Marzocchi gear pumps

The 1P gear pumps from Marzocchi offer a complete range of powerful aluminium pumps that cover all the requirements of a genset application and are also suitable for various mobile and industrial applications. Assembly 1 has a flow rate from 1.1 to 8 cm³/rev. The max. operating pressure can reach up to 230 bar, depending on the design. The 1P series is characterised above all by its resistance to vibrations and thermal shocks.

The following versions are available:

Available funding volumes can be seen in the following diagram:

The ALP series gear pumps are divided into 4 groups. Each group has different delivery volumes (1.4 to 200 cm3/rev), which are achieved by varying the gear wheels. Different flanges, shafts, suction and discharge connections are available.

In particular, the following versions are available:

SPECIAL VERSIONS

Versions for special applications are also available:

V: Version for use with high temperature medium. Application range from -10°C to +120°C. Between -10°C and +80°C pressure P1, P2 and P3 are permissible, above this P1 should not be exceeded.

W: Version for use with high temperature medium. Application range from -10°C to +150°C with maximum pressure 20 bar.

ST: Version for use with high and low temperature medium. Application range from -40°C to +120°C. Between -10°C to +80°C pressure P1, P2 and P3 is permissible, above this P1 should not be exceeded.

H: Version for use with low temperature medium. Application range from -40°C to +80°C. Between -10°C and +80°C pressure P1, P2 and P3 are permissible, above this P1 should not be exceeded.

TR: Version for use with suction pressure up to 6 bar.

The GHP series has the same features and sizes as the ALP family of pumps but with extreme reliability for applications with particularly high pressure ranges. In addition, the flexibility of the cast iron allows for a wide range of flanges, covers and connections, making this series ideal for use in mobile applications, agricultural and construction machinery in general.

The Marzocchi micropumps are produced in 2 sizes: 0.25 and 0.5. By varying the gears, the corresponding delivery volume can be achieved. Different flanges, shafts, suction and discharge connections are available.

In particular, the following versions are available:

Additional special versions are available with the option /V, /ST and /TR. For further explanations see above.

ELIKA is the solution for all applications that require a low noise level and high efficiency, especially at low speed. ELIKA effectively reduces the noise level by 15 dBA compared to traditional external gear pumps. The maximum working pressure is similar to the GHP series (cast iron/aluminium), reaching 300bar. In particular, the gearing profile results in a reduction of pressure vibrations and the transmission of less vibrations to the components connected to the pump (hoses, tank, valves), an advantage for the entire hydraulic system. The elicoid gearing guarantees constant movement despite the low number of teeth. Again, the low number of teeth significantly reduces frequencies, resulting in a particularly pleasant noise emission.

ELIKA pumps are ideally suited for all hydraulic solutions for industrial applications, such as presses, machine tools and testing machines, paper machines, waste compactors and pumps for lubrication systems. Due to increasingly strict regulations in the mobile sector, the ELIKA pump is also ideal for applications such as material handling systems, lifting platforms, street cleaning and refuse collection vehicles. ELIKA also offers an excellent solution for applications ranging from offshore and shipbuilding to new energy sources, where noise emission is crucial.

Due to the permissible speed range, ELIKA is ideal for applications with variable speed drives. In such systems it is effectively possible to replace a variable displacement pump with the ELIKA fixed displacement pump and frequency converter with significant cost savings. The use of an ELIKA pump with a variable speed drive means a significant reduction in the noise emission of the entire system, reduction of pulsations, increased comfort for the user in mostly critical and demanding applications.

The ALM1, ALM2 and ALM3 series geared motors are suitable for a wide range of applications in both industrial and mobile applications and meet the highest quality standards. They are characterised by a low noise level, deliver a high torque and also work under difficult operating conditions.

The available displacements for the ALM1 group are between 1.4 and 13.8 cm³/rev, for the ALM2 group between 4.5 and 35.2 cm³/rev and for the ALM3 group between 20 and 87 cm³/rev.
