The Cryogenic Centrifugal Pump is a high-precision fluid handling solution tailor-made for extreme cryogenic working conditions, especially for liquid oxygen transfer scenarios. Integrating optimized high-speed hydraulic design, heavy-duty explosion-proof construction and reliable sealing system, this pump delivers stable, efficient and safe performance when transporting cryogenic media at temperatures as low as -196°C. Ideal for compact industrial installations requiring high-head cryogenic fluid transfer, the SLP-40/90 redefines operational reliability and space efficiency for small-flow, high-lift cryogenic applications.
Core Performance Advantages
High-Head Compact Design: Optimized 3600r.p.m high-speed hydraulic structure delivers a rated head of 90m with a small flow of 40m³/h, featuring an ultra-compact horizontal footprint, perfect for space-limited industrial installations and skid-mounted integrated systems.
Ultra-Low Temperature Stability: Engineered with cryogenic-resistant stainless steel materials and precision-machined components, the pump maintains consistent and stable performance even at a design temperature of -196°C, eliminating risks of material brittleness, cold shrinkage deformation and medium leakage during long-term operation.
Global Market Adaptability: Equipped with a 440V 60Hz explosion-proof motor that complies with international explosion-proof standard EXdII BT4 Gb, IP55 protection level and Class F insulation, fully adapting to the power grid standards and safety requirements of the Americas, Southeast Asia, Middle East and other overseas markets.
High Efficiency & Energy Saving: The precision-molded 3D impeller and optimized flow channel design minimize hydraulic loss and turbulence, effectively improving pump efficiency, reducing energy consumption and long-term operating costs for customers.
Safe & Reliable Sealing System: Adopts an imported high-performance cryogenic sealing system with a continuous service life of no less than 3 months, specially designed for liquid oxygen media, ensuring zero leakage and absolute safety during the transportation of flammable and explosive cryogenic media.
Easy Maintenance & Operation: Modular integrated design simplifies disassembly, inspection and parts replacement, with standardized universal spare parts to minimize equipment downtime. The matched control cabinet realizes one-key start/stop and full overload protection, making on-site operation simple and safe.
Quality Assurance
Complies with international industry standards: ISO 9001 quality management system, API 610 standard for centrifugal pumps, and relevant cryogenic equipment safety specifications.
Each pump undergoes strict factory testing before delivery, including cryogenic performance test, hydraulic performance test, pressure resistance test, seal leak detection and no-load running test, ensuring 100% qualification rate of outgoing products.
We provide a 12-month global warranty, and 24/7 professional technical support, including installation guidance, maintenance training and troubleshooting services for customers worldwide.
