Casing Design

z Problem wear areas have always included the casing cutwater and wearplate surface.

z Computer solidification modeling allows extra thickness at crucial wear points for extended life.

Extra Thickness

Solidification Modeling

z Corrosion has less effect on large section components such as our impeller lock nut.

z Crevice corrosion is reduced through the use of o-rings at the critical fluid joints.

O-ring moves over the corroded & fouled casing surface

Sideplate floats on studs- cocking in casing- studs can shear- not precise adjustment

Leakage past o-ring has leakage path through studs

Evolution of Sideplate Adjustment

Converting closed impellers to open was economically accomplished using adjustable sideplates.

The majority of pump downtime is due to mechanical

seal or packing failure.

Pump manufacturers frequently imply L3/D4ratios yield longer seal life.

Shaft deflection is a function of low L3/D4 and lower radial loads.

All reputable pump manufacturers have deflections under 0.002 in.

Low radial load = low deflections

Shaft Deflection

Leading seal manufacturersreport that shaft deflection is NOT

the cause of seal failures!The problem is SEAL ENVIRONMENT!

Mechanical Seals

Seal Environment is Criticalfor Extended Seal Life

Seal Chambers Initially

Designed for Packing

Big Bore Seal Chamber Taper Bore Seal Chamber

(Introduced in the mid 1980s)

Evolution to Large Bore Seal Chambers to Extend Seal Life

Conventional taper bore seal chamber mechanical seals fail when vapor or solids are present

Modified tapered bore seal chamber with axial ribs good for services containing air, minimum solids

Goulds standard tapered bore plus seal chamber the best solution for services containing solids and air or vapors

Taper Bore Evolution

1) Solids/liquid mixture flowstoward seal chamber

2) Turbulent zone

3) Clean liquid flows towards seal

4) Low pressure zone createdby vane particle ejector

5) Seal faces flush with clean liquid

Taper Bore Plus How it Works
