1 Product description Receiver Fro Ite Quant. Description SERIES SKD AXIAL SPLIT CASING PUMP /in USES Recircling plants, heating, air conditioning, heat recov ery, plants of water supply procureent, pressurising units and f iref ighting sy stes. CONSTRUCTIVE CHARACTERISTICS SKD: axially split v olute casing centrif ugal pups, to be coupled with electric or engine otor The otor unit and the rotating part of the pup can be taken away without reov ing the pup body f ro the sy ste piping. Double entry radial ipeller dy naically balanced. Double design v olue to iniize the radial thrust on the bearing. Pups prov ided of double wear ring (on ipeller side and boby pup side). Pups coated with cataphoresis epoxy based coating. SHAFT Material :Stainless steel AISI 3 (.57) The shaf t is protected by the stuf f ing box with stainless steel or bronze sleev e.

5 Advantages Advantages /2 Wear ring: double wear ring, pup f itted with casing wear ring and ipeller wear ring 3 Shaf t: The shaf t is ade of stainless steel, adequately sized f or the loads transitted. The shaf t is protected through the stuf f ing box with stainless steel or bronze sleev e. The sleev es are f itted with O rings with inside diaeters to eliinate leakage between the shaf t and the sleev e. / Casing: Double design v olute: the radial thrust on the bearing is iniu and lower than the one with single v olute design. High ef f iciency design. 5 Sof t packing (standard) or echanical (on request) Ipeller: One piece casted ipeller, with double suction. Due to the ipeller double suction design there s no axial thrust on the bearings. Ev ery ipeller is balanced statically and dy naically. Ipeller key ed to the shaf t and axially f ixed by two half rings: due to this solution, aintenance and ipeller disantling are sipler than the one with threaded shaf t sleev es. 7 Bearings: Two heav y duty ty pe bearings grease lubricated with grease f lush through the bearing housing. The bearing bracket is caref ully sealed of f on both sides to prev ent water or containants f ro seeping in. The bearing are protected f ro liquid entry by eans of rubber seals Long lif e bearing designed f or an av erage lif e of. hours, continuous running (MTBF). ID
