The ZJB series vertical high-efficiency energy-saving self-priming pump is an ideal substitute for submersible pumps, long shaft pumps, submersible sewage pumps, ordinary self-priming pumps, fire pumps, and pneumatic diaphragm pumps, with strong adaptability. Widely applicable in fields such as steel, chemical, petroleum, power, metallurgy, environmental protection, construction, sewage treatment, pharmaceuticals, and tap water. Its different impeller modes and materials can transport various concentrations of media such as acid, alkali, salt, clean water, and sewage, and can also be designed and manufactured with corresponding materials according to different user needs. FEATURES 1. Efficient and energy-saving, with no bends in the inlet and outlet design, overcoming the loss of bends during the water flow process. The impeller and volute adopt special hydraulic model design and advanced production technology. Compared with ordinary self-priming pumps, their working efficiency can be increased by 20% -30%, and energy consumption can be saved by 20% -30%.
2. The water pump adopts a self-priming pump specific motor, equipped with branded bearings, with high precision, good reliability, long service life, smooth operation, no noise, and fast self-priming speed.
3. The whole machine has a long service life. The impeller, volute, and pump shaft are made of special alloy materials. In order to ensure the fit between the impeller and volute and achieve good water pump performance, the pump is equipped with a replaceable special alloy mouth ring at the fit between the impeller and volute, which can further extend the service life of the water pump. The pump shaft is equipped with a shaft sleeve, which does not come into contact with the medium, ensuring that the shaft will not be corroded. The operating life of the whole machine is 8-10 times that of submersible pumps and submersible pumps.
4. The water pump seal is cooled by oil, does not come into contact with the medium, and is equipped with a impeller power seal. Therefore, the water pump greatly improves the service life of the seal in situations where there are many impurities and harsh working conditions (such as iron oxide chips that are prone to wear and tear).
5. After installation, there is no need to add water again after the first water filling and start-up.
6. The water pump is a vertical structure, easy to install, with stable feet, compact structure, low infrastructure investment, and low operation and maintenance costs. The motor bearings are equipped with oil filling holes and oil drainage holes, making maintenance of the bearings very convenient.
7. The axial length of the water pump is short, easy to maintain, and does not require high maintenance space or large lifting equipment.
8. This water pump can be designed for axial suction and radial suction in any direction according to user needs, meeting different working conditions requirements. selection method 1. In the material code column of the performance parameter table, T G. The letters BXG represent the materials of the water pump, namely iron, steel (wear-resistant steel, alloy steel), and stainless steel.
If there are special working conditions, the water pump manufacturing adopts corresponding materials. Please contact our company for details.
2. Model meaning
ZJB 300-D1 ZJB represents vertical high-efficiency energy-saving self-priming pump
300 represents the diameter of the water pump inlet (mm)
D1 represents the performance parameter code
3. The inlet and outlet flanges of the water pumps produced by our company comply with the GB/T9119.2 standard, with a nominal flange grade of PN1.0. When our company's water pump leaves the factory, the whole machine includes the main engine, equipped with inlet and outlet flanges and filters for easy installation by users.
4. The matching motor voltage of the water pump is 380V, 3KV, 6KV, 10KV (50HZ), which can be selected by the user when ordering.
5. Selection Notice: When selecting this water pump, users should inform our company of the chemical properties of the medium in the operating environment, as well as density, viscosity, temperature, altitude, and self-priming depth, indicating the flow rate, head, and voltage level.
Special note: The parameters listed in this parameter table are the performance parameters of the water pump in clear water medium, and the head is the total head (including suction depth and outlet head). If there are special requirements, our company will be dedicated to designing and manufacturing for you.
