RS
RS pump 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 Solid free passage
Free passage up to 70% of the discharge port diameter: thanks to its recessed arrangement, the impeller allows the passage of spherical solid bodies up to 70% of the discharge port diameter (see technical tables for further details).
Long and filamentary solids pass through the pump without any risk of clogging.
➋ 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.
➌ Standard electric motor
RS pumps motors are unified according to IEC standard type B3B5 (flange/feet execution) and they are easily available on the market.
The pump shaft is fixed on the motor one and it can be easily replaced in case of wear.
RS pumps are mainly used in the following sectors
