Product Description:

1. Brief Description


This JLM series of pump is a new type of highly efficient energy-saving household pumps,widely used in 

domestic household, well, tap water, vegetable garden, irrigation, water supply and water heater. It is and 

ideal solution for constant water supply in the circumstances of insufficient water pressure.


2. Working Conditions

Electric pump should be able to work normally and continuously under the following conditions.

1.WZB-A type transmission medium temperature of not more than 0-100°C.

2.Medium PH value between 6.5-8.5.

3.The solid impurities in the volume ratio no more than 0.1%, particle size less than 0.2mm.

4.The power frequency is 50Hz, voltage of single-phase AC 220V, 380V three-phase AC. 

Voltage fluctuation range of 0.9-1.1 times the rated value.

5.When the temperature is below 0°C ,should make anti freezing, when the pump is not use,open 

the waterproof screw on bottom of the pump body, drain water, in order to avoid cracking of pump body.

Reserve: Before JLm automatic use, make sure the pipeline without leakage.

Stainless Steel Multistage Booster Centrifugal Pump5. FAQ

1       Do you have self-priming pumps?

Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.

2       Is it really necessary to fit a bleed valve for the boxes?

It is always best to have a bleed valve as the gas produced by the fermenting sewage is potentially hazardous.

3       If I increase the power of the motor, must I also increase the power of the inverter?

You must select the size of converter that allows maximum absorption of the electric motor.

Q:About how to calculate the pump installation height?
When the water temperature is 4 degrees centigrade, the water pump is installed on the theoretical height of 10.33 meters, is the atmospheric pressure to the hydraulic pump inlet to the level of theory, in practical engineering, the water flow in the pipeline will produce resistance and other factors, the actual installation height generally less than 7 meters. The installation height limit of the pump shall be less than the design suction stroke of the pump.
Q:The difference between submersible pumps and centrifugal pumps
Submersible pump refers to the installation of pumps in the form of motor and pump body are installed underwater. It can be a sewage pump or a clean water pump or other purpose.Sewage pump to see the name will know, that is, playing sewage, you can use submersible pumps, you can also use other forms of pump.
Q:What is the function of open circulating water pump and shutdown in thermal power plant?
Open pump and closed pump, circulating water pump seems to be the full name of the pump, the industrial pump is to provide industrial water. Both open and closed pumps provide cooling water on the side of the machine, just because the requirements for water quality are different. Closed water is desalted water, while open water is recycled water.
Q:What does diving pump 80JYWQ40-15-1600-4 stand for?
3, sewage pump flow per hour 40 square water head 15 meters, 1600 rpm, with power 4KW
Q:What is the function of boiler feed pump, condensate pump, vacuum pump and low drain pump in operation?
The feed pump is a pump for supplying water to the boiler and maintaining the water level of the boiler. The condensate pump provides water to the deaerator after condensing the turbine and provides water for some condensate users. Vacuum pump is to maintain the vacuum of the pump, the pump is to lower the drain in a timely manner to the next level of low pump
Q:What does the lift of a pump mean?
Lift lift height = water raise height = total lift lift height + water = water is expressed in M by H (m)
Q:When using a frequency converter to adjust the pump, what is the relationship between the change of the speed and the efficiency of the pump?
The wind pumps such load is usually called square torque load, which is in a certain range of speed and torque is roughly proportional to the square of the speed of N, TL=kn^2, power and speed is proportional to the cube, the energy-saving effect is obvious.
Q:How does a pump pump water?
Centrifugal pump is centrifugal force, and household deep well pump is primary pressure
Q:Domestic pump does not turn, but the motor is energized what is the problem?
The motor is sure of electricity, isn't it? Is there a low voltage or broken phase (three-phase motor), these cases will cause the motor does not turn, or low speed (easy to block), so should be measured with a universal meter. Maybe the boot capacitor is broken. Or smell the smell of burning. It might be a short circuit between the motor windings. (bearings should be hard to break). Look for repairs if you suggest. You may not be good. Oh, capacitor. You can measure good and bad with a universal watch. If the capacitor is replaced, it is better to choose the same capacitor as the original configuration parameter.
Q:37KW how many contactors does the pump need to start directly?
Direct start requires 250A contactor.Contactor is divided into AC contactor (voltage AC) and DC contactor (voltage DC). It is applied to power, power distribution and power consumption. Contactor broadly refers to the use of coils in industrial electricity that flow through the current to produce a magnetic field, so that the contacts are closed so as to control the load of the appliance.
