Biref introduction:
GFL series is a maintenance free vertical centrifugal pump of single stage and single suction structure. It is an updated product based on old series ISG,which is manufactured based on ISO2858 standard,therefore its noise is sharply reduced.And it is maintenance free,and its life has been multiply prolonged. Meanwhile,according to the different temperature and environment,the models of hot water and low noise are derived from GFL series,such derivatives conform to the requirements of the updated national standard JB/T53058-93.

Parameters:

1. Flow rate:Q=1.5~2450 (m³/h)

2. Total head:H=8~150 (m)

3. Pump speed:n=1450rpm/2950rpm

4. Fluid s.g.:γ ≤1.1

5. Fluid temperature:T=0~120ºC 

6. Pump diameter:40~500mm

Features:

1. Conforms to the requirements of JB/T53058-93,adopts the performance parameters of IS centrifugal pump,vertical type in structure.

2. Advanced hydraulic models of high efficiency,with features of smooth operation,no leakage and low noise.

3. Updated and unique structure,requires smaller space for installation,save 40%~60% investment on site construction.

4. The pump shaft and motor shaft are 100% aligned;impeller is strictly static and dynamic balance tested,ensures no abnormal vibration in the high speed operation.

5. Maintenance free mechanical seal and shaft which made from titanium and tungsten carbide,with good sealing performance; Non-breakdown operation and long life.

6. With as many as 219 specifications,GFL series is the ideal product to replace old ISG series vertical centrifugal pump.

Structure:

1. Vertical structure,100% aligned shaft enables smooth operation and low noise.

2. Impeller is directly assembled onto the end of lengthened shaft of motor,thus reduced the pump dimension.

3. Pump inlet and outlet flanges share the same dimension and horizontally in a straight line; Pump is directly installed in the pipeline,which brings convenience for the pipe arrangement.

4. Surface chromed shaft prolongs the life for itself.

5. Canceled the traditional shaft sealing,eliminated the possibility of leakage.

6. Based on the requirements,it can be operated by series connection and parallel connection.

7. Can be vertically and horizontally installed according to the requirements of pipe arrangement.

1. Configurations:

2. 

3. Applications:

4. Water supply to water tank of high buildings and fire pump.

5. Boiler feed pump,circulation pump for boiler.

6. Cold and hot water circulation pump for air conditioner.

7. Hot water pump for producing facilities.
