The front part (volute casing or pump body) is the main part of the hydraulic section into which water enters from the suction stub and is discharged through the discharge stub.
This part is intended for ESPA Niper 1 and NOX 25 pool pumps and, together with the impeller and the rear body, forms the complete pump hydraulics.
Replacement is needed in the event of cracking of the body, erosive damage to the inner surface or leakage at the joint with the other pump parts.
The original version guarantees the precise fit of all components and thus the maximum hydraulic efficiency of the restored pump.
