Product Description
 
LDTN, LDTNA and LDTNB pumps are all vertical cylinder or bag structures. The pump suction and exhaust ports are set on pump cylinder and exhaust seats respectively. The pump’s working parts (including pump shaft, impellers, diversion case and bearings) can be moved out easily in maintenance, without disassembling water suction pipes. Pump suction and exhaust ports can be adjusted to different angles such as 180°and 90°to meet different installation needs.

The pump cylinder is designed of vacuum structure and closed impellers, of which the first-level impeller has two types of single-suction and double-suction designs. The pump case has replaceable wearing rings, which has a strong anti-interlocking force. The pump also has several water-lubricated bearings for middle support of rotator radial forces. Normally, the rotator radial forces are balanced by adding balance mechanism and thrust bearing to pump itself. Pump rotator shafts are interconnected by cylinder snap ring couplings. Rotators have good concentricity. The pump and electrical motor are connected by flanged elastic pin couplings. Shaft seals are normally mechanical seals, or soft packing seals upon customers' needs.

Notes for Numbers


Product Manufacturing Process

The outer cylinder, pump seat, support seat and electrical motor brackets of the condensate removal pump are made of carbon steels by welding;
pump suction pipes and diversion case is made of cast iron;
pump impellers are made of cast steel;
pump shaft is made of forged parts
 
Product Features:

The condensate removal pump made by our company has its own intellectual property rights. The pump has first-level impellers of high cavitation resistance and secondary-level impellers of high efficiency. Its axial thrust is released by a pump balance mechanism and thrust bearing but not the electrical motor. Therefore, the electrical motor can be designed with lighter weight and improved reliability. The thrust bearing is lubricated by thin oil, and it can suck lubricating oils by itself, this it doesn't need external oil stations and saves space. The radial bearings are guide bearings with a water lubrication system, which means it can use its own mediums for lubrication and doesn't need lubricating oils supplied externally.
