Product Introduction
DYLK, DYLB type vertical long-axis pump is suitable for power plants, steel mills, water companies, sewage treatment plants, petrochemical, mining and other industrial and mining enterprises, as well as municipal water supply and drainage projects, agricultural irrigation, flood control and drainage projects. It can be used to transport clean water, rain water, iron pit water, sewage and sea water and other media below 55℃, with a flow range of 30-7000m. /h, lift range 7-200m. The temperature of the specially designed conveying medium can reach 90℃.
Product Features
● Stable operation, safe and reliable, vacuum free starting, long service life cycle.
● Pump volume is small, the base covers less area, the pump length below the base can be adjusted, and the adaptability is strong.
● Simple and reliable flow channel, saving pump house infrastructure investment.
● Reasonable structure, convenient installation and disassembly, easy maintenance and repair.
● High pump efficiency, reduce operating costs.

Product Structure Description
DYLK, DYLB type pumps are vertical single-stage (multistage) centrifugal or oblique flow with guide vane structure.
The structure of the pump has the pump outlet above and below the installation base (type codes are S and X, respectively), the pump to bear axial force and the motor to bear axial force (type codes are T and D, respectively), the external lubricating water and the pump itself lubrication.
The pump installation type is wet pit installation or dry pit installation.
Wet pit installation: the lower part of the pump is immersed in the suction pool.
Dry pit installation: the pump uses pipeline water, and 90° is used between the pump suction horn and the water inlet pipe; Elbow inlet bend connection.
Pump bearings are rubber guide bearings or Cylon guide bearings.
When the pump diameter is below 1000mm, the pump rotor is generally not pumped; The axial water thrust and rotor weight of the pump are generally borne by the thrust bearing of the pump body, and the elastic connection between the pump and the motor is adopted. The pump outlet is located on the base of the mounting surface (structural form of type code ST). If required, the motor can also bear the axial water thrust and rotor weight; Or a combination of other structural forms (type code SD, XT, XD); If the user has the requirement, it can also be designed into a withdrawable structural form. When the pump diameter is more than 1000mm, the pump rotor is generally pumpable; The axial water thrust and rotor weight of the pump are generally borne by the motor thrust bearing, and the pump and motor are rigid-connected. The pump outlet is located under the base of the mounting face (type code XD). If required, the pump can also bear the axial water thrust and rotor weight; Or a combination of other structural forms (type code XT, SD, ST). If required by the user, it can also be designed into a non-withdrawable structure.
When the pump body is subjected to axial water thrust and rotor weight, the pump thrust bearing is lubricated with thin oil, and the thrust bearing component is equipped with Pt100 temperature measuring element to measure the bearing temperature or pressure thermometer to measure the lubricating oil temperature.
Pump axial seal adopts packing seal.
The clearance between the impeller and the impeller chamber (rotating part and stationary part) can be adjusted on the basis of the pump installation, and the operation is convenient.
Looking at the pump from the direction of discharge, the motor junction box and the external lubricating water nozzle of the pump are located on the left. Can also be arranged in other directions according to user requirements.
