About LIQUIDYNAMICS INC.

Liquidynamics Inc. is a manufacturer of fluid transfer and dispensing equipment, with a product line that includes drum pumps, DEF (Diesel Exhaust Fluid) handling components, and related accessories. The company's catalog covers both electric and manual pump options, as well as a range of couplers, valves, and hose kits designed for industrial and commercial fluid management. Liquidynamics products are commonly found in applications such as automotive service, fleet maintenance, agricultural operations, and industrial manufacturing where precise fluid dispensing and contamination control are required.

The product families supplied by 3G Electric include discharge hose kits, dispense couplers, container valves, and drum valves, all specifically engineered for DEF and other fluid transfer systems. These components are constructed from materials selected for chemical compatibility and durability: EPDM hoses and seals resist degradation from DEF and other fluids, while stainless steel and HDPE bodies provide corrosion resistance and structural integrity. For example, the discharge hose kits (MPNs 950390-25M and 950390-12M) feature EPDM tubes with 3/4 in FNPT and 2 in FNPT connections, rated for temperatures from 17°F to 104°F. Dispense couplers such as SKU 48GP49 and 49CD13 use stainless steel bodies with EPDM seals and are available with hose barb or MNPT connections. Container valves include polyethylene and HDPE options, as well as stainless steel models with buttress connections and downtubes in various lengths to accommodate different drum sizes.

3G Electric supports the Liquidynamics line by stocking a focused selection of these DEF transfer and dispensing components, providing technical specifications, and facilitating global procurement. The product range addresses key points in a fluid transfer system: from drum or container connection (valves), through transfer (hose kits and pumps), to final dispensing (couplers). This allows maintenance and procurement teams to source compatible components from a single supplier. The emphasis on material compatibility—EPDM, stainless steel, HDPE, and polyethylene—reflects the requirements of handling DEF, which is corrosive to many common materials. The temperature ratings and connection sizes are clearly specified, enabling engineers to verify fit and function before purchase. 3G Electric serves a global customer base, shipping these components to industrial, automotive, and agricultural operations worldwide.

Common Applications

  • Automotive service — Liquidynamics DEF dispense couplers (SKU 48GP49, 49CD13) for dispensing DEF into vehicle tanks.
  • Fleet maintenance — Liquidynamics drum valves (MPN 195205B, 195206B) for connecting DEF drums to transfer systems.
  • Agricultural equipment — Liquidynamics discharge hose kits (MPN 950390-25M) for transferring DEF from drums to tractors.
  • Industrial manufacturing — Liquidynamics filtered vent (MPN 950392) for contamination control in DEF dispensing.
  • Heavy-duty trucking — Liquidynamics container valves (MPN 195205N) for DEF storage and dispensing in maintenance bays.

Frequently asked questions

Common questions about LIQUIDYNAMICS INC. from 3G Electric.

What materials are used in Liquidynamics DEF dispense couplers?

Liquidynamics DEF dispense couplers are available with stainless steel bodies and EPDM seals. For example, SKU 48GP49 features a stainless steel body, a 3/4 in hose barb connection, and a 0° outlet angle. SKU 49CD13 has a stainless steel body with a 1 in MNPT male connection and a 0° outlet angle. The EPDM seals are chosen for compatibility with DEF, which can degrade other elastomers. These couplers are designed for use in DEF transfer systems and are compatible with specific manufacturer model numbers, such as 33296-S3 for SKU 49CD13.

What is the temperature range for Liquidynamics discharge hose kits?

Liquidynamics discharge hose kits, such as MPN 950390-25M and 950390-12M, are rated for a temperature range of 17°F to 104°F. These kits feature EPDM hose tubes with 3/4 in FNPT and 2 in FNPT connections. The EPDM material provides resistance to DEF and other fluids within this temperature range. The hose length options include 12 ft and 25 ft, allowing flexibility in routing from drum pumps to dispensing points. These kits are typically used as accessories for drum pumps to transfer fluids from drums or containers.

What types of container valves does Liquidynamics offer for DEF?

Liquidynamics offers container valves for DEF in several configurations. The polyethylene body valve (MPN 195205N) is compatible with model 195205C. The HDPE drum valve (MPN 195206B) features a 2 in buttress connection and EPDM seal, with downtube lengths of 35, 39, or 47 inches. The stainless steel drum valve (MPN 195205B) has a 2 1/2 in buttress connection and downtube lengths of 32, 40, or 46 inches. These valves are designed to fit standard drum openings and provide a secure connection for DEF transfer. Material selection depends on chemical compatibility and durability requirements.

How do I select the correct Liquidynamics dispense coupler for my DEF system?

Selection depends on the connection type and size required. Liquidynamics dispense couplers are available with hose barb or MNPT connections. For example, SKU 48GP49 has a 3/4 in hose barb, while SKU 49CD13 has a 1 in MNPT. The outlet angle is 0° for both. Check compatibility with your existing equipment: SKU 48GP49 is compatible with model 195205D, and SKU 49CD13 with model 33296-S3. Also consider the filtered vent option (MPN 950392), which includes an RSV coupler and is compatible with model 950390-12M. Always verify material compatibility with DEF and system pressure ratings.

What is the purpose of the Liquidynamics filtered vent for DEF?

The Liquidynamics filtered vent (MPN 950392) is used as a dispense coupler in DEF systems. It includes an RSV coupler and is compatible with manufacturer model number 950390-12M. The filtered vent allows air to enter the container as fluid is dispensed, preventing vacuum formation, while filtering incoming air to prevent contamination of the DEF. This helps maintain fluid quality and ensures smooth dispensing. It is constructed with materials suitable for DEF exposure. This component is typically used in conjunction with drum pumps and discharge hose kits to complete a DEF transfer system.
