1. Overview

Our LP-type long-shaft vertical drainage pump is mainly used for pumping sewage or wastewater that is non-corrosive, has a temperature below 60°C, and contains suspended solids (excluding fibers and non-abrasive particles) at a concentration of less than 150mg/L.

The LP-type long-shaft vertical drainage pump is an enhanced version of the LP-type, featuring an added shaft-protecting sleeve through which lubricating water flows. It can pump sewage or wastewater with a temperature below 60°C and containing certain solid particles (such as iron filings, fine sand, coal dust, etc.).

2. Applications

It is widely used in municipal engineering, metallurgy and steel production, mining, chemical and paper industries, water supply, power plants, farmland water conservancy projects, and other fields, suitable for various scenarios requiring efficient drainage.

3. Characteristics   

● Applicable media and performance range:The LP-type long-shaft vertical drainage pump is suitable for pumping sewage or wastewater that is non-corrosive, has a temperature below 60°C, and contains suspended solids (excluding fibers and non-abrasive particles) at a concentration of less than 150mg/L.

● Structural Characteristics: The vertical structure is adopted, which can effectively save installation space. It features a compact design, convenient installation, high reliability, and operational efficiency.‌

● Transmission Device: The transmission device includes thrust bearings capable of effectively withstanding both axial and radial forces generated during pump operation. The shaft seal adopts a combination of a skeleton oil seal and a felt oil seal to ensure stable operation of the transmission device.

• 1.LP-type vertical long-shaft sewage pump is mainly used for which scenarios?

  • LP type vertical long-shaft sewage pump is mainly used for pumping non-corrosive, temperature below 60℃, wastewater or sewage with suspended solids (excluding fibers and non-abrasives) content less than 150mg/L. It is widely applied in municipal engineering, metallurgy and steel, mining, chemical and papermaking, waterworks, power plants, and farmland water conservancy projects.

• What are the structural characteristics of the LP(T) type vertical discharge pump?

  • The structural characteristics of the LP(T) type vertical discharge pump mainly include vertical installation, compact structure, small floor space, the pump shaft extending vertically upward, the impeller located below the liquid surface, and the inlet and outlet on the same horizontal line. This design makes the pump more stable during operation and easier to maintain and service.

• If a fault occurs during the operation of an LP(T) type vertical discharge pump, how should it be handled?

  • During operation, if an LP(T) type vertical discharge pump fails, the machine should be stopped for inspection first, and then the fault should be diagnosed and handled according to the symptoms. Common faults include motor overheating, bearing damage, seal leakage, etc. For motor overheating, check if the motor wiring is loose, if the motor is overloaded, etc.; for bearing damage, check if the bearing lubrication is good, if the bearing is worn, etc.; for seal leakage, check if the seal is aged, if the installation is correct, etc. Take corresponding repair measures based on the cause of the fault to ensure that the pump can return to normal operation.
