RC
RC pumps are single-stage pumps equipped with vortex impeller recessed within the casing. This configuration allows most of the liquid to pass through the pump without coming into direct contact with the impeller.
This feature offers significant advantages in transporting various elements such as crystals, delicate solids, agricultural products, biological sludge flakes, and leather residues without causing damage, as well as in conveying long and filamentous solids without the risk of clogging

Technical features
➊ Free passage of big solids
Free passage up to 90% of the discharge port diameter: Thanks to its recessed arrangement, the impeller allows the passage of spherical solid bodies up to 90% of the discharge port diameter (see technical tables for further details).
Long and filamentary solid pass through the pump without any risk of clogging.
➋ 1 casing cover, 12 seal arrangements
For every size of pump, a unique casing can hold any kind, brand and choice of seal.
The seal chamber dimensions are designed to guarantee an efficacious and correct liquid circulation. By changing a few components, the seal arrangement can be easily modified, thus making the pump ready for new plant or process requirements and reducing the spares stock.
Mechanical Seals comply with EN 12756 standard.
➌ Heavy duty bearing housing EN ISO 5199
The bearing housing is standardized according to EN ISO 5199 and guarantees a shaft deflection < 0,05 mm and a minimum of 18.000 working hours.
It is designed to optimize axial and radial thrusts as to drastically reduce operating temperatures.
All bearing housings are suitable to host the heavy duty version “HD” which is equipped with angular contact bearings and roller bearings. These series also include a stronger bearing housing able to operate up to 100.000 working hours.
➍ Casing design
The inner smooth surface of the pump casing avoids material build-up and dimensions of components prone to wear have been accurately studied to guarantee a long-lasting and reliable performance.
RC pumps are mainly used in the following sectors
