The question often raised when a purchaser or a user decides to purchase a new pump, agitator or another type of rotating appliance is “how long will it take to run my appliance before it has to be taken down for maintenance?” In some cases, a user may consider upgrading their existing pumps to improve their reliability, capacity, effectiveness, or compliance. Normally, the question is the same.

The Metal Wiper Seals are targeted as the most critical component in many industrial pump applications. Due to an unacceptable leak rate or in some cases a level or pressure alarm, the pump is usually removed from service by the seal is often to blame for the failure of the equipment, but typically real reasons are in the operation and mechanical status of the pump or environmental inspection system for the Trisun Mechanical Seals.

The average life span of the pump is up to three years or more for companies which have implemented successfully and have therefore reduced their pump life cycle cost. LCC pump projections may vary widely on the basis of Hydraulic Cylinder Piston Seals. When the risk of failure is high, expert advice should be sought because life estimates errors can have costly consequences.

Any screening must be based on an understanding of the factors that drive the Metal Wiper Seals’ performance. The leakage rate and power consumption are normally the main performance indicators of a mechanical seal.

The Key Components

Mechanical seal faces are similar to covers. The main difference is the lubricant usually contains the pumped liquid itself and can, at pressures and at high temperatures, be dirty, volatile, viscous, toxic or explosive.

The sealing face is obvious, but other elements like the secondary dyeing elements (O-rings, bellows, polymer wedges), or metal components such as springs, pins or fitted screws also can influence the life of the Hydraulic Cylinder Piston Seals if it is subject to excessive or high temperatures and pressures. The screens are also the most vulnerable components of any mechanical seal.

The Seal Face Wear

It is first necessary because the faces have worn completely, to know that seals seldom exaggerate. If this happens, the narrower two facets will have been wearied in such a way that contact was lost and a leak path was created to escape the fluid into the atmosphere. Normal wear rates of Trisun Mechanical Seal faces are indeed extremely low and therefore do not represent a typical cause of excessive leakage.

Crash, blistering, chipping, grooving, thermal shock cracking are common symptoms of distress. The exception is wear-out seal removals, since in such cases, most likely, the equipment was removed for some other reasons that were not related to Metal Wiper Seal or just for preventive maintenance purposes. The symptom, i.e. visible evidence of a deeper problem in the device, processor control system, is a frequent over-mechanical leakage.

Seal failure types

Random failures tend to occur after a long period of time rather unexpectedly, characterized typically by quick shifts in the leakage behaviour of the seal from normal to excessive. This could occur as a change of the unvisible leak rate into a drip, or a steady drop, into a small stream of leaks.
