Working conditions
Mechanical seal type V2M is designed for light working conditions, for the pressure up to 10 bar ° 4°
–40°C~204°C Our Mechanical Seals proved themselves especially at following medium °
diary and natural juice
-
-
and ammonia H
(p = 10 bar) and temperatures from minus 40 C to 20 C(t = ).
: cold and hot water up to 130 C, demineralized water, wastewater,beer, beer mash, malt, milk and product, juice , mild acid,mild alkal (base) (N 3) .
Design and constructive characteristics
long compre of the single coil spring compensates play and the differences in the working length It can be built intoboth DIN 24960 standard (EN 12756) measurement outof DIN 24960. otary part is extremely flexible, suitable
, and the sole mechanical seal is mounted easily.
Extremely short rubber bellows with ssion ratio -.
and shorter, also longer sThe r and for most applica-
tions
