Product Introduction:
1. WQ(D)-S stainless steel casting sewage submersible pumps use impeller structure of single or double channel, which improves sewage discharge capacity. It can discharge fibers which are five times larger than the pump caliber and solid particles which are as large as 50% of the outlet caliber.
2. It uses VITON double mechanical seal, radial "O" ring, which perfects seal function of the pump.
3. With precision casting casing, it is corrosion-resistant, energy-saving, light, beautiful, easy to maintain, free from the pump room and able to serve as soon as put into water. Therefore, it can reduce the construction cost.
4. Please install overheating and over-current protector to avoid the motor overloading.
5. For high-temperature liquid, corrosion resistant cable, TEFLON mechanical seal can be choosed.

Q:Water pump belongs to power equipment or mechanical equipment?
It's mechanical equipment!
Q:What does "ETA" mean in the selection of pumps?
NPSH refers to the cavitation, the pump is the technical parameters
Q:Does the lift of pump relate to the water level of import and export?
Pump head refers to the inlet and outlet pressure head, that is to say, the entrance resistance greatly affects the pump lift, of course, this inlet resistance has a degree, too large water pump does not bring water or cause water pump cavitation. If the water level at the pump inlet is the same height, the inlet flow resistance of the pump may not be considered.
Q:Electrical design into!!! Is the water pump lamp waterproof?
The ordinary pump houses are ordinary energy-saving lamps, but there is a glass shield outside of it which is waterproof...And they're all emergency lights!Like some large pump houses, they have riot lights...
Q:How can the pump be stationary?
Rusty, turn with your hands to see the situation, the two bearings filled with lubricating oil.
Q:What is the function of the pump?
Pumps are usually used to enhance the liquid, conveying a liquid or liquid to increase the pressure, that is the original motive of the mechanical energy so as to achieve variable liquid fluid energy machine called pump.The technical parameters of measuring water pump include flow, suction, lift, shaft power, water power, efficiency, etc. according to different working principles, they can be divided into volumetric pump, vane pump and so on. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:Do you need a stop valve for the pump at home?
Pump used at home do not take the water stop valve, the water level is too low, it can not pump up. In addition, there is no stop valve, not immediately pumping water, will have to wait a short time.The valve is actually a floating ball valve, when water is accumulated to a certain height, the float top, open the valve linkage; row water, reduce the water level, the valve is automatically closed, it realizes automatic drainage to steam pipeline.
Q:Diving pump voltage
Small amount of water, it should be the lift can not meet the requirements, change the submersible pump is the best solution. With 380 volts, it is very likely to burn out the pump motor.
Q:How to change the frequency of a water pump with a pump?
I have encountered this problem, 1, check the reverse pump outlet single flow valve is damaged2. Check whether the three wires of the motor are in wrong position and reverse when starting
Q:What is the relationship between pump power, lift and flow?
The pump power is more marked discrepancies in the actual application, power flow, power and small traffic hours, head directly determines the flow, high lift flow is small, the power is small. This view is the largest public understanding of the subversion of the original. I 1.1KW a self suction pump the actual operation of the power, it is able to explain this, 1.1KW would say 1.1 per hour of electricity, but I made a note of the meter, the per hour only 0.6 degrees, no wonder people say the true power of pump not so much, such as 1.1KW, said to be only 750W this is true, I believe. The rated power of pump or need to reach the normal traffic to its go to this value, or is the virtual standard, industry inertia. I put the home pump is pumping, water is two hundred or three hundred meters away a shallow river, because of the long distance, flow Volume is not very large, basically only rated 1/3 bar, and I do not know is the flow of low power consumption reduction, or the actual power of the pump did not mark that big, it is still under exploration...
