Marzocchi gear pump ALP series product description
Marzocchi Gear Pump ALP Series Product Models
The Marzocchi ALP series gear pumps feature a full aluminum configuration, capable of withstanding medium to high pressures, and are available in four main groups (ALP 1, ALP 2, ALP 3, ALP 4) with multiple sub-models. They cover different displacements, speeds and application scenarios, suitable for both industrial and mobile sectors. The specific models are listed as follows, along with key technical parameters for reference:
1. ALP 1 Series
Displacement range: 1.4 – 13.8 cc/rev; Max speed: 2000 – 6000 rpm; Max continuous pressure: 250 bar; Max intermittent pressure: 270 bar; Max peak pressure: 290 bar; Suitable for compact hydraulic systems requiring high speed operation.

Note: The “D(S)” in the model represents the installation and rotation direction, and the specific parameters (such as flow rate, pressure grade, flange type) vary with the model. The ALP series is equipped with different flanges (European, German and SAE) and porting options. For detailed order codes and dimensional parameters, please refer to the official Marzocchi product catalog.
