GDL multi-stage pipeline centrifugal pump

overview

The GDL type vertical single suction multi-stage segmented pipeline centrifugal pump is a new generation of water pump product designed and manufactured by our unit in recent years based on excellent pump types at home and abroad, combined with user requirements and relevant fire safety standards, and in accordance with JB/TQ6435-92 standards.

The GDL type multi-stage pipeline centrifugal pump adopts a vertical segmented external stainless steel shell structure, which enables the inlet and outlet of the pump to be located on the same horizontal line and have the same diameter, and can be installed in the pipeline like a valve. It also concentrates the high pressure of the multi-stage pump, has the advantages of small footprint of the vertical pump and convenient installation of the pipeline pump. At the same time, due to the excellent hydraulic model used, it also has the advantages of high efficiency, energy saving, and smooth operation. The shaft seal adopts wear-resistant mechanical seal, with no leakage and long service life.

In order to better meet the requirements of users, our unit has also developed the GDLS type with the outlet located at the upper part. Its inlet and outlet can be installed at different relative positions (0 °, 90 °, 180 °), making it extremely convenient to use.

In order to provide users with safer and more reliable use of this type of pump, Shanghai Meiyanyi Pump Valve has specially developed a detachable structural type. In addition to all the advantages of GDL and GDLS, it also provides a more convenient, fast, and labor-saving way for you to replace vulnerable parts such as mechanical seals, making this type of pump more worry free to operate and maintain.

Application scope

The GDL type multi-stage pipeline centrifugal pump is mainly suitable for the circulation and pressurization of cold and hot water in high-pressure operating systems, parallel water supply of multiple pumps in high-rise buildings, fire protection, boiler feedwater and cooling water systems, and the transportation of various flushing liquids.

working conditions

1. This type of pump can transport clean water or liquids with physical and chemical properties similar to clean water;

2. Liquid temperature:- 15℃~+120℃;

3. Working pressure: The maximum working pressure is less than 2.5Mpa, which means that the system pressure is equal to the inlet pressure plus the pressure when the valve is closed, which is less than 2.5Mpa;

4. The temperature of the surrounding environment should be below 40 ℃, and the relative humidity should not exceed 95%;

5. When transporting corrosive media and hot liquids, please specify at the time of ordering so that special materials can be used to meet the usage requirements.

Installation instructions

1. The weight of the pipeline should not be borne on the pump during installation, otherwise it is easy to damage the water pump;

2. The pump and motor are integral structures that have been calibrated by the manufacturer before leaving the factory, so there is no need to adjust them during installation, making installation very convenient;

3. During installation, the anchor bolts must be tightened, and the pump should be checked at regular intervals to prevent loosening, in order to avoid severe vibrations during pump start-up that may affect its performance.

4. Before installing the water pump, carefully check whether there are any hard objects (such as stones, iron sand, etc.) in the pump flow channel that affect the operation of the water pump to avoid damaging the overcurrent components during the operation of the water pump;

5. For the convenience of maintenance and safety of use, a regulating valve should be installed on the inlet and outlet pipelines of the pump, and a pressure gauge should be installed near the inlet and outlet of the pump. For high lift pumps, to prevent water hammer, a check valve should also be installed in front of the outlet gate valve to cope with sudden power outages and other power loss accidents, so as to ensure that the pump operates under optimal conditions and increase its service life;

6. For working conditions where the liquid level is below the pump inlet and there is no vacuum pump, the installation method according to the installation diagram should be followed. The pump inlet should be filled before starting up and running. At the same time, the inlet pipeline should not have too many bends, and there should be no water or air leakage to avoid affecting the suction performance of the water pump.

7. To prevent impurities from entering the pump and blocking the flow path, a filter should be installed in front of the pump inlet to improve performance;

8. Before installing the pipeline, rotate the rotor components of the water pump without any friction sound or jamming phenomenon. Otherwise, the pump should be disassembled to check the cause.
