Balance Seals

Single Spring Balanced Mechanical Seal

Balanced face design that reduces hydraulic closing force on the seal faces, lowering heat generation and wear
Single large-coil spring construction that resists clogging in slurry, fibrous, and solids-laden fluids
Non-clogging, self-cleaning spring geometry suited for dirty or contaminated media
Compact single-spring assembly for straightforward installation and maintenance
Broad chemical compatibility through interchangeable face and elastomer combinations
Stable sealing performance under fluctuating pump pressure and speed conditions
Cost-effective alternative to multi-spring seals for general-purpose and moderate-duty pump service

PRODUCT DESCRIPTION

Engineered for Reliable Performance in Demanding Pump Applications

Installing a single spring balanced mechanical seal involves mounting the rotating assembly onto the shaft, compressing the spring to the correct working length, and securing the stationary seat squarely within the seal chamber before final alignment checks. Getting the spring compression and face squareness right is critical, since even minor misalignment can lead to premature face wear or leakage. Beyond ease of fitment, this seal design offers real operational advantages — lower maintenance frequency in solids-laden fluids, extended face life from reduced hydraulic loading, and dependable sealing across varying pump speeds and pressures.
