1. PBDL is a shielded vertical multi-stage centrifugal pump that can ensure complete leakage prevention, and can transport liquids that are harmful to human health, the environment, and equipment, as well as expensive and prone to leakage.
2. Not capable of inhaling air, suitable for vacuum systems and conveying liquids that deteriorate upon contact with air.
3. The oil-free design can reliably transport liquids with high temperature, high pressure, low temperature, and increased temperature and pressure that are difficult to transport with general pumps.
4. 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.
5. The pump structure is reasonable, and a unique connection bracket is used between the motor and the pump. It 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, small volume, light weight, small footprint, smooth operation, easy installation, no need for adjustment, and convenient maintenance.
6. The impeller adopts an advanced hydraulic model, which has the characteristics of high efficiency and good performance.
7. The motor has no cooling fan, so the operating noise and vibration are very small.
8. The specification design of the pump inlet and outlet flanges is the same as that of standard valves, which facilitates pipeline layout. The pump room design should also be reasonable and practical.
9. The standardization and serialization of components are high.
10. The motor and junction box both adopt waterproof and explosion-proof structures, which can be safely used outdoors.
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. There is no automatic exhaust valve on the top of the motor. When the water pump is in use, simply open the inlet valve and release the air nozzle next to the exhaust valve. The air in the pump body and motor will be automatically discharged from the automatic exhaust valve on the top of the motor. After exhaust, it will be automatically closed immediately to prevent the medium from flowing out of the pump, ensuring the normal operation of the water pump. Moreover, if there is air entering the pipeline during use, it can be automatically discharged. This function eliminates the need for a dedicated person to frequently open the valve for exhaust, greatly reducing the cost and manpower of normal use.
13. The unique detachable structure enables the pump to be used and maintained normally, such as removing scale. When checking the wear of graphite bearings, simply remove the connecting screws between the motor housing and the lower end of the motor. In the top screw hole of the motor housing, the top motor and the fixed five components are located, making maintenance and regular inspections extremely convenient.

product overview

The PBDL series is a completely leak free and detachable vertical shielded multi-stage centrifugal pump. It is a new product of our company that absorbs and improves the advanced technology of shielded pumps internationally. It is a clever combination of shielded motors and vertical multi-stage pumps, which not only has the function of shielding low noise and zero leakage, but also has the performance of multi pump low speed and high head. The Yan series pump and motor are connected by a unique bracket. It 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 PBDL pump is also 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. PBDL is a detachable vertical shielded multi-stage centrifugal pump used for conveying 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.
