A double cartridge seal with a “back to back” arrangement which permits operation with barrier fluids in excessive pressure conditions with respect to the working fluid (P1 + 1.5 – 2 kg/cm²). For this reason it is advisable to install it in applications with toxic, contaminant or potentially dangerous fluids in where safety is an important factor.

Connections:

• 3/8” NPT.
• For 25, 28 and 30 mm shafts the connections are at opposite sides of the flange.

OPERATING LIMITS:

V= 20m/s

p= 20kg/cm²

d = 25 ÷120mm

t= -15 ÷ +200⁰C
