HLB, HLBK, HLKS and HLKT vertical diagonal flow pumps are produced in our plants since 1984, mainly used for supply of clear water, rain water, sea water and sewage at a temperature lower than 60℃. The pumps can be used as circulation pumps in power plants, or applied for industrial water supply (in iron and steel plants and wharfs), city water supply system, water exhaust engineering and farmland irrigation and drainage.

Structural Features
1、Installation Methods
Single-layer foundation: the electrical motor and pump are directly installed on one foundation, with the pump exhaust port set above or below the function layer.
Double-layer foundation: the electrical motor and pump are installed on their own foundations, with the pump exhaust port set between the two layers of foundations.
2、The pump has three types, namely, unwithdrawable type, rotator (including guide blades) withdrawable type and whole inner pump body withdrawable type.
3、Pump impellers have three types also, namely, open impeller type, enclosed impeller type and blade-adjustable impeller type.
4、Pump axial forces are released by thrust bearings of the electrical motor or pump itself.
5、Pump bearings can be separated into rubber (wear-proof, anticorrosion, sea water corrosion resistance rubber) guide bearing, PEEK bearing, PPEK bearing and Salong bearing. Normally, pump shafts have protective sleeves, in which are full of clean pressure water for guided bearings lubrication and washing, with water quantity controlled by flow relay to avoid bearings damaged due to insufficient water. When pumps are used to convey sewage or water contains grains, the end of guided bearings inside the guide blades has a stop automatic shaft seal device to prevent mediums leaking into the bearings after pump is stopped.
6、Pumps used to convey sea water shall be made of sea water corrosion resistant materials, and equipped with sacrificial anode and external power cathodic protection devices, so as to prevent electrochemical corrosion to pump parts.
7、The pump and electrical motor are coupled directly, with reduction gear box assembled additionally.
8、The pump suction port is horn-shaped or elbow-shaped interval channel.
