Acid Transfer Pumps

Acid Transfer Pumps

For industrial acid transfer applications, this metering pump delivers highly precise acid dosing.acid transfer pump Designed for automated dosing systems, the pump provides high metering accuracy and excellent corrosion resistance to safely handle corrosive acids like hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, and acetic acid. The pump has a compact, base-mounted design that allows easy installation in diverse industrial settings. Its mechanical seals prevent leaks and ensure safe operation, while its manual controls enable user-friendly operations.

This acid transfer pump is ideal for use in industries such as manufacturing, chemical water treatment, electroplating, mining and metallurgy, and pharmaceuticals. The chemical handling processes in these sectors involve significant hazards, and proper equipment selection can help ensure worker safety and prevent costly accidents such as pipeline corrosion or equipment leakage.

The acid transfer pumps in this article are suited to the safe transfer of low- to medium-concentration corrosive acids with a liquid density of up to 1.9 g/cm and viscosity up to 100 cP. They feature a corrosion-resistant stainless steel casing and other materials, which protect the pump from damage by acids. They have a mechanical seal with various options including PTFE, glass fiber reinforced polypropylene (GFRPP), carbon fiber reinforced polypropylene (CFRPP), or chlorotrifluoroethylene (CFETFE). Using a suitable face material for the pump’s mechanical seal helps protect the mechanical sealing surfaces against erosion by acid-laden media.

An acid transfer pump eliminates the dangerous task of lifting or tilting drums and carboys while transferring fluids. The pump has a built-in mechanical or pneumatic driven diaphragm that physically displaces the media while check valves direct flow for accurate dosing. The acid pump can be used for both positive and negative pressure suction with a choice of discharge adapters that fit common acid storage containers. It is self-priming and can run dry without a power source (AODD versions are UL Listed for use in potentially explosive environments).

When selecting an acid pump, users should consider the type and concentration of the process fluid as well as operating temperature and any contamination. Understanding these factors improves the matching of pump design and materials to application requirements. Cross-referencing information from acid resistance charts and the manufacturer’s material database is helpful. For example, abrasive acids typically require a more durable and rugged mechanical seal than non-abrasive acids. This will reduce the frequency of mechanical seal replacements and improve operational reliability. The same holds true for other system components, such as abrasion-resistant hoses and gaskets. Regular maintenance should include checking for leaks, cleaning the mechanical seal, and ensuring the motor protection is effective to prevent ingress of dirt and dust. For optimal operation, the pump should be serviced every three to six months, depending on usage intensity. A qualified technician can perform these services, removing the pump from service, detaching it from its power supply, and reassembling, testing, and re-sealing. This routine maintenance minimizes downtime and keeps the acid pump running at peak performance.
