Features:
1. Easy to exchange the seal ,maintenance without complex operation
2. The gap of gears is adjustable,
3. Roomy cavity allow to change packing without disassembling the pump,
4. High displacement pump can work in high pressure conditions
5. Casted temperature preservation layer in one piece, so no leakage and highly temperature insulation,
6. Several kinds packing seal together is more stronger than mechanical seal

Laifu manufactures various kind of industrial pumps, internal gear pump, external pumps, screw pumps and magnetic pumps, centrifugal pumps, with decades of manufacturing variant pumps, we have had several hundred pumps offering the markets.
