LZ LZV/LX PUMP
Features | Benefits |
---|---|
High-pressure/Long life | Optimal for heavy machinery such as iron making machines and press machines |
High-efficiency | Even at high pressure, there is little oil leakage inside the pump, so high efficiency is realized. |
Low noise | Reduced noise with high rigidity casing structure and independently developed internal device |
Variable control type | Abundant control methods such as constant torque type, constant pressure type, and electro-hydraulic flow control |
