Overview of N, NL type condensate pumps
N, NL type condensate pumps are used for conveying condensate water and other liquids similar to condensate water in thermal power plants. The pump has better suction performance. 100N130 and 150N1 10-type pumps can transport liquids within 120℃, and the temperature of other pumps cannot exceed 80℃. 100N130 and 150N1 10 pumps can be used as drain pumps after cooling water is passed through the packing box body and the packing gland respectively.
Performance range
Flow rate Q=8～120m³/h
Head H=38～143m
structure
The pump has various structural forms such as horizontal, single-stage or multi-stage, cantilever type and with inducer. 3N6, 4N6, 4N6A and 100N130 type pumps are single-stage condensate pumps 2 5N3×2, 3N6×2 and 4N6×2 type pumps are two-stage condensate pumps. The 6N6 and 150N110 pumps are single-stage condensate pumps with induction. The pump is sealed with soft packing, and a replaceable shaft sleeve is installed at the shaft seal.

Transmission
The pump is driven by an electric motor through an elastic coupling. Viewed from the drive direction, the pump rotates counterclockwise.
