CrNiMo steel

Ra ≤ 3,2 µm

Design
Inter-stage,discharge and suction casings manufactured from heavy duty, deep drawn, rolled stainless steel 1.4404 corresponding to AISI 316 L, and 1.4571 corresponding to 316 Ti. Impeller, semi-open or closed in rolled stainless steel quality 1.4404 or. 1.4571 (gentle pumping action).

Shaft seals:

Single internal, mechanical ring seals positioned in the product flow ensures ample cooling and easy cleaning. The materials are selected to be compatible with the media.

Option:

Double mechanical seal in tandem design or back-to-back arrangement with flush and barrier water connections.

Connection types:

  • Threaded fittings to DIN 11851
  • Flanges to DIN 2642 PN 10
  • Flanges to DIN 2656 PN 40

Other connections available conforming to the following standards: SMS, RJT, IDF, clamp connections to DIN ,ISO and other standards, special sterile threaded fittings and special small sterile flanges.
