Specializing in liquefied gas transfer, our product line incorporates small, medium, and large capacity positive displacement pump models for intermittent or continuous duty service for domestic and global markets. Such applications include cylinder filling, bulk transfer for truck/ISO containers, Autogas, and recirculation/thermal testing to name a few. Industries include LP-gas (propane), anhydrous ammonia (NH3), carbon dioxide (CO2), refrigerants, and other specialized heat transfer fluids ranging from 2.5 to 250 GPM (10 to 945 LPM) flow capacity. We also manufacture accessory items such as differential type bypass relief valves, flexible drive couplings, and Y-type strainers. Other products include Smith chemical injectors, well-known for accuracy, dependability and superior quality. We offer a complete line of water-powered injectors and accessory items for flow rates of 3- 100 gallons per minute for commercial nursery and other agricultural applications. Smith injectors are designed with options specifically suited for many types of chemicals.
