Transcription

1 Variable Speed Multi-Stage Vertical Pups (ax 9 rp) Construction Vertical ulti-stage pups with suction and delivery connections of the sae diaeter and arranged along the sae axis (in-line). Corrosion-resistant bearing sleeves lubricated by the puped liquid. MXV-E (AISI ) Internal parts in contact with the liquid in chroe-nickel stainless steel, with pup casing and upper cover in cast iron for MXV-E --. MXVL-E (AISI L) Internal parts in contact with the liquid in Cr-Ni-Mo AISI L, including pup casing and upper cover for MXVL-E --. Applications Building services pressure boosting. Water supply to ulti-storey buildings. Washing plants. Industrial pressure boosting systes. Perforance curve adjustent for industrial syste application. Operating conditions For clean non-explosive liquids, without solid, filaentary or abrasive atter (with adaptation of sealing aterials on request). Teperature of liquid: fro - C to + C.
