The Model 600
Dual Stationary Cartridge Mounted Seal
Performance in Motion
The
ASI Model 600 is specially engineered to withstand greater radial and axial
movement common to larger equipment such as slurry pumps, mixers and agitators.
The seal components are designed to work in unison, preventing under- or
over-compression of the seal faces, as well as increasing free movement of the
seal.
Unison Component Design- One set of springs, independent of the seal gland plate, energizes both stationary faces. Anti-rotation devices are positioned to give seal components maximum movement. This allows the seal to move freely with the pump shaft without increasing or decreasing the mechanical seal load on the inboard or outboard seal faces.
Greater Radial Clearances- The Model 600's design incorporates greater radial clearances between individual seal components, enabling the seal to compensate for increased shaft whip or radial thrust.
The Model 510
Dual Rotary Cartridge Mounted Seal
Strength in Design
Developed
to address the inherent problems associated with hot polymer, pre-polymer,
monomer and plastics applications, the Model 510 is the only canister-type
double seal engineered with reciprocally balanced seal faces.
Low Expansion Metallurgy- The Model 510's seal components are designed with the maximum possible cross-sections and constructed with low expansion metallurgy preventing the seal face distortion normally caused by pressure spikes and high temperatures.
Reciprocal Balance- The reciprocal balance of the Model 510 compensates for the varying pressures between normal service (vacuum) and spikes that often occur. This ensures the optimum seal face closure and prevents barrier fluid contamination, providing uninterrupted seal service during the spike, and after normal service resumes.
