LIQUIDYNAMICS INC.

Liquidynamics Inc. is a manufacturer of fluid handling equipment, with a primary focus on dispensing pumps and systems for diesel exhaust fluid (DEF) and other industrial fluids. The company's product line includes air-operated and electric drum pumps, tote-mount and drum-mount dispensing systems, suction tubes, discharge hose kits, dispense couplers, and replacement filters. These products are designed for use in applications such as DEF dispensing, fuel transfer, and general fluid handling in industrial, automotive, and fleet maintenance environments. Liquidynamics equipment is built to handle a range of viscosities, with air-operated piston pumps rated for up to 14,000 cps and electric pumps offering flow rates up to 8 gpm. Construction materials include steel, polypropylene, HDPE, and EPDM, selected for compatibility with DEF and other fluids. The pumps operate on standard AC or DC voltages (115 V AC, 12 V DC) and are available with or without meters, nozzles, and hose reels. 3G Electric stocks a range of Liquidynamics products, including complete pump systems and individual components such as suction tubes and hose kits, supporting maintenance and replacement needs for global customers. The product range covers fixed-length suction tubes for 330-gallon totes, filtered vents with RSV couplers, and discharge hose kits with EPDM tubing rated for temperatures from 17°F to 104°F. Liquidynamics components are designed for integration with existing drum and tote dispensing setups, with specifications such as 3/4 in FNPT and 2 in FNPT connections. The brand's focus on DEF-specific equipment aligns with the growing demand for selective catalytic reduction (SCR) systems in diesel engines, where precise fluid handling is required. 3G Electric provides access to these products with logistics support for international orders, enabling procurement specialists and maintenance managers to source replacement parts or complete systems for their operations.

Frequently asked questions

Common questions about LIQUIDYNAMICS INC. from 3G Electric.

What types of fluids can Liquidynamics drum pumps handle?

Liquidynamics drum pumps are designed primarily for diesel exhaust fluid (DEF) and other non-corrosive industrial fluids. The air-operated piston drum pump (MPN 21100-S7) handles viscosities up to 14,000 cps, making it suitable for thicker fluids. Electric drum pumps (e.g., MPN DT15H20XAPXXRSV) are rated for 8 gpm flow and use polypropylene construction, which is compatible with DEF. Always verify material compatibility with your specific fluid, as components like steel suction tubes and EPDM hoses are selected for DEF but may not suit aggressive chemicals.

Are Liquidynamics DEF dispensing pump systems available with digital meters?

Yes, several Liquidynamics DEF dispensing pump systems include digital meters. For example, the tote-mount system (MPN 970027-02AG) and the drum-mount system (MPN 33115-S2AG) both come with digital meters as part of the kit. These systems also include a stainless steel nozzle and discharge hose. If you need a system without a meter, the drum-mount system (MPN DT15H20XAPXXRSV) is available as a pump with discharge hose and nozzle only.

What is the maximum flow rate of Liquidynamics electric drum pumps?

Liquidynamics electric drum pumps, such as those in the DT15H20XAPXXRSV and 970027-02AG models, have a maximum flow rate of 8 gpm. This applies to both 115 V AC and 12 V DC versions. The air-operated piston drum pump (MPN 21100-S7) has a lower maximum flow rate of 4 gpm but can handle higher viscosity fluids. Flow rates may vary depending on fluid viscosity and head pressure.

What materials are used in Liquidynamics suction tubes for DEF transfer pumps?

Liquidynamics suction tubes for DEF transfer pumps, such as the fixed-length tube (MPN 195206-46), are constructed from HDPE (high-density polyethylene). This material is chosen for its chemical resistance to DEF and durability. The tube is designed for use with 330-gallon totes and has a fixed length of 46 inches. It is compatible with Liquidynamics pump models like the 195206B.

Can Liquidynamics discharge hose kits be used with other pump brands?

Liquidynamics discharge hose kits, such as the 950390-12M, are designed with standard 3/4 in FNPT and 2 in FNPT connections, which are common in industrial fluid handling. While they are intended for use with Liquidynamics pumps, the threaded connections may allow compatibility with other brands that use the same port sizes. The hose is 12 feet long with EPDM tube material, rated for temperatures from 17°F to 104°F. Verify thread compatibility and fluid compatibility before use.

What is the purpose of the Liquidynamics filtered vent (MPN 950392)?

The Liquidynamics filtered vent (MPN 950392) is a dispense coupler accessory used in DEF dispensing systems. It includes an RSV coupler and a filtered vent to allow air to enter the container as fluid is dispensed, preventing vacuum lock while filtering out contaminants. It is compatible with manufacturer model number 950390-12M and is typically used on drums or totes to maintain smooth flow during dispensing.
