SAMCO Equiseal Dynamic Seal pumps are designed to
reduce stuffing box sealing problems normally found with
packing or conventional mechanical seals. Equiseal
DynamicSeals are used for severe corrosive and abrasive sealing
applications in the chemical, petro-chemical, pulp and paper,
brewing, food and other process industries.
No sealing or flushing liquid required for majority of
applications. For extremely severe applications, a special
flushing protection with differential over suction pressure
15 kpa and a small amount of clear liquid (less than 0,4 l/min)
guarantees long expeller and static seal life.
Simple operation The Equiseal Dynamic Sealuses an
auxiliary impeller in the stuffing box. As pumped liquid enters
the Equiseal Dynamic Sealstuffing box cavity, it is opposed
by centrifugal forces, generated by the auxiliary impeller, thuspreventing leakage when applied correctly.
Static sealing When the pump is not in operation, a
replaceable sealing ring or disc acts to retard external leakage
along the shaft.
No critical operating clearances are required for proper
operation of the Equiseal Dynamic Seal.
Packing is eliminated thus greatly reducing stuffing box
maintenance.
Mechanical shaft seals with finely lapped faces and
expensive replacement components are no longer required.
All pumps with packing or mechanical seals can be
converted readily to Equiseal Dynamic Sealin the field.
Capability Manufactured in 1, 2, or 3 stage designs
which balance out positive suction heads over a wide range.
Available in various pump sizes with the same Equiseal
Dynamic Sealparts in each frame group.
CSO Utilizes ANSI B73.1 standards. Retains the
advantages of the STANDARDS PUMP with back pull-out,
fully open impeller, top centre-line discharge and long bearing
life.
Rear pull-out design Retains the advantages of the
standard pump with back pull-out. Fewer crafts are required to
service pump.
Metallurgy Pump wet-ends are available in any
machinable metal, normally suited to specific applications.
