Product Features
1. The PBQDL pump adopts a combination of stainless steel 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. This series of pumps adopts a vertical segmented structure with a stainless steel shell. The water pump part is made of stainless steel sheet stamping and welding, which has the characteristics of compact structure, light weight, corrosion resistance, environmental protection, high efficiency and energy saving, small footprint, and beautiful appearance.
3. The inlet and outlet of PBQDL screen are located on the same horizontal line and have the same diameter. It can also be divided into one: thin plate stamping flange connection; 2： Card sleeve connection; 3： External movable joint with internal thread connection, featuring convenient pipeline layout and installation.
4. The PBQDL pump is equipped with the B5 standard shaft shielded motor produced by our company, which has a high degree of universality. At the same time, its unique detachable structure makes it extremely convenient for maintenance and repair.
5. 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.
6. Not capable of inhaling air, suitable for vacuum systems and conveying liquids that deteriorate upon contact with air.
7. 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.
8. The standardization and serialization of components are high.
9. The motor has no cooling fan, and the noise and vibration during operation are very low.
10. The newly adopted graphite bearings have the advantages of high wear resistance, low friction coefficient, anti-aging, and resistance to sediment and sand.
11. 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.
12. 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.
13. 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 PBQDLF 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.
PBQDLF 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.
