Tianjin Zhijiang Pump Industry ZJ150QR Hot Water Submersible Pump

ZJ150QR Hot Water Submersible Pump Model Description：
For example: ZJ150QR30-150/18.5KW   ZJ represents the enterprise upgraded model; 150 indicates that it is suitable for well diameters not less than 150 mm.
Q stands for submersible (the initial letter of the Chinese pinyin); R indicates high-temperature resistance or use in hot water environments such as hot springs; 30 means the flow rate is 30 m3/h; 150 means the head is 150 meters; 18.5KW indicates the motor power is 18.5KW.
ZJ150QR Hot Water Submersible Pump Application Range：
Suitable for farmland irrigation, garden watering, rainwater recycling systems, urban water supply, and extracting groundwater sources for enterprises and institutions. The equipment features low noise, high efficiency, and energy savings.
ZJ150QR Hot Water Submersible Pump Technical Parameters：
Maximum outer diameter of the unit: 143mm; outlet diameters are available in 2", 3", and 4". Outlets can be threaded or flanged. For flanged connections, the number of fastening bolts is 4, model 10×60 (grade 8.8), with a bolt center distance of 110mm. To facilitate installation, a matching flange (outer diameter 130mm, inner diameter 50mm/75mm, thickness 14mm) is provided with the unit for on-site welding to the pump short pipe.
ZJ150QR Hot Water Submersible Pump Permissible Medium Range：
1: Clear water without impurities, cooling water, rainwater, underground water from coal, iron, and metal mines, drinking water, mineral water, seawater, etc.;
2: Permissible working water temperature range: +5 to +25°C (if high-temperature resistant model is 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 specific conditions;
5: The unit must operate fully submerged in water.
ZJ150QR Hot Water 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 rating: 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; customizable 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 for enhanced torque). Motor seal: Rubber seal O-ring; mechanical seal. Motor expansion adjustment bladder made of rubber.
ZJ150QR Hot Water Submersible Pump Equipment Advantages:
Careful assembly in the factory ensures quick and reliable on-site installation. Each impeller undergoes dynamic and static balancing. Multi-stage impellers and precise machining ensure stable operation with minimal noise. Built-in check valve. High single-stage head reduces overall unit height and enhances operational stability. The pump shaft is thickened to improve torsional resistance. The shaft bush is made of natural rubber and composite materials for increased wear resistance, and includes 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, four 10×60 (grade 8.8) bolts (only for flanged outlet models), one operation and maintenance manual, one certificate of conformity, one packing list, and outer packaging.
