Please Note:
Maximum differential pressure capability of the pump does not apply to the pressure rating of the mechanical seals which is
20 bar, and the selected port connection as stated below:
SMS – 10 bar (all sizes)
RJT – 10 bar (all sizes)
DIN11851 – 40 bar (25-40mm), 25 bar (50-100mm), 16 bar (150mm)
IDF/ISS – 16 bar (25-50mm), 10 bar (65-150mm) providing provision for support ring is to be made.
Tri-clamp (BS4825) – Pressure rating is dictated by the clamp band used.
Refer to clamp band supplier.
For size 150mm on SRU6/0353 pumps, only DIN11851, SRJT or Tri-clamp connections are available.
Note:
ATEX applications: Differential pressure, Max. speed and Max. capacity are not applicable for ATEX applications.
