Tianjin Zhijiang Pump Industry ZJ150QJ Deep Well Submersible Pump

ZJ150QJ Deep Well Submersible Pump Model Description:
For example: ZJ150QJ30-150/18.5KW   ZJ represents the enterprise upgraded model; 150 indicates that the applicable well diameter is not less than 150 mm.
Q stands for submersible (the initial letter of the Chinese pinyin); J means for use in submersible wells; 30 indicates a flow rate of 30 m3/h; 150 indicates a head of 150 meters; 18.5KW indicates the motor power is 18.5KW.
ZJ150QJ Deep Well Submersible Pump Application Scope:
Suitable for agricultural irrigation, garden watering, rainwater recycling systems, urban water supply, and for extracting groundwater sources by enterprises and institutions. The equipment features low noise, high efficiency, and energy savings.
ZJ150QJ Deep Well Submersible Pump Technical Parameters:
Maximum unit outer diameter: 143mm; outlet diameters are 2", 3", and 4". Outlets are available with threaded connections or flange connections. If flange connection is used, the number of outlet fastening bolts is: 4 pieces, model 10×60 (grade 8.8), bolt center distance 110mm. To facilitate user installation, a matching flange (outer diameter 130mm, inner diameter 50mm/75mm, thickness 14mm) is specially provided with the unit outlet for on-site welding of the pump short pipe by the user.
ZJ150QJ Deep Well Submersible Pump Permitted Media Range:
1: Clear water without impurities, cooling water, rainwater, underground water from coal mines, iron mines, metal mines, drinking water, mineral water, seawater, etc.;
2: Permitted working water temperature range: +5 to +25°C (if high-temperature resistant models are selected, maximum temperature resistance is 180°C);
3: Solid impurity content (by mass) not greater than 0.01%;
4: Under normal conditions, pH value (acidity/alkalinity) 6.5-8.5; special materials such as 316, 316L, 2205 can be customized for special cases;
5: The unit must operate completely submerged in water.
ZJ150QJ Deep Well Submersible Pump Motor Parameters:
The submersible motor is lubricated by clean water. Before use, the motor cavity must be filled with clean water (Note: It must be filled completely; otherwise, the motor's service life will be reduced). If water is forgotten, the motor will burn out quickly.
Motor protection level: IPX8; Power supply: 380V/50HZ, 660V/50HZ. If customers require special voltage or frequency, please inform us in advance. Materials: Impeller/pump casing: Forged stainless steel 304; can be customized to tin bronze (various grades) such as ZCuSn3Zn8Pb6Ni1, 316, 316L, 2205, etc. Castings require customization. Cast iron HT200, or stainless steel such as 2Cr13, 304. Pump shaft: Stainless steel 2Cr13 (1050°C tempering treatment to enhance torque). Motor seal: Rubber seal O-ring; mechanical seal. Motor expansion adjustment bladder made of rubber.
ZJ150QJ Deep Well Submersible Pump Equipment Advantages:
Careful assembly in the factory ensures quick and reliable on-site installation. Each impeller in the factory undergoes dynamic and static balancing. The use of multi-stage impellers and precise machining accuracy ensures stable operation and minimal noise. Equipped with an internal check valve. High single-stage head reduces the overall unit height and increases operational stability. The pump shaft diameter is thickened to enhance torsional resistance. The shaft bush is made of pure natural rubber and composite materials for increased wear resistance, and is equipped with a hard shaft bush made of imported materials.
Supply scope: Submersible pump unit (including pump body and submersible motor), built-in one-way check valve, one matching flange for the outlet, 4 pieces of 10×60 (grade 8.8) bolts (only for models with flange connections), one user maintenance manual, one certificate of conformity, one packing list, and outer packaging.
