Chemical pumps are often used when the chemicals that need to be transferred are corrosive or abrasive, and they are more durable than traditional pumps.
Chemical pumps are designed to pump various aggressive liquids (pumping chemicals: acids, bases), so their main fields of application are in the chemical and petrochemical industries (pumping sulfuric acid, acetic acid, phosphoric acid, sulfuric acid, hydrochloric acid, CIP fluids, Corrosive dyes, radioactive fluids, sodium hypochlorite nitrate, caustic solutions, ferric chloride, oil products).
You will find that chemical pumps generally come in two different types; centrifugal pumps or positive displacement pumps (screw, diaphragm or plunger), today we are mainly talking about centrifugal chemical pumps.
An Pump Machinery has been a supplier of chemical centrifugal pumps for many years, and we know that having the right solution for your chemical process is critical. Pumps that are not compatible with your chemicals can swell, dissolve or become brittle, eventually leading to leaks and failures. This is why special consideration needs to be given to the material of the chemical transfer pump as well as the temperature and concentration of the fluid being processed.
To ensure that the chemical transfer pump we choose will provide you with long, trouble-free service life, we will require complete fluid conditions such as temperature, concentration, pH, etc. The nature of the pumped fluid means that chemical pumps are made entirely of chemically resistant polymers. Commonly used metal chemical centrifugal pump materials are ss316 ss316L Duplex stainless steel, plastic chemical centrifugal pump materials are Fluoroplastic, PTFE, etc.
Centrifugal chemical pumps are made of corrosion-resistant materials. Their construction allows them to withstand the harshest chemicals and conditions inside and out. These pumps allow chemical manufacturers, distributors and users to transfer a wide variety of fluids under varying conditions—even those that would quickly damage other pumps. Second, the pump has a long service life. Even when used to transport highly corrosive chemicals, the pump can withstand these conditions and improve return on investment.
Centrifugal chemical pumps are a good choice for pumps that work when needed. Their durable designs have stood the test of time. This type of fluid transfer pump is the solution of choice for a wide range of industries. These pumps provide consistent, long-lasting performance.
Compared to other pumping technologies, centrifugal chemical pumps are ranked highly in terms of energy efficiency. This gives them a significant advantage over other pump styles. Their efficiency reduces both short-term and per-unit life-cycle costs. This efficient operation also reduces stress on the energy system. This is critical in environments where multiple pumps and other machinery need to be operated simultaneously.
Pumps with a long service life are less attractive if frequent routine maintenance is required. Fortunately, centrifugal chemical pumps have low daily maintenance requirements. Their simple and efficient design minimizes the number of parts that need attention or replacement. This low-maintenance design, therefore, reduces repair costs and downtime.
Before starting the chemical pump, the suction line and pump must be filled with liquid. After the pump is turned on, the impeller rotates at high speed, and the liquid rotates with the blades. Under the action of centrifugal force, it flies away from the impeller and sprays out. The injection speed in the diffusion chamber of the pump casing gradually slows down, and the pressure gradually increases. Outlet, outlet pipe. At this point, in the center of the vane, the liquid is thrown around so that neither air nor liquid creates a vacuum depression. The liquid in the liquid pool flows into the pump through the suction pipe under the action of atmospheric pressure. It is constantly being sucked out of the cistern and continuously drained out of the drain.
First of all, determine the material and sealing material of the chemical pump by clarifying the temperature and PH value of the medium to be transported and the medium. Otherwise, because the pump body or sealing material cannot withstand the corrosion of the liquid, it will cause delays in chemical production and unnecessary economic losses.
Secondly, the flow and head of the chemical pump are required. The chemical pump purchaser should know the height, distance, and a number of elbow valves of the chemical pump when selecting the model, and accurately inform the chemical pump manufacturer.
Finally, be sure to confirm the density, viscosity, and particle impurities of the medium conveyed by the chemical pump. If there are particles, a corrosion-resistant slurry pump will be used.
