• Marquest Scientific LG-WDR-F2 Natural Polypropylene Recirculating Lab Gooseneck Faucet: Engineered for Purity and Performance
• The LG-WDR-F2 is a specific configuration of Marquest Scientific's Recirculating Lab Gooseneck Faucet, designed for wall-mount applications in high purity environments.
• This model features a Duraline control valve, a recirculating control module with 3/8" female NPT inlet x outlet, and a handle positioned in front.
• The faucet is constructed from natural polypropylene, ensuring compatibility with high purity liquids such as Type I, II Deionized, RO, and Ultra Filtered Water.
• Recirculation System The LG-WDR-F2 incorporates a recirculation system that reduces bacterial growth and other biological impurities caused by stagnation.
• By providing continuous liquid motion during all phases of operation, this faucet helps maintain a high level of purity and performance.
• Construction for High Purity Environments The LG-WDR-F2 is constructed with an all-virgin natural polypropylene wetted fluid path and PTFE seals
• making it suitable for use in high purity environments. No elastomers, metals, or lubricants are used in the construction, ensuring the highest level of purity.
• The heavy wall construction and smooth internal flow path contribute to its long-lasting performance and reliability.
• Efficient and User-Friendly Design The LG-WDR-F2 offers several features that streamline installation and operation.
• Zero dead leg control valve activation at point of use
• Simplified installation of recirculation module
• Duraline control valve with easy open/close functionality and 120-degree rotation from full flow to closed
• PTFE sealed, encapsulated PTFE shut off seal for extended life
• Black handle with white marker and black "DI" text per SEFA code recommended practice No. 7 for DI Water Applications
• Duraline control valve is completely renewable by replacing the internal cartridge DL-RC180-PVD, per SEFA 7-2010-8.2a
• Positive stop at off position
• Low torque on/off operation
• Compliance with Industry Standards The LG-WDR-F2 is designed to meet FDA, USDA, and USP standards, ensuring compliance with industry requirements for high purity applications.
• With a max flow of 2.5 GPM @ 80 PSI and no elastomers, metals, or lubricants used in construction, this faucet delivers reliable performance and purity.
• System Design Considerations The LG-WDR-F2 is designed for use with a recirculating system that incorporates a non-pressurized storage tank or reservoir.
• The non-pressurized tank provides the pressure drop for the recirculating flow to continue and return via the recirculating tube, ensuring that the water is not actually consumed.
• To reduce stagnation and bacterial growth, the LG-WDR-F2 maintains a constant flow of DI Water when the point-of-use dispense is not being utilized.
• Ideally, the flow rate of the recirculating flow stream should be 4.5 feet per second or greater to prevent bacteria and other biomass from adhering to internal surfaces.
• When piping the recirculating lab faucet in series, a common return line may be used to accept each individual recirculating tube.
• A small pressure drop downstream of each faucet may be necessary to assure a positive flow through the recirculating system and provide adequate pressure for the main water dispensing.
