Such as: boiler high-temperature wastewater, high-temperature wastewater in water pipelines, high-temperature wastewater circulation in cooling pipelines, emergency repair departments for power, pumping and draining wastewater from heating pipelines, factory cooling water circulation, etc.

Tianjin Zhijiang Pump Industry ZJ400QR Hot Water Submersible Pump Technical Parameters

Outlet flange diameter 700mm. Number of fixing bolts is 12, model 16*80 (grade 8.8), bolt center distance 325mm. To facilitate user installation, a matching flange consistent with the unit's outlet is specially provided ex-factory; users are to weld the pump short pipe on-site themselves.

Tianjin Zhijiang Pump Industry ZJ400QR Hot Water Submersible Pump Permissible Medium Range

1. High-temperature industrial wastewater without impurities

2. Permissible working water temperature range: +5℃ to +125℃

3. Solid impurity content (by mass) not greater than 0.01%

4. pH value (acidity/alkalinity) 6.5—8.5. If the pH value is out of range, please inform us in advance so we can switch to stainless steel, tin bronze, or other corrosion-resistant materials.

5. Hydrogen sulfide content not greater than 1.5 mg/L

6. Chloride ion content not greater than 400 mg/L

7. The unit must be completely submerged in water.

Tianjin Zhijiang Pump Industry ZJ400QR 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, it will reduce the motor's service life. If water is forgotten, the motor will burn out quickly. For specific parameters, see the motor nameplate).

Motor protection grade: IPX8

Power supply: 380V/660V/1140V/3000V/6000V/10000V, 50HZ /60HZ. If customers require special voltage or frequency, please notify us in advance.

Materials

Pump casing materials include: cast iron 200HT; stainless steel or tin bronze. Specific materials are provided according to the technical agreement between both parties.

Pump shaft: stainless steel 2Cr13; duplex stainless steel; 17-4, etc. The material we provide varies depending on the environment, and will be provided according to the technical agreement.

Motor expansion adjustment bag rubber material.

Tianjin Zhijiang Pump Industry ZJ400QR Hot Water Submersible Pump Equipment Advantages

--- Easy installation, no complex infrastructure investment, just place it in the pool to use;

--- Multi-stage impeller design, extremely low noise;

--- Built-in check valve to prevent water hammer impact;

--- High single-stage head, which can reduce the overall height of the unit and increase operational stability. The pump shaft diameter is 450mm, enhancing the shaft's torsional resistance. The shaft bush is made of natural rubber material for better wear resistance and is equipped with a hard shaft bush made of imported material.
