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

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

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

■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.

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

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

■Vertical structure, the pump is coaxial with the motor, and the axial dimension is short, which makes the pump run more smoothly and has low noise.

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

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

■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.

■Surface chromed shaft prolongs the life for itself.

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

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

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