Overview of hot water submersible pumps

Hot water submersible pump is the essential equipment to extract geothermal water. Can also be used for ponds, tanks, pressurized use. Specific can be used for hotel hot springs underground water, residential heating and so on.

Hot water submersible pump model description

For example: 250QJR100-20 / 1 250 that the application of the well diameter of not less than 250 mm.

Q that the diving (Hanyu Pinyin initial letter); J said well (Hanyu Pinyin initials). R means hot water (the first letter of Chinese pinyin)

100 means the flow rate is 100m3 / h; 20 means that the lift is 20 meters; / 1 means that the impeller is connected in series.

Scope of application

For enterprises and institutions such as: bath center, district heating, geothermal energy companies use power generation, extraction of underground hot water, according to different calibers we have different specifications for the user to choose models. The device low noise, high efficiency and save energy.

Technical Parameters:

1: Allowable operating water temperature range: +5 to +105 ℃

2: Solid impurity content (mass ratio) is not more than 0.01%

3: PH value (pH) 6.5-8.5

4: hydrogen sulfide content of not more than 1.5mg / L

5: chloride ion content of not more than 400mg / L

6: crew must completely invade the water work. Vertical use, select the model diameter and pump models to match, should not use large diameter diameter of small diameter pump, this is not conducive to the motor cooling.

Motor parameters

Hot water submersible pump motor lead length: 3m. If you need to extend the cable can call us in advance, submersible motor water lubrication, the use of the motor cavity must be filled with clean water, (Note: must be filled otherwise will reduce the motor life) If you forget to add water motor will Rapid burnout.

Motor protection class: IPX8

Electromagnetic wire adopts high temperature waterproof wire.

power supply

380V, the deviation does not exceed ± 5%, the frequency of 50HZ, the deviation does not exceed ± 1%, if the customer needs special voltage or special frequency need to inform us in advance.
