LDTN series condensate pumps are suitable for conveying condensate water in condenser hot wells under high vacuum conditions in thermal power plants, biomass power generation and self-provided electric generator sets, and can also be used in NPSH or chemical processes with limited installation bases. The physicochemical properties are similar to the medium of water. LDTN, LDTNA, LDTNB pumps are all vertical barrel type structures. The suction and discharge ports of the pump are located on the pump cylinder and the discharge seat respectively. During maintenance, the working part of the pump (including the pump shaft, impeller, guide casing and bearing, etc.) can be drawn out without dismantling the water inlet pipeline. The suction and discharge interfaces of the pump can be displaced by various angles such as 180° and 90° to meet the needs of installation.
Performance range:
Flow: 8~2560m3/h
Head: 40~390m
Conveying medium temperature: normal temperature ~ 80 ℃ (special requirements can reach 120 ℃)
