Specialized Tanks, Pumps, & Dosing Systems

Harrington exemplifies its steadfast dedication to the chemical industry through a comprehensive array of solutions, purposefully designed to meet diverse and stringent needs. One of our cornerstone offerings is the Chemical Storage Tanks, thoughtfully engineered to ensure the safe and efficient storage of a wide range of chemicals. These tanks come in various materials, sizes, and configurations, providing reliable and secure solutions for a wide spectrum of chemical storage requirements.

Furthermore, Harrington proudly offers a variety of Chemical Transfer Pumps, skillfully designed to handle diverse chemicals with precision and safety. These pumps are indispensable components for chemical handling applications, ensuring precise and reliable transfer operations. To achieve precise and controlled chemical dosing in industrial processes, Harrington provides Chemical Dosing and Injection Systems. These systems empower operators to achieve accurate measurement and introduction of chemicals, elevating the efficiency and effectiveness of chemical processes to new heights.

Harrington’s dedication to process quality continues with their Chemical Filtration and Straining solutions, which include basket strainers and tee-style filters. These pivotal solutions remove impurities and ensure the purity of chemical products, safeguarding the integrity of chemical processes. We offer chemical-resistant valves, meticulously crafted from durable materials like PVC, CPVC, and PVDF. These valves provide reliable and leak-free control of chemical flow within systems, reinforcing safety and efficiency.

Double Containment Piping

Contamination of the environment do to chemicals leaking from piping systems is a major concern. But there is a solution. Harrington is helping to keep the environment clean and safe by offering field proven double containment piping systems such as: Asahi’s Duo-Pro, Chem-Prolok and Poly-Flo systems, IPEX’s Guardian Double containment and Encase systems, and GF’s Contain-It system. These and other reliable systems for hazardous chemicals are available from Harrington.

Plastic-Lined Steel Piping

When corrosive piping applications require the chemical resistance of plastic and the strength of metal, think plastic-lined-steel piping. It’s available in corrosion resistant PTFE, PFA, Polypropylene, and PVDF locked in liners and pipe sizes to fit your specific needs. Harrington can fabricate spool pieces to your exact specifications.

Victaulic Advanced Groove Systems

Victaulic Advanced Groove Systems deliver a faster, safer, and more efficient approach to joining large-diameter piping in demanding applications. As a proven alternative to welding and flanging, AGS supports easier installation, accommodates system movement, and helps improve long-term reliability across industrial, mechanical, and process piping environments.

Double Wall Containment Mini-Bulk Tanks

Smaller dual-containment tanks provide added safety and environment protection in more confined or remote storage locations. The advanced double wall tank design is enclosed to prohibit foreign matter from entering the secondary containment tank, and a unique octagonal shape provides optimal spacing and sealing surface for the industry’s most reliable transition fitting.

Available in HDLPE and XLPE resin packages
The primary tank is available in both closed and open-top designs.
The secondary tank provides 115-120% of the inner tank’s capacity, complies with CRF-264.193
Transition fitting allows side-safe installation and long-term sealing power through both walls of the tank
The large flat surface area provides ample space for a variety of fitting sizes and styles
Rib reinforced flat top design provides ample surface space for chemical feed pump mounting
Narrow diameter provides location versatility to fit through almost any doorway
Forklift and pallet jack accessible design on 275, 360, and 500-gallon models
Optional top draw tube assembly
The optional vent provides vacuum relief for the interior tank
Optional all-poly elevation stands to create more room for plumbing and other system requirements without using additional floor space

Asahi - Proline Polypropylene Piping

Proline is manufactured from a copolymer polypropylene consisting of propylene and ethylene, according to ASTM D-4101, and contains a stabilizer to resist the effects of corrosive hot liquids.

Pipe and fittings are inventoried in two pressure-rated systems, both designed according to a Standard Dimensional Ratio (SDR). Pressure ratings are derated at higher temperatures
PRO 150 is an SDR11 system rated at 150 psi at ambient temperature
PRO 45 is an SDR32 system rated at 45 psi at ambient temperature
Able to withstand continuous operating temperatures ranging from 32°F to 200°F
Resists most organic and inorganic chemicals, many strong and weak acids, alkalies, organic solvents and some aggressive gases
Well-suited for handling sulfur-based compounds
Corrosion resistance makes it ideal for handling salt water disposal and cooling lines
Joining methods include butt or socket fusion
