The Heshan brand CLB series asphalt pump is mainly used for suction, pumping, and coating high-temperature asphalt. It is most suitable for asphalt coating operations in construction projects such as highways, bridges, roads, and squares. It can also be used for suctioning and pumping other liquid media with high viscosity, such as various mechanical oils, hydraulic oils, heavy oils, residual oils, various vegetable oils, etc.

Product Features

The CLB type asphalt pump is a rotary type, mainly composed of a pump body, a base, a driving gear, a driven gear, and a safety valve body.

The active shaft is supported by an additional oil containing sleeve and lubricated with HG-24 saturated cylinder oil through an oil cup. Both sides of the asphalt pump are equipped with connecting heads with conical pipe threads for connecting the inlet pipeline position, and the conical pin is made with internal threads for easy disassembly. The sealing paper pad is also used to adjust the axial clearance of the gear, which is specified as a one-way clearance between 0.05-0.08mm.

There are four holes in the lower part of the machine base for installation and use

The asphalt pump is equipped with a safety valve, which has been set to a working pressure of 1-+0.05Mpa and sealed with lead at the factory. During operation, the medium enters the suction chamber and is pressed into the discharge chamber and flows out through the rotation of the gear. Adjusting the handwheel can change the output flow rate. When the handwheel is rotated to the right, the safety valve is pushed open, and the pump loses output pressure and stops discharging; When the handwheel is rotated to the left, the safety valve will resume its function and the medium will output normally.
