GDL
Cast Iron Multistage Booster Jockey Pump features energy saving, small footprint, easy installation and stable performance. The jacket is made of 1Cr18Ni9Ti high-quality stainless steel. The shaft seal is made of wear-resistant mechanical seal, no leakage and long service life. The hydraulic force balance solves the axial force, so the pumping brick is stable and low noise, and can be easily installed in the middle of a horizontal pipeline.
Application range
The GDL
Cast Iron Multistage Booster Jockey Pump can be used to transport clean water without solid particles and liquids with physical and chemical properties similar to water. Mainly used for fire hydrant water supply, sprinkler system water supply, fire system voltage regulation, other occasions such as residential, hotels, office buildings, commercial buildings, factories, hospitals, etc. cleaning liquid and fire water delivery.
Features
● Easy installation and maintenance: The pump suction port and the spout outlet are horizontal, which simplifies the connection of the pipeline (pipeline installation, import and export can be installed at any position and any direction of the pipeline like a valve, and installation and maintenance are extremely convenient);
● Beautiful appearance: Stainless steel jacket and pipe structure, beautiful appearance;
● Less operation, maintenance costs: The use of reliable mechanical seals, low failure rate, with less operating and maintenance costs;
● Low cost: The use of high-speed motor, so that the pump has the characteristics of light weight, small size, low cost;
● Unique components, reduce noise: Unique hydraulic components design, good overcurrent performance, to minimize flow noise.
Precautions for use
● The jockey pump is made of stainless steel shaft and aluminum bronze impeller (national fire acceptance standard). If there are different material requirements, please specify separately when inquiring (ordering).
● The jockey pump should be started at least once every six months to prevent difficulty in starting again due to long-term use or poor maintenance.
● The water inlet pipeline must be highly sealed and must not leak or leak air;
● It is forbidden to run the pump for a long time under cavitation;
● It is forbidden to run the motor over-current for a long time when the pump is running under high flow and low lift conditions;
● Regularly check the motor current value during pump operation, and try to make the pump run within the design working conditions;
● The pump should be supervised during operation to avoid accidents;
● After long-term operation of the pump, due to mechanical wear, if the noise and vibration of the unit increase, stop the inspection and replace the vulnerable parts and bearings if necessary. The overhaul period of the unit is generally one year.
● Maintenance and maintenance of mechanical seals:
1). Mechanical seal lubricating fluid should be cleaned without solid particles;
2). It is strictly forbidden to work in the case of (dry) dry grinding;
3). Drive the pump (motor) several times before starting to avoid the mechanical seal breakage damage caused by sudden start.
