Marzocchi HL High-low Gear Pumps

The HL gear pumps are an excellent solution when you need quick actuator speeds at low loads and slow actuator speeds at high loads. Designed for use in trash compactors, log splitters, clamping, metal forming, etc., the HL pumps require a less powerful motor compared to traditional pumps.  Flexible configuration of the pump means that all displacement combinations for the two stages, flanges and shafts are available.
