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.
