Oil and gas, chemical, metallurgical, pharmaceutical, food, water treatment

4.Background

The design determination of single seal pump requires comprehensive consideration of operating conditions (pressure, temperature, speed, medium), sealing structure types (balanced/unbalanced, number of springs, transmission mode), and material compatibility, ultimately achieved through standardized selection or customized design.
single seal pump is one of the most common forms of shaft seals in rotating equipment, widely used in centrifugal pumps, stirred tanks and other equipment
Its core function is to form a reliable seal between the rotating shaft and the housing, preventing medium leakage. When designing, it is necessary to choose the structural form, material combination, and auxiliary system reasonably according to the specific usage environment.

Design element decomposition of single seal pump
a. Confirmation of working condition parameters
The following operating conditions need to be clarified before design:
Work pressure: affects whether a balanced structure is adopted;
Temperature range: determines the material's heat resistance requirements;
Speed: affects the stability and cooling requirements of the friction pair;
Media properties: such as acidity, alkalinity, corrosiveness, lubricity, toxicity, etc.
(Additional explanation) If the medium is toxic, flammable, or does not allow leakage, double end or series sealing should be prioritized over single end sealing.

b. Structure type selection
Unbalanced, balanced, single spring, multi spring, fork drive

C. Main component composition
Main sealing components: dynamic ring and static ring (usually paired with one hard and one soft material);
Auxiliary sealing components: O-ring, V-ring or wedge ring (commonly made of rubber, polytetrafluoroethylene, flexible graphite);
Compression and transmission components: springs, push rings, transmission seats, anti rotation pins, etc., ensure that the moving ring rotates with the shaft and remains in contact.
