Liquid Oxygen Pump

Product Details

 

Liquid oxygen pumps are centrifugal or reciprocating fluid handling units specifically designed for the pressurized transfer of liquid oxygen. They are widely used in air separation units, aerospace launch site fueling systems, iron and steel smelting, and chemical production. Manufactured by Hangzhou Tubo Energy Technology Co., Ltd., these pumps are engineered to handle the strong oxidizing nature, cryogenic temperatures, and high-purity requirements of liquid oxygen. Wetted parts are constructed from specialized stainless steel or copper alloys compatible with liquid oxygen, and the manufacturing process employs rigorous degreasing and clean-assembly protocols to prevent contamination and material incompatibility risks. The pump units feature either horizontal or vertical configurations, allowing for flexible customization based on flow rate, head, and installation space requirements.

The centrifugal models offer flow rates ranging from 0.5 to 1,250 m³/h and heads up to 2,600 meters, while the reciprocating models cover flow rates from 0.4 to over 200 m³/h and pressures between 25 and 100 MPa. These pumps meet the transfer needs of various applications, including liquid oxygen tanker filling, storage tank pressurization, high-pressure gasification supply, and rocket fueling. Before shipment, every unit undergoes comprehensive performance testing using liquid nitrogen as a substitute medium on the company's in-house cryogenic test rig; third-party inspections or on-site witness testing by the customer can also be arranged, with full test reports and certificates of conformity provided.

The company's core team possesses extensive experience in the R&D of cryogenic fluid equipment for the air separation and aerospace sectors, having led multiple national-level research projects related to liquid oxygen pumps. Recognizing that these pumps are critical safety equipment, the company enforces a strict three-tier quality control process-covering incoming material inspection, in-process control, and final inspection-to ensure every unit meets design specifications and customer requirements. The typical lead time for customized products, from technical approval to delivery, is 32 weeks, with the exact schedule determined by technical complexity. After-sales services include on-site installation and commissioning guidance and spare parts supply as stipulated in the contract, as well as support for obtaining classification society certification.
