■ PBG series pipeline shielded pump product overview:
.jpg)
Pipeline shielded pump, vertical centrifugal shielded pump, single-stage pipeline shielded pump
The PBG series pipeline shielded pump is composed of a centrifugal pump and a shielded electric motor, forming a sealed whole with a static sealing design. It can be widely used in the transportation of non corrosive cold and hot water in heating, sanitary water, and chilled water systems. It is an ideal transportation equipment for heat exchange stations and pipeline centralized heating in hotels, hospitals, factories, high-end residences, and other places. Compared with ordinary centrifugal pumps, shielded pumps have the characteristics of compact pump machine integrated structure, small volume, beautiful appearance, smooth operation, easy installation, no noise, zero leakage, etc., which maximize the satisfaction of users' increasing demands for stability and environmental protection in the working environment.

For vertical water pumps, electric pumps consist of two parts: a water pump and a shielded electric motor (hereinafter referred to as the motor). The main components of the water pump include impeller, pump body, and sealing ring, while the main components of the motor include stator, rotor, shielding sleeve, bearing seat, bearing, thrust disc, cooling pipe, and air release valve.
The shielded pump motor uses H-grade insulated windings. The rotor consists of a stainless steel shaft and a cast aluminum rotor. In order to prevent the liquid from entering the stator and corroding the rotor, stainless steel shielding sleeves are used to seal the inner diameter of the stator and the surface of the rotor.
Sealing: The connection between the pump body flange and the motor flange, as well as the connection between the machine base, bearing seat, and stator shield, are all sealed with heat-resistant O-ring seals.
The shield pump impeller cantilever is installed on the motor shaft and secured with keys and nuts.
Lubrication and cooling: using external circulation. When the pump is working, a small amount of liquid is drawn out from the outlet of the electric pump and flows through the cooling pipe, the clearance between the rear bearing and the shaft neck, the clearance between the stator and rotor, the clearance between the front bearing and the shaft neck, and the rear mouth ring of the impeller to form a circulation loop (single-stage), and the inlet ring of the last stage impeller to form a circulation loop (multi-stage).
■ Model meaning:
■ Working conditions:
1. The fluid transported by the shielded pump should not contain solid particles with a volume ratio exceeding 0.1% and a particle size greater than 0.2mm;
2. The rated voltage of the power supply is 380V, the frequency is 50Hz, and it is three-phase AC power;
3. The temperature of the conveyed liquid is ≤ 120 ℃;
4. The pressure of the shielded pump system shall not exceed 1.0MPa and shall not be less than 50Kpa; If it exceeds the limit, please indicate it when placing the order;
5. The ambient temperature shall not exceed 40 ℃;
6. Altitude not exceeding 1000mm;
7. The electric motor is of the squirrel cage type and is suitable for full voltage starting. If the original capacity of the motor is insufficient for full voltage starting, voltage reduction starting can be used.
■ Product Usage
Widely used in HVAC cold and hot water circulation, industrial and urban water supply, pipeline pressurization, long-distance water delivery and other occasions, derivative products with different materials are more suitable for petroleum, chemical, pharmaceutical, food, refrigeration and other industries. Various occasions including high, low, and high pressure.
