Sand pumping hose
Structure:
Inner layer: black wear-resistant synthetic rubber
Skeleton layer: multi-layer synthetic fabric layer + spiral wire layer
Outer layer: black oil resistant synthetic rubber
Use:
It is suitable for extracting solid or granular materials such as mineral sand, river sand, coal dust and cereal (inina, wheat, corn)
Features:
The rubber hose has good bending properties, the inner rubber has good elasticity and wear resistance, and the outer rubber has good aging resistance and wear resistance. With the dual performance of positive pressure and negative pressure, under the normal use of -80kpa (600mm Hg) vacuum conditions, the hose bursting pressure is not less than three times the working pressure.
