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
