suitable for handling clean water without abrasive particles and liquids that are chemically 
non-aggressive to the pump components. Reliable, economical and simple to use, they are suitable for 
domestic use and in particular for distributing water in combination with small pressure sets, for irrigating gardens.
The pumps must be installed in a covered area, protected against the inclement weather.

Q:No negative pressure water supply equipment, both the main pump and auxiliary pump, power is not the same
1) microcomputer frequency conversion control cabinet2) water pump unit3) current stabilizing compensator4) vacuum suppressor5) all kinds of pipe fittings, valves and so on
Q:5 floor water pressure is too low, what kind of water pump is better?
Installed pump flow, lift did not meet the requirements, this will need to re type selection, calculation;
Q:Why should the pump be closed when the centrifugal pump is started?
On the other hand, the water on the pipe of the inlet pipe of the pump is stationary before the pump is opened, such as the sudden acceleration, and the water behind it can not keep up, which will cause the pressure of the inlet to drop suddenly and vaporize the water, and the centrifugal pump will be evacuated. (because of the centrifugal pump is rotating centrifugal force generated by the pump, leaf water and steam driven (gas) quality is very light, according to F= Ma, the centrifugal force is small, the pump can not be water sent).
Q:What are the problems that should be paid attention to when using vacuum pumps?
What are the problems that should be paid attention to when using vacuum pumps?
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
When the vacuum pressure is called vaporization pressure, cavitation is more than the surplus energy of vaporization pressure at the unit weight of the liquid in the pump suction port of the unit, with mark. The absorption process is to NPSH delta H: pump suction fluid allows the vacuum pump installation height is the unit of rice.
Q:How is the pump level of submersible sewage pump determined?
Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level
Q:What should be used to pay attention to the use of mechanical pumps?
Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test
Q:What kind of motor does the hydraulic pump need?
The motor should be determined according to the work environment, such as 220V.12V.24V.72V or 380V, and then the power.Calculation of actual oil pump power:
Q:Know flow and lift how to calculate the pump power?
The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.
Q:What's the difference between non negative pressure and variable frequency water pump?
Re pressure to a given pressure pressure zone water supply, than frequency conversion water pump energy savingFrom a health perspective, a water tank variable frequency water pump, water tank and the atmosphere, easy occurrence of water pollution two, no negative pressure equipment without negative pressure tank and pump and valve fittings etc., no water tank, the whole process of water supply of water is completed in a closed system, with air contact to avoid two pollution problems water supply.From the management point of view, no negative pressure is fully automatic intelligent operation, reduce management costs, no water tank, reducing the trouble of tank cleaning. No negative pressure is the upgrading of variable frequency water pump products
