Product details

Vivolo Marzocchi is a well - known Italian brand in the field of hydraulic components, particularly renowned for its high - quality gear pumps. These pumps are widely used in various industrial applications due to their reliability, efficiency, and durability.

Product Types and Features

1. External Gear Pumps

• Design Principle: External gear pumps operate on the principle of two meshing gears (a driving gear and a driven gear) that rotate within a pump housing. As the gears rotate, fluid is trapped between the gear teeth and the housing walls and is carried from the inlet to the outlet.

• Advantages:

• High Efficiency: They offer relatively high volumetric efficiency, which means they can deliver a consistent volume of fluid per revolution.

• Compact Size: The design allows for a compact and lightweight construction, making them suitable for applications where space is limited.

• Simple Construction: With fewer moving parts compared to some other pump types, they are easier to maintain and repair.

• Applications: Commonly used in mobile hydraulic systems such as in agricultural machinery (tractors, harvesters), construction equipment (excavators, loaders), and material handling vehicles (forklifts).

2. Internal Gear Pumps

• Design Principle: Internal gear pumps consist of an inner gear (rotor) and an outer gear (ring gear). The rotor has fewer teeth than the ring gear, and as they rotate, fluid is drawn in and discharged through the appropriate ports.

• Advantages:

• Low Noise Operation: They generally operate more quietly than external gear pumps, which is beneficial in applications where noise reduction is important.

• Good Self - Priming Capability: Can draw fluid from a lower level or a partially filled reservoir, making them useful in applications where the pump may not be fully submerged in the fluid.

• Applications: Often used in industrial processes such as in chemical processing, lubrication systems, and in some food and beverage processing applications where quiet operation and self - priming are required.

Technical Specifications

1. Flow Rates: Vivolo Marzocchi gear pumps are available in a wide range of flow rates, from relatively low - flow models suitable for precision applications to high - flow pumps for heavy - duty industrial use. The flow rate can vary from a few liters per minute to several hundred liters per minute, depending on the pump model and operating speed.

2. Pressures: They can handle a variety of pressure requirements. Some models are designed for low - pressure applications (up to a few hundred bar), while others are capable of operating at high pressures (up to several thousand bar) for demanding hydraulic systems.

3. Viscosity Range: The pumps can handle fluids with different viscosities. They are suitable for pumping a range of hydraulic oils, from low - viscosity synthetic oils to high - viscosity mineral oils. Some models can also handle non - hydraulic fluids such as certain chemicals and food - grade liquids, depending on the materials used in the pump construction.

4. Materials: The pump components are typically made from high - quality materials such as cast iron, steel, and sometimes special alloys. This ensures durability and resistance to wear, corrosion, and chemical attack, depending on the application requirements.
