The GZB series of new high-efficiency and energy-saving self-priming pumps are optimized and upgraded on the basis of the WFB-type seal-free automatic self-priming pump. The sealing device is designed with a combined labyrinth centrifugal airflow seal. During the operation of the water pump, the sealing device and the pump cover sealing part are clearance-matched, which does not produce mechanical friction and wear, and permanently solves the problem of seal leakage. The water pump of this structure forms gas-water separation in the pump chamber through the centrifugal force generated by the rotation of the impeller, and the gas in the pump chamber and the inlet pipe is discharged efficiently and quickly. The conveying medium enters the pump chamber under the action of atmospheric pressure to achieve a stable and reliable self-priming function. The self-priming function of the water pump can be realized without any auxiliary vacuum devices. To meet the chemical characteristics and temperature requirements of different industries and different media, a variety of pump assembly materials with corrosion resistance, high-temperature resistance, and cavitation resistance are designed and produced. At present, we can provide complete sets of duplex stainless steel 2507 and 2205 materials; stainless steel 316L, 304 materials, wear-resistant alloy steel JM3 ~ JM6 materials, cast steel ZG35, ZG45 materials, ductile iron QT400, QT500 materials; cast steel HT250, HT300 and other full series of corrosion-resistant and explosion-proof pump assemblies.

READ MORERegular inspection and cleaning
After the GZB series high efficiency energy saving self-priming pump is put into use, a maintenance plan for regular inspection and cleaning must be established. As the pump continues to run, impurities, corrosive substances or sediments may accumulate inside, which will not only affect the normal operation of the pump, but may also cause a significant decline in performance. Therefore, regular cleaning of the pump body and related components is the basis for ensuring the performance of the equipment.
The specific cleaning steps are as follows:
Close the inlet and outlet valves of the pump body to ensure that the operation of the pump is stopped to avoid accidents during the cleaning process.
Open the pump body for inspection, carefully clean the impurities, sediments or rust accumulated in the pump, and ensure the cleanliness of the environment inside the pump.
Check key components, including impellers, bearings and seals, to confirm whether they are intact. If wear or damage is found, it needs to be replaced in time to prevent the overall performance of the pump from being affected.
Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. has first-class production and testing equipment, and has carried out in-depth cooperation with colleges and universities such as the Fluid Technology Research Center of Jiangsu University and Lanzhou University of Technology. This cooperation not only promotes technological innovation and optimization, but also ensures the leading position of GZB series self-priming pumps in the market. Regular cleaning and inspection help maintain the efficient operation of the equipment, thereby saving customers more operating costs.
Bearing and lubrication maintenance
In the operation of GZB series high efficiency energy saving self-priming pump, bearings are key components and their maintenance is essential. Bearings generate heat due to friction during operation. If they are not lubricated in time, they will cause increased wear and may even cause bearing damage, which will affect the normal operation of the pump. Therefore, it is recommended to carefully inspect the bearings of the pump during each maintenance and replenish or replace the lubricating oil in time according to the operating conditions of the equipment.
Maintenance requirements are as follows:
Check the state of the lubricating oil to ensure that it is sufficient and free of impurities and pollution to ensure the lubrication effect.
Regularly replace the lubricating oil to avoid deterioration of the lubricating oil due to high temperature or long use time, which affects the lubrication effect.
Monitor the wear of the bearings. If abnormal vibration or noise is found, replace them in time to prevent greater damage to the equipment.
Seal and pump body inspection
The GZB series self-priming pump has significantly improved the reliability of the equipment with its innovative non-sealed structure design, and successfully avoided the common leakage problems of traditional sealed pumps. Despite this, the sealing structure may still be affected by wear or aging during the long-term operation of the equipment, so it is particularly important to regularly inspect the pump body and seals. Special attention should be paid to the following aspects during maintenance:
First, the aging and wear of key components such as seals and O-rings must be checked regularly. Aged sealing materials may cause the sealing performance to deteriorate, thereby causing leakage.
Second, if a slight water leakage is found in the pump body, the seal must be replaced immediately or necessary repairs must be made to prevent the problem from further deteriorating and affecting the normal operation of the pump.
In addition, it is the top priority of maintenance work to regularly check the sealing status of the pump cover, sealing contact surface and the inner wall of the pump body to ensure that the sealing performance remains in the best condition. Any minor defects may lead to a decline in overall performance.
Jiangsu Double Wheel Pump Machinery Manufacturing Co., Ltd. fully considered the efficiency and reliability of the sealing system when designing and manufacturing the GZB series high efficiency energy saving self-priming pump. Its unique sealing design is not only the basis for the long-term stable operation of the equipment, but also the embodiment of the company's strict quality control and technological innovation. Through regular inspection and maintenance, users can further improve the reliability of the equipment and significantly reduce the occurrence of failures, thereby ensuring the continuity and efficiency of production.
Impeller and pump body internal inspection
The impeller of the GZB series self-priming pump is the core component of the pump, and its performance directly affects the water absorption capacity and delivery efficiency of the pump. During long-term use, the impeller may deteriorate due to wear, corrosion or intrusion of impurities. Therefore, it is very important to regularly check the wear and cleanliness of the impeller. The specific requirements are as follows:
After each stop of the pump, the impeller needs to be checked to confirm whether it has obvious wear or deformation. This link is the basis for ensuring the normal operation of the pump body.
When cleaning the impeller, be sure to ensure that there are no foreign objects, sediments or other impurities on its surface that may hinder the flow of water. Any residue may affect the water absorption performance of the pump.
If the impeller is found to be damaged or the efficiency is reduced, it needs to be replaced in time to ensure the operation of the pump.
