Condensate Pump

Type N, NB, NBA, GN, GNL Condensate Pump is used for delivering condensate water or other liquids which is physically and chemically similar to water in fire power stations with excellent suction performance. The temperature of the liquid pumped by type 100N130 and type 150N110 should be below 120℃, others below 80℃ Both type 100N130 and type 150N110 pumps can be used as scanty water after pouring cooling water in packing stuffer of type 100N130 pump and packing cover of type 150N110 pump.

Type N pump is horizontal, single-stage or multi-stage, cantilever and with inducer in structure. The main parts of pump are pump casing, pump cover, impeller, shaft, shaft sleeve and supporting parts. Type 3N6, 4N6, 4N6A and 100N130 pumps are horizontal cantilever single-stage condensate pump; Type 2.5N3×2,3N6×2 and 4N6×2 pumps are horizontal cantilever double-stage condensate pump; Type 6N6 and 150N110 pumps are horizontal cantilever single-stage condensate pump with inducer.  The bearing is supported by cantilever Bracket which is installed two rolling radial ball bearing, it can bear unbalanced axial force and get lubricated by dilute oil.

Type NB, NBA pumps are single-stage single-suction cantilever centrifugal pumps, it mainly consists of inlet, pump casing, impeller, shaft and shaft sleeve etc. The extending end is supported by one sliding bearing and two rolling bearings which get lubricated by grease.

Shaft seal is either soft packing seal or mechanical seal.

The pump is driven by motor through flexible coupling. View from motor end, the rotating direction of pump is counter clockwise.

Remarks: Other materials can be used according user’s requirement.
