Hose compensators are designed to absorb vibrations and noise transmitted between pumps, tanks (wells), and associated equipment. They also ensure smooth flow transition between pipelines and the suction and discharge connections of slurry pumps, using both eccentric and concentric reducer configurations.
Matching internal diameters is critically important for long-term performance and reliability. Combined with abrasion-resistant rubber compounds, this ensures best-in-class performance at the lowest possible cost. This is achieved by using the highest-quality natural rubber and processing it with advanced manufacturing technologies.
Hose compensators are manufactured to order, in specified lengths, with integrated flange options that allow direct bolting to pump suction or discharge flange surfaces. Every aspect of standard compensator hose construction can be customized to suit specific operating conditions, including internal diameter, length, working pressure, as well as the material and thickness of the abrasion-resistant inner lining.
