Monobloc pumps ensure a linear, pulsation-free, and measurable flow rate for a wide range of fluids, from low-viscosity to very high-viscosity products, whether fibrous or granular, and even those sensitive to foaming and crushing. Thanks to the absence of turbulence and the minimal shear they generate, they preserve the product structure and fibers. This represents a significant advantage for transfer and dosing operations requiring a constant flow rate while maintaining quality, particularly in the production of jams, molasses, syrups, creams, slurries, and polyelectrolytes.

Depending on the configuration, flow rates of up to 300 m³/h and outlet pressures of up to 72 bar are possible. The wide operating temperature range extends from -30 °C to +300 °C. With its high self-priming capability, it enables vacuum suction to a depth of approximately 8.5 meters. Performance is maintained by adjusting the speed/fill ratio according to viscosity increases. Thanks to its appropriate rotor-stator geometry and speed, a stable flow rate is achieved even with semi-solid fluids and those containing particles.

For the body and parts in contact with the fluid, cast iron, AISI 316 stainless steel, and special alloys are available, while for elastomers, NBR or Viton can be used. The choice should be based on the chemical composition of the fluid, the temperature, and hygiene requirements. Viton is preferred for its chemical resistance and high-temperature performance, while NBR is practical and economical for food-grade and non-corrosive fluids. For hygienic applications, smooth-surface stainless steel configurations, CIP/SIP compatibility, and preferably hygienic series conforming to EHEDG/3-A are preferred.

In a monobloc pump, the flow rate varies almost linearly with speed, allowing for very precise control using a frequency inverter. The integration of analog/digital signals into PLC/SCADA systems enables scenarios such as constant flow, gradual ramp-up, weighing, or dosing via feedback. The low, pulsating flow rate improves filling repeatability and simplifies process control.

The main consumables are the stator and rotor surfaces, as well as the sealing elements. Abrasive particles, high temperatures, and an inappropriate choice of elastomer reduce their service life; maintenance intervals can be extended with suitable materials, correct rotational speed, and adequate suction conditions (NPSH). Basic good practices include avoiding prolonged dry running, reducing friction in the piping for viscous products, and performing periodic visual inspections. The modular design of monobloc pumps allows for quick disassembly and replacement of parts, thus minimizing downtime.
