The PBGDL column pump is a new type of pump that has the characteristics of energy saving, small footprint, easy installation, stable performance, and beautiful appearance. The outer shell is made of stainless steel, and a unique connecting bracket is used between the pump and the motor, which has the functions of easy disassembly and full sealing. The pump shaft and motor shaft are connected by a clamp type coupling, with high concentricity. And the axial force is solved by hydraulic balance, so the pump runs smoothly, with low noise and vibration, and the installation conditions are better than other types of pumps. It can be easily installed in the middle of any horizontal pipeline. The PBGDL pump is equipped with our company's B5 standard shaft shielded motor, which is highly versatile and extremely convenient for maintenance and repair
1. The PBGDL pump adopts a combination of multi-stage pumps and shielded pumps, effectively reducing the vibration and noise of the water pump, truly achieving the goal of ultra-low noise and zero leakage of shielded pumps, and meeting the requirements of users for high head water pumps. Can meet the high requirements of users for usage environment, usage scenarios, etc.
2. The PBGDL shielded pump can transport liquids that are harmful to human health, the environment, and equipment, as well as expensive and prone to leakage, due to its ability to ensure complete non leakage.
3. Not capable of inhaling air, suitable for vacuum systems and conveying liquids that deteriorate upon contact with air.
4. The oil-free design can reliably transport liquids with high temperature, high pressure, low temperature, and large temperature and pressure changes that are difficult for general pumps to transport.
5. Bearings use the conveyed liquid for self lubrication, without the need for lubricating oil, so they do not contaminate the conveyed liquid and eliminate the trouble of regular oil injection.
6. The PBGDL pump is equipped with the B5 standard shaft shielded motor produced by our company, which is highly versatile. At the same time, its unique detachable structure makes it extremely convenient for maintenance and repair.
7. A unique connection bracket is used between the pump and the motor, which has the functions of easy disassembly and full sealing. The pump shaft and motor shaft are connected by a clamp type coupling, with high concentricity. The connection between the pump and the motor has a detachable function. When the pump or motor needs maintenance, simply remove the bracket cover and then disassemble the clamp type coupling to remove the motor part, making maintenance extremely convenient.
8. The standardization and serialization of components are high.
9. The junction box adopts a waterproof and explosion-proof structure, which can be safely used outdoors.
10. The motor has no cooling fan, and the noise and vibration during operation are very low.
11. The newly adopted graphite bearings have the advantages of high wear resistance, low friction coefficient, anti-aging, and resistance to sediment and sand.
12. The top of the motor is equipped with an automatic exhaust valve. When the water pump is in use, simply open the inlet valve and release the air nozzle on the exhaust valve. The air inside the pump body and motor will be automatically discharged from the automatic exhaust valve on the top of the motor. After exhaust, it will automatically close immediately, preventing the medium from flowing out of the pump, ensuring the normal operation of the water pump. Moreover, if air enters the pipeline during use, it can automatically discharge it. This function eliminates the need for a dedicated person to frequently open the valve for exhaust, greatly reducing the cost and manpower of use.
13. The unique detachable structure of the motor allows the pump to be easily maintained during normal use, such as removing scale and checking the wear of graphite bearings. Simply remove the connecting screws on the lower end cover of the motor housing and push out the motor and stator components in the screw holes of the motor housing. Therefore, maintenance and regular inspections are extremely convenient.
14. Full protection electrical control box: This item is an optional accessory, which, together with the pre embedded thermal protector, water shortage probe, and water leakage probe in the motor, can provide comprehensive protection for shielding the motor. One - Overheating protection, the motor will automatically stop when the temperature exceeds the set value; 2、 Water shortage protection: When the circulating water in the motor is short of water, the motor cannot be started. If there is a lack of water inside during operation, the motor will stop. When there is water, the motor will automatically start again; 3、 Water leakage protection, when water leaks into the motor, the power will be immediately cut off and the motor will be stopped; 4、 Leakage protection will immediately cut off the power and stop the motor when there is a leakage situation.

product overview

The PBGDL series is a completely leak free and detachable vertical shielded multi-stage pipeline pump. It is a new product of our company that absorbs and improves the advanced technology of international shielded pumps. It is a clever combination of shielded motors and vertical multi-stage pipeline pumps, which not only has the function of shielding low noise and zero leakage, but also has the performance of multi-stage pumps with high head.
PBGDL is a vertical shielded multi-stage pipeline pump used for transporting clean water without solid particles and liquids with physical and chemical properties similar to water. The product is widely used in high-rise building water supply, construction site and urban water supply and drainage, petrochemicals, chemical industry, pharmaceuticals, textiles, nuclear power, military industry, shipbuilding, and fire protection. Heating, ventilation, refrigeration and other cold and warm water circulation pressurization. Especially in places with high requirements for vibration and noise, such as key projects, pump rooms, central air conditioning, research institutions, hospitals, etc. Due to the complete non leakage of this series of pumps, it can transport liquids that are harmful to the human body, environment, equipment, and are expensive and prone to leakage.
