Pumps for bitumen and the food industry

High-performance pumps for bitumen and the food industry

Self-priming volumetric solutions with external gears designed for the continuous and controlled handling of difficult fluids: hot bitumen, bituminous emulsions, chocolate, spreads, syrups, molasses, edible oils, and other high-viscosity products. The goal of our pumps for bitumen and the food industry is to ensure constant flow, dosing precision, and maximum reliability even in the presence of high temperatures, heavy cycles, and frequent plant shutdowns/restarts.

Each configuration is based on a detailed analysis of the fluid and operating conditions: viscosity as a function of temperature, required flow rate, head, compatible materials, and seal type are evaluated on a case-by-case basis. This approach allows us to create a truly customized pump, reducing premature wear, plant downtime, and energy consumption, and ensuring process continuity, precision, and repeatability over time.

Bitumen and food industry: our two main areas of focus

Our gear pumps for bitumen and the food industry are configured according to the specific characteristics of the process: nature of the fluid, viscosity, working temperature, feeding mode, continuity of service, and safety requirements.
This allows us to offer dedicated solutions for both the road and infrastructure sectors (bitumen and emulsions) and for food production lines with high hygiene and traceability standards.

Why a gear pump for bitumen and the food industry must be precisely sized

Unlike a traditional centrifugal pump, a volumetric gear pump for the food industry or for bitumen works with reduced clearances and tight tolerances: incorrect configuration can lead to accelerated wear, noise, vibrations, or loss of efficiency. For this reason, sizing cannot be approximate, but must take into account all the actual operating parameters of the system.

Talk to a technician specialized in pumps for bitumen and the food industry

Whether it’s bitumen, bituminous emulsions, or high-viscosity food products, talking directly with a technician allows you to quickly evaluate the most suitable solution, avoiding trial and error and subsequent modifications to the system. Together, we can analyze the existing layout, operating conditions, and production objectives, proposing a gear pump that meets your needs.

Direct phone number: 051 0910402

If you prefer, you can email or use the form to send us your system specifications: fluid, viscosity, temperature, flow rate, head, and installation layout. Based on this data, we will prepare a dedicated technical proposal and, if necessary, we will also support you during the start-up and initial calibration phases.

Process data and available configurations

The performance of a volumetric gear pump depends directly on the geometry of the gears, internal tolerances, the materials of the parts in contact with the fluid, and the ability to maintain stable temperature conditions. For applications involving bitumen, emulsions, and mastics, for example, the thermal stability of the pump body is a critical factor: a variation of a few degrees in temperature can drastically change the viscosity of the product and therefore the flow rate delivered.

For this reason, in addition to the standard versions, configurations with heating/cooling jackets, external supports for abrasive applications, mechanical seals dedicated to food products, and electronic flow rate control systems are available. The goal is to enable accurate process control while simplifying maintenance and routine cleaning operations.

Technical support from selection to commissioning

Our support is not limited to the choice of pump. We can assist you in the sizing phase, in verifying operating conditions, in defining the optimal flow curve, and in evaluating circuit pressure drops. On request, we provide installation diagrams, instructions on the correct positioning of safety valves, advice on lubrication, and hot or cold start-up cycles. A correct initial analysis avoids subsequent interventions on the system and ensures a long pump life, reducing unscheduled downtime, energy consumption, and the risk of clogging or cavitation.

Scheduled maintenance and after-sales service

Gear pumps are designed to ensure operational continuity, but like all industrial machines, they require periodic checks and maintenance appropriate to the conditions of use. In the food industry, for example, it is essential to maintain a high quality of internal surfaces to avoid contamination or residues that could alter the finished product.

In the bitumen sector, on the other hand, high temperatures and the nature of the fluid make it necessary to regularly check the cleanliness of the internal channels, the stability of the heating jacket, and the efficiency of the pressure relief valve. Targeted interventions increase the overall reliability of the system and reduce downtime costs.

FAQ – Frequently asked questions about pumps for bitumen and food products

What are the differences between a bitumen pump and a food pump?

Bitumen pumps operate at high temperatures and require heating jackets and materials resistant to the extreme viscosity of the fluid, while food pumps are made of stainless steel with high-finish internal surfaces, suitable for C.I.P. processes and high hygiene standards.

Can the pumps handle highly viscous fluids?

Yes. Positive displacement gear pumps are ideal for high-viscosity fluids such as mastics, creams, chocolate, molasses, or bitumen. Reduced internal tolerances ensure constant flow even in the presence of variable viscosity.

Is external heating required for bitumen?

Yes, almost always. Versions with a heating jacket maintain the fluidity of the bitumen, preventing internal hardening that could block the rotor or reduce the flow rate.

Can the pump flow rate be adjusted?

The flow rate can be adjusted using inverters, dedicated valves, or electronic control systems. For food and dosing processes, we recommend configurations with fine speed adjustment.

What data is needed to correctly size the pump?

For an accurate configuration, we need: viscosity, working temperature, required flow rate, head, type of fluid, and circuit layout. With these parameters, we can propose a precise technical solution.
