Brief Introduction:

The GFL series is a maintenance-free vertical centrifugal pump with a single-stage and single-suction design. It is an upgraded version of the older ISG series, manufactured according to the ISO2858 standard, which significantly reduces noise levels. The pump is designed for long-term operation without maintenance, and its service life has been greatly extended. Additionally, based on different temperature and environmental conditions, there are hot water and low-noise versions derived from the GFL series, which comply with the updated national standard JB/T53058-93.

Parameters:
 

Flow rate:	Q=1.5~2450m3/h
Total head:	H=8~150m
Suction head:	H=5~7m
Speed:	n=1450rpm/2950rpm
SG.:	γ ≤1.1
Temperature:	T=-0~120ºC
Pump diameter:	40~500mm

Features:

1. Complies with the requirements of JB/T53058-93, adopts the performance parameters of IS centrifugal pumps, and has a vertical structure.
2. Advanced hydraulic models with high efficiency, smooth operation, no leakage, and low noise.
3. Updated and unique structure, requiring less space for installation, saving 40%~60% on site construction investment.
4. The pump shaft and motor shaft are 100% aligned; impeller is strictly static and dynamic balance tested, ensuring no abnormal vibration during high-speed operation.
5. Maintenance-free mechanical seal and shaft 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 pumps.

Structure:

1. Vertical structure, 100% aligned shaft enables smooth operation and low noise.
2. Impeller is directly assembled onto the end of the lengthened shaft of the motor, thus reducing the pump dimension.
3. Pump inlet and outlet flanges share the same dimension and are horizontally in a straight line; pump is directly installed in the pipeline, which brings convenience for 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.
