Maldives N, NB, and GNL condensate pumps

Condenser pumps are used in thermal power plants to convey condensate and other liquids similar to condensate. These pumps have good suction performance. Pumps of types 100N130 and 150N110 can convey liquids within 120℃, but other pumps cannot convey liquids exceeding 80℃. After cooling water is introduced into the stuffing box body and stuffing box cover respectively, pumps of types 100N30 and 150N110 can be used as condensate pumps.

Product Description

Overview

NB and NBA type pumps are single-stage, single-suction, cantilever centrifugal condensate pumps; GN and GNL type pumps are two-stage, single-suction centrifugal condensate pumps, used for pumping condensate from condensers and condensate from 750~3000 kW steam turbine generator sets, or other liquids with physical and chemical properties similar to water. Liquid temperature does not exceed 80℃.

Parameter Range

Flow rate Q 5~36m³ 3/h

Head H 25~62m

Applications

Condensate pumps are used in thermal power plants to transport condensate and other liquids similar to condensate. This pump has good suction performance. 100N130 and 150N110 type pumps can transport liquids below 120℃, but other pumps cannot transport liquids exceeding 80℃. 100N30 and 150N110 type pumps can be used as drain pumps after cooling water is introduced into the stuffing box and stuffing gland respectively.
