Product Overview:
The SG series single-stage pump—featuring eight major advantages—was successfully developed in the 1980s, becoming one of the first products of its kind introduced to the heating and air conditioning engineering sectors in China. Following the evolution through the SG series, ISG series, and the third through sixth generations of the KQL/W series, the product line returned to the high-quality, high-efficiency SG series in 2021.
