Cantilever monoblock pumps of the SAER IR series are centrifugal, single-stage pumps manufactured in Italy. It is usually used for fluid circulation and pressure increase in heating, air conditioning and water supply systems, for irrigation. The mechanical seals used in SAER IR-bellows pumps are single, manufactured in various materials depending on the medium being pumped (in the standard version Q1 V E GG). In this case, the seal failed due to mechanical wear and we replaced it with a mechanical seal R-MG1S20 28, CAR/SIC, EPDM, 304, G60. Such an alternative is quite reasonable both in terms of cost and in terms of reliable and long-lasting operation.

Mechanical seal movable FG/28 SIL-EPD 97954 MT and mechanical seal stationary to FG/28 ALO-EPD 92123 MT is used for pumps SAER IR/IR4P 32-200 NA/NB/NC, 32-250, 40-200, 40-200N, 40-250, 40-250N, 50-160, 50-160N, 50-200, 50-200N, 50-250N, 65-160, 65-200, 65-200N, 80-160. Article 54250830 / 54200530.

There are several points that you should pay attention to when choosing and installing a seal :

  • When pumping media with abrasive components, increased wear of the hydraulics and the shaft seal should be expected. In this case, it is necessary to reduce the usual intervals between inspections.
  • When installing the seal, to reduce the friction forces, moisten the shaft sleeve and the seat of the fixed ring of the mechanical seal with water.
  • The mechanical seal has a slight or imperceptible leakage (in the form of steam) during operation.
  • Increased wear due to dry running! If possible, never allow it .

KSB pumps of the Etaline PumpDrive series are designed for pumping liquids that are not chemically aggressive in heating, water supply, etc. By design, Etaline is a monoblock pump with a horizontal nozzle arrangement in one line -"inline".
