Metal And Plastic Magnetic Pump For Refrigerant

Magnetic-drive refrigerant pumps designed for leak-free, low-maintenance operation in refrigeration systems. Available in metal or engineered-plastic pump heads, these pumps use a magnetically coupled drive so the motor turns an outer magnetic rotor while an inner magnet and integrated impeller rotate synchronously inside a non‑metallic isolation sleeve. The conveyed fluid is fully contained within the sleeve, eliminating dynamic shaft seals and the associated leakage and maintenance problems.

Key features

• Magnetic coupling: outer (active) and inner (passive) magnets transmit torque without a physical shaft penetration, preventing refrigerant or oil leaks.
• Integrated impeller/inner magnet: compact construction and reliable rotative drive.
• Isolation sleeve: made from corrosion‑resistant, high‑strength engineering plastics or stainless steel to separate the pumped fluid from the motor and bearings.
• Construction options: metal or plastic pump bodies to match compatibility and cost requirements.
• Leak‑free sealing structure: removes the need for mechanical seals and reduces downtime and maintenance.

Benefits for refrigeration applications

• Refrigerant circulation: safe handling of liquid refrigerants without seal leakage, improving system safety and compliance.
• Refrigerated oil circulation: suitable for oil return and oil separation duties, helping maintain compressor lubrication and system efficiency.
• Cooling water circuits: can replace traditional mechanically sealed circulation pumps where refrigerant corrosion or leakage is a concern.
• Reduced footprint and maintenance: compact design and elimination of seal replacements lower pump room space and lifecycle service needs.
• Precise control: suitable for installations requiring accurate flow and pressure control in refrigeration subsystems.

Typical use cases

• Liquid refrigerant transfer and metering
• Refrigeration oil circulation and recovery
• Cooling water circulation in commercial and industrial refrigeration plants

Materials and compatibility

• Isolation sleeves: corrosion‑resistant engineering plastics or stainless steel
• Pump heads: selectable metal or plastic to match chemical compatibility with refrigerants and oils

Notes

• These pumps are intended for refrigeration-industry fluids; confirm material compatibility with specific refrigerants and oils for your application before selection. Technical performance details (flow, head, temperature and pressure ratings) vary by model and should be verified against your system requirements.
