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.

We are experts in one-stop pumping solutions, and durability is always the most cost-effective solution for your demanding applications. Next, I will take you to know about our centrifugal horizontal split pump for fire protection.
The horizontal split case pump is named after the split design of the casting, in which the cover can be lifted from the pump to expose the internal components (impeller, shaft, double suction seal, bushings, bearings, etc.) for easy access to all working parts; the impeller of the split casing pump has two water inlet points, which is where the term "double suction" is used, so the horizontal split case centrifugal pump is also called a single stage double suction centrifugal pump.
Horizontal split pumps are the most common type of fire pump, and these pumps are designed and tested for fire protection applications where performance reliability is critical. The pump body and cover form the working chamber for the impeller. The inlet and outlet flanges have pipeline screw holes for installing vacuum gauges and pressure gauges, and the lower part of the inlet and outlet flanges have pipeline screw holes for the static balance verification of the discharge impeller. Both sides are fixed with sleeves and sleeve nuts. Its axial position can be adjusted by a sleeve nut. The axial force of the impeller is balanced by the symmetrical arrangement of its vanes The horizontal split centrifugal pump shaft is supported by two single-row radial ball bearings. The bearings are installed in the bearing bodies at both ends of the pump body and lubricated with grease. The shaft seal is a soft packing seal. To cool and lubricate the seal cavity and prevent air leakage into the pump, there is a water seal ring between the packings. When the horizontal split centrifugal pump is working, a small amount of high-pressure water flows into the packing cavity through the water seal pipe, which acts as a water seal. Horizontal split centrifugal pumps are designed with suction and discharge nozzles in the lower half of the housing, side by side, while the impeller shaft is located between two bearings, one on each side. This robust and simple design is particularly suitable for high flow applications as it reduces thrust loads and allows operation over a wide range of capacities. The durability of the split pump design allows the pump to be used for water flows in excess of 5,000 GPM.
In order to meet the strict fire protection requirements, the split pump is usually made of ductile iron pump casing with 304 or 316 stainless steel wetted parts, duplex stainless steel wetted parts, nickel aluminum bronze wetted parts or special materials can be provided on request
An Pump Machinery's split case fire pumps are available in flow rates from 500 GPM to 5000 GPM, are available with electric (50 Hz and 60 Hz) or diesel drive, and are designed to meet most normal requirements.
Horizontal split case pumps are generally heavier and more expensive than comparable end suction pumps with lower initial costs due to the need for large flanges, larger impellers and overall large size for split housing seal joints and also require more installation space. However, the maintenance costs and downtime of the end suction pump can far outweigh any initial cost savings.
The horizontal split pump is easy to maintain because the upper part of the pump body can be disassembled, so the internal parts (bearings, shafts, impellers, etc.) are exposed and will not interfere with the suction or discharge piping, and will not move the motor.
On the other hand, end suction pumps are more difficult to maintain due to their compact design, for example, removing the impeller requires removing the motor to provide room to pull the impeller back into the housing.
The orientation of the split-type fire pump must be determined at the time of manufacture and installation. The pump must be right-handed (clockwise) or left-handed (counterclockwise) from the driver's vantage point. For diesel-powered fire pumps, the pump can only rotate clockwise. Failure to install properly may result in the pump being disassembled and reassembled in the field for proper rotation (if driven by an electric motor) or rerouting of piping (if driven by a diesel engine).
The precise balance of all factors in the design of An Pump Machinery's horizontal split fire pump provides mechanical reliability, efficient operation, and minimal maintenance. The simplicity of the design ensures long effective unit life, reduced maintenance costs, and the lowest power consumption, widely used in fire protection of buildings and other building infrastructures such as industrial fire protection systems, residential fire protection systems, commercial fire protection systems, warehouses Fire-fighting system, fire-fighting on ships and offshore platforms.
