LM481 Special Gear Pump
There is a spiral anti-fouling groove on the surface of the rotor part to prevent the pump from being stuck due to crystals. LM481 gear pump has strong corrosion resistance, wear resistance, high viscosity resistance.The design speed of the impeller pump takes good care of the viscous characteristics of water glass.

2. Good lubrication and long service life:
good lubrication conditions extend the service life of the pump.
3. Simple structure, high working stability:
simplifies the maintenance and repair process and improves the reliability of work.

Materials: carbon steel
Stealing : Packing seal
Installation: motor installation, foot installation

Working Conditions & Application Advantages
Wide viscosity adaptability: handles viscosities ranging from 1 to 500,000 cps, delivering stable transfer for room-temperature liquid MDI and low-temperature thickened isocyanate. Excellent self-priming performance; the pump feeds smoothly under slight pipeline negative pressure, ideal for feeding from low-position storage drums. Compact structure with easy disassembly and assembly, facilitating material changeover and cleaning. Residual medium can be fully drained during shutdown to prevent solidification and gear seizure inside the pump. Explosion-proof configuration available: matched with explosion-proof motors to comply with safety standards for chemical workshops, as isocyanate is volatile and flammable.
