Sand suction rubber hose is a kind of our wear resistant rubber hoses, which is widely used to absorb impurities such as silt, sand and gravel. Sand suction rubber hose named according to its usage, due to its wide range of applications, such as river dredging, mining, construction engineering, etc., the sand suction rubber hose plays an important role in all many industries.

When the rubber expansion joint is susceptible to large stretching, vibration, torsion or lateral movement during use, sometimes it is necessary to add limiters(tie rods) to ensure the normal operation of the joint to extend its service life.

As a pipe connection device, the bellows expansion joint can reduce vibration and noise in the pipe system, and can absorb the thermal expansion and contraction which caused by temperature changes and other factors. However, in some special cases, the metal expansion joint needs to be used together with the inner sleeve to achieve better results.

The flotation machine is an indispensable equipment in mineral processing, and the impeller( also called rotor) and cover plate( also called stator) are the core components.Polyurethane rotors and stators also our product which belong to our polyurethane product.

During the water treatment process in chemical plants, pipeline systems often need to withstand the impact of water flow, temperature changes, media corrosion, foundation settlement and other factors. These factors may cause vibration, displacement and deformation of the pipeline system, thereby affecting the stability and efficiency of water treatment. Therefore, a connection that can absorb these vibrations, displacements and deformations is needed to ensure the stable operation of the water treatment system.Expansion joints will be needed in this system, rubber expansion joints have fo...

Dismantling joint just one kind of Hesper’s expansion joints, it’s one of our main products. Rigid dismantling joint and non-rigid dismantling joint are two common connection devices.In last news we know how to distinguish them from the appearance, except from the appearance, they also have following differences:

In the engineering field, dismantling joints play a vital role. They not only affect the stability and safety of the pipeline system, but also directly affect the operating efficiency and life of the equipment. Among them, rigid(or thrust) dismantling joint and non-rigid( or non-thrust) dismantling joint are two common connection devices, they also two main types of our dismantling joints. Just from the appearance, although they looked very similar, but also have differences.

Wear-resistant rubber hose is a high-performance hose widely used in various industrial fields,its core function is to transport various medium. From the perspective of product structure, wear-resistant rubber hoses are usually composed of inner rubber layer, reinforcement layer and outer rubber layer. 

Selecting the right polyurethane screen panels is crucial for achieving optimal performance and longevity in screening applications. These panels are widely used in mining, quarrying, and other industries where materials need to be separated based on size. This article provides a comprehensive guide on how to choose the right polyurethane screen panels for your needs.
