Imagine using a toaster to make soup. Similar results occur if the wrong type of pump is used to transfer acidic solutions. Acids are typically highly corrosive substances that can be dangerously reactive when exposed to certain other elements or conditions. Due to these risks, it is critical to choose the appropriate materials and design when selecting a pump for acid applications.
Acid pumps are constructed of materials that can withstand exposure to acidic solutions. They are carefully designed to safely contain high-risk substances, to protect workers and the environment. These durable pumps can be found in multiple applications, transferring acids for chemical processing, plating, wastewater treatment, and a host of other industries. They are available in a variety of types to suit each of these distinct applications.
The diversity of acid pump applications cannot be served by one type of pump. Four main styles of acid pumps meet the demands of the full range of acid transfer needs across various industries.
Operation: A motor-driven shaft is attached to the motor on one end and the impeller on the other. Where the shaft enters the pump's wet end, a mechanical seal prevents fluid from moving beyond the casing.
Benefits: These pumps are often ideal for applications that require the transfer of liquids that contain solids. They also typically offer a lower price point compared to sealless mag-drive pumps.
Applications: Common applications for a sealed acid pump include chemical processing, printed circuit boards, pharmaceutical, and wastewater treatment. .
Operation: A sealless acid pump features powerful magnets that eliminate the need for a seal. The magnets are located on the impeller and on the outer drive magnet attached to the motor shaft. As the drive shaft rotates, it causes the impeller to rotate. As acids pass through the pump, they remain hermetically sealed within the housing.
Benefits: Because the pump has no seal, the seal can never leak. This also eliminates the need for replacement seals, which reduces the cost of parts and labor over the life of the pump.
Applications: Common applications include chemical processing, plating, electronics, pharmaceuticals, rail cars, biodiesel, mining, agriculture, and wastewater.
Operation: In vertical acid pump design, the impeller is mounted perpendicularly on a vertical rotating shaft. The motor turns the pump impeller, rotating the liquid. This creates pressure, which allows the liquid to be pumped vertically.
Benefits: The main benefit of a vertical acid pump is a smaller footprint. A vertical acid pump takes up less floor space for applications with limited surface area. Many vertical acid pumps are manufactured from corrosion resistant materials and are capable of having the pump body immersed in the liquid.
Applications: Common applications for a vertical acid pump include wastewater, pharmaceutical, and chemical transfers.
Operation: A drum pump features a narrow tube that fits into the opening of a drum. A small motor is attached to the shaft. The pump transfers liquids from the drum to a receiving container.
Benefits: Drum pumps eliminate the need to tip or pour liquid from drums, which can pose hazards. Drum pumps also offer portability.
Applications: Common applications include water treatment chemicals, cleaners, plating solutions, kidney dialysis solutions, DEF, coolants, and solvents.
