Application cases of Albin hose pumps for transporting viscous and crystallizable media

Thread Content

At a power plant in Inner Mongolia operated by Guohua, the desulfurization wastewater treatment chemical dosing system requires the steady addition of substances such as organic sulfur, ferric chloride sulfate, and coagulants into the system. Organic sulfur, ferric sulfate chloride, and the coagulant solution are all relatively viscous liquids that tend to crystallize easily. The customer was previously using a diaphragm pump, and the operating principle and structural characteristics of diaphragm pumps require the presence of check valves at both the inlet and outlet of the pump. Viscous media tend to clog these check valves or cause them to not seal properly, resulting in insufficient pumping power, an inability to achieve the required flow rate, or even a complete failure to pump. Moreover, the internal structure of diaphragm pumps is relatively complex, with many components; the flow channels are not smooth, and crystals tend to form at the right-angle bends or check valves inside. Once crystals form, the pump ceases to function, which directly affects the addition of various materials and prevents the entire desulfurization wastewater treatment system from operating properly. After learning about the various advantages of hose pumps, the customer replaced all the diaphragm pumps in its dosing system with Albin hose pumps. Before the renovation: Maintenance was extensive; there were frequent cases of insufficient dosage of chemicals, or even an inability to apply any chemicals at all. The pumps and related pipelines had to be cleaned frequently, which made it impossible to meet the system’s requirements for chemical addition. After the modification: The 6 hose pumps are operating well, and there have been no more instances of failure to add chemicals due to problems such as blockages or crystallization; maintenance is virtually unnecessary. This not only ensures the proper operation of the entire system but also **reduces maintenance costs and workload. Why do hose pumps have a distinct advantage in transporting viscous and crystalline media? The main reasons are as follows: 1. The medium is transported through a smooth hose, resulting in a smoother flow path. Media with a viscosity of less than 4000 CP can be transported without any issue. For media with a viscosity above 4000 CP, the flow rate per unit time decreases only slightly compared to conventional media, but transportation remains possible. 2. No valves, no seals: The only component in contact with the medium is the inner cavity of the rubber hose; the rotor that compresses the hose is completely separate from the medium, and the medium comes into contact only with the inner wall of the hose. Therefore, hoses made of different materials can be selected depending on the type of medium, making it suitable for transporting most corrosive media. 3. Simple structure and easy maintenance: With fewer components, the likelihood of blockages and crystallization is reduced. Furthermore, if the service life of the hose comes to an end, all maintenance required is simply the replacement of the hose; there are no other vulnerable components. Replacing the hose with a new one is equivalent to replacing the entire pump. Hankun Fluids is the exclusive agent for Albin’s hose pump products from France.
