Used CTI-CRYOGENICS OB-4F (On-Board) #293634484 for sale

CTI-CRYOGENICS OB-4F is a robust, self-priming cryogenic rotary pump which is designed for the transfer of liquefied gases. This pump is capable of providing a continuous flow of up to 30gpm (114 lpm) and accurately delivers pressures up to 1,000 psig (68.94 bar). With a single-stage operation, the OB-4F is ideal for usage in cryogenic applications, due to its powerful motor and long-lasting construction. The OB-4F features a durable, mechanically-sealed construction, and incorporates a unique single impeller design. This variation of the impeller utilizes a one-piece hub that eliminates shaft wobble, reducing internal frictional losses. This also reduces the maintenance and wear of mechanical components, providing improved bearing life and overall performance. The OB-4F is designed with a lubricant-free gearbox, eliminating environmental contamination and ensuring a continuous and reliable flow of cryogenic liquid. As an additional safety measure, the motor undergoes an advanced thermal protection system to further protect against corrosion, electrical wear, and motor failure. The pump's single-stage design allows for an optimal range of capabilities, allowing the user to increase the pressure slightly while maintaining flow rate while still allowing for delicate liquids to be handled. With its compact body and utilizing quick-connects, this pump has the ability to be installed in a system quickly and easily. For cryogenic applications, the OB-4F is constructed with highly-resistant stainless steel for rust, wear, and corrosion prevention. Its specially designed components ensure protection from the cold temperatures of cryogas and the extreme conditions oftentimes seen in cryogenic applications. The OB-4F is ideal for the transfer of cryogenic liquids such as nitrogen, oxygen, argon, and many specialty gases. It performs efficiently, operating on extremely low power with no moving parts in contact with the liquid. Its dependable, safe operation makes the OB-4F an ideal choice for industrial applications, as well as commercial and scientific research.
