Detail

Overview
N-type condensate pump is used to transport condensate water and other liquids similar to condensate water in thermal power plants. The pump has good suction performance. 100N130 and 150N110 pumps can deliver liquids within 120 ℃, and other pumps cannot deliver liquids at a temperature exceeding 80 ℃
100N130 and 150N110 pumps can be used as drain pumps after cooling water is introduced into the stuffing box body and packing gland respectively.
Performance range
Flow rate:Q = 8 ~ 720m ³/h
Head: H = 38~186m
Drive
The pump is driven by an electric motor through an elastic coupling. Viewed from the drive direction, the pump rotates counterclockwise.
Model Description

Structure
The pump is horizontal, single-stage or multi-stage, cantilever type and with inducer and other structural forms.
3N6, 4N6, 4N6A and 100N130 pumps are single stage condensate pumps. 2.5 N3x2, 3N6x2 and 4N6x2 pumps are two-stage condensate pumps. The 6N6 and 150N110 pumps are single stage condensate pumps with inducer.
The pump is sealed with soft packing. A replaceable shaft sleeve is installed at the shaft seal.
