A double mechanical seal is a type of mechanical seal with two primary seals or sets of faces, it can operate in various arrangements with a) a barrier (containment) between the sets of faces or b) a buffer (mixing).There are three ways seal faces are configured / arranged in double mechanical seals: Back-to-Back, Tandem, and Face-to-Face. Each configuration has its own strengths which are addressed below.Double (or dual) mechanical seals are designed to ensure maximum sealing safety. These seals virtually eliminate leakage of the fluid or gas being handled in pumps or mixers. Double seals provide a level of safety/zero emissions compliance not possible with single seals.

Single Spring Mechanical Pump Shaft Seals are the most common type of pump seal. A single pump spring seal will have a single spring coiled in a right or left-hand design. This design in position will help accommodate left and hand turning pumps. Using single spring mechanical seals allows flexibility to accommodate misalignment, any deflection of the shaft, and any form of breakaway shock loading. A single spring seal also has the capability to resist clogging even in the most extreme vicious conditions by containing different types of fluids. Single seals don’t always meet the shaft sealing requirements of today’s refinery and chemical application pumps due to the small amount of required. The seal industry has configurations that incorporate two sets of sealing faces with a clean barrier fluid injected between these two sets of seal face. The choice to choose between a double or single seal comes down to the initial cost to purchase the seal versus the cost of operation, maintenance, downtime caused by the seal, length or preventive maintenance cycles and the environmental and user plant emission standards for leakage from the seal.
