5 Ways to Maintain Mechanical Seals
The often-forgotten and crucial component in a pump system is the mechanical seal, which prevents fluid from leaking into the immediate environment. Leaking mechanical seals due to improper maintenance or higher-than-expected operating conditions can be a hazard, housekeeping issue, health concern, or even an EPA issue. It is important to implement practices and conditions to ensure the proper operation and longevity of your mechanical seals to prevent leakage and subsequent downtime or safety hazards.
Here are some things that you can do to ensure a longer life for your pump seal:
1. Understand your Conditions
Pressure, temperature, and speed are all factors that can contribute to a worn seal or increased leakage rate. Knowing the application conditions will help better select the right mechanical seal. The mechanical seal may perform steadily in fixed application conditions, however, if system variables are introduced, they may have drastic effects that can reduce your seal&#;s durability. The published limits a seal can withstand are more accurate for a continuous operation where there are more constant conditions. These limits are not as precise with a cyclic operation.
Combining process variables creates varying degrees of conditions that a seal may need to adjust for such as vaporization, freezing, or extreme heat that needs to be dissipated. Applications that operate under higher pressures, higher temperatures, faster speeds, and thicker pumped fluid makes maintaining a pump&#;s efficiency more difficult. Having a mechanical seal that is more robust and resistant to condition changes may be the key to keeping repair downtime at a minimum if you have a more difficult fluid transferring process.
2. Know Seal Face durability with Liquid
The fluid being pumped is in most cases is the lubricant for the mechanical seal. The fluids, depending on the application, are susceptible to temperature and pressure changes. Similar to the condition factors, the liquid is the main variable, with vast degrees of physical and chemical states that need to be understood. Liquids can range in thickness, purity, volatility, toxicity, and can even be explosive depending on the temperatures, pressure, and chemical compatibility.
Greater seal face pressure and deflection capabilities decrease the chances of having to replace or repair the seal. Lowering the damage sensitivity can be obtained by selecting the right combinations. Hard/Hard mechanical seal faces are better for dirty fluids, but vulnerable to higher damage if the fluid film is lost. Hard/soft mechanical seal faces can hold up longer after periods of lost fluid film before seal faces become damaged. It is important to understand the limits that the pump system will be exposed to based on the application, and how that will affect the liquids state along with how that seal can sustain expected performance.
3. Know the reason for Seal Face Wear
Excessive leakage is typically a symptom of a worn seal face. There can be other more serious issues with your pump, such as bad bearings or a bent shaft.
If worn from abrasive contact, the rubbing edge of the seal will show signs of physical distress such as grooves and even chips. Some seals also need a flushing system to remove the heat that is developed. Serious issues may occur if this process is interrupted or stopped.
4. Reduce Vibration
Try to operate your pump in its BEP (Best Efficiency Point). When you deviate from this it can cause pump cavitation This will cause vibration which can deteriorate the seal. Operating at maximum flow can be deadly to the pump.
Excessive vibration can cause deterioration of components within the seal such as the O-rings, bellows, polymer or wedges, or metal parts such as springs, drive pins, or set screws.
5. Proper Lubrication
Mechanical seals rely on the fluid film between the seal faces to reduce heat and friction. The fluid being pumped in most cases provides this lubrication as it comes into contact with the seal faces. Maintain your seal by not operating in a dry run. Install a Dry Run Monitor or flow sensor that will alert users when there is not sufficient fluid within the system. Continuous applications tend to be more stable with mechanical seal reliability than cyclic applications for this exact reason.
Mechanical seals on average are rated to last a minimum of a span of two years. Obviously as stated earlier this is largely dependent on the variables, conditions involved, and the limits to which you run at. Knowing your system and how it will function and what to look for when problems occur can go a long way in maintaining a mechanical seal. Selecting the right one can be a time-consuming and complicated process, Anderson Process has the knowledgeable experts to help guide you towards providing a solution that helps your system perform at maximum efficiency.
The life-span of engine oil seal
The life-span of engine oil seal
What is the normal life-span of an engine oil seal?In view of constant heat from the engine, the rubber oil seal will becomes harden/brittle and start leaking oil.
Should we wait until it leak oil before pulling the engine to change it or should we change it on a regular basis like every 50,000 miles or every 5 years?

Re: The life-span of engine oil seal
don't put any oil in your engine and the seals will *never* leak...Re: The life-span of engine oil seal
Seals don't wear out, they fail.Treat it the same way you treat the front window or any light bulb. Replace when failed.
Re: The life-span of engine oil seal
Its kinda more of a 50-50 thing. Its more of an issue of the seal wearing out than hardening. Under normal conditions seals like the rear main should last for quite a while. Also one more thing to consider when replacing a wear item is to check for any additional wear. Usually where the seal lip rides on the crank. You will find a groove worn on the end of the crank. When this happens you have several options. First option if you are lucky they offer a wear sleeve. This will fit over the end of the crank and give you a quick fresh surface and you can continue on. If not then you are faced with either having your crank turned or looking for a replacement. But that being said personally I wouldnt mess with anything until absolutly necessary. And remember vw's dont leak, they mark their territory!Re: The life-span of engine oil seal
If one is old and hard, you can be more are too. I recently replaces the flywheel seal and O-ring, I replaced these while I was at it.Re: The life-span of engine oil seal
My usual method is to check any oil seals anytime I have them exposed (timing belts or clutches on watercooled cars) and if they show signs of being anything but the soft, pliable sealing plastic they're supposed to be I replace them. Easier to do it while the engine is already out than to have to pull it again!Since the cam, crank and intermediate shaft seals are identical on a WCVW inline four, I have a good stockpile of them already, all good OE seals rather than reboxed FLAPS seals. I keep a smaller stock of crank rear mains and the carrier gaskets.

A "speedi-sleeve" fix might work, if one were available - but I've never heard of one for the VW flywheel.
Sagaboy's flywheel shows some pretty serious pitting, personally I'd replace it if I was hoping to be totally leak-free. If that's not in the cards, I'd polish it with emery cloth and use an orange hi-silicon seal. Preferably a double-lip, but if only a single-lip could be found I'd put it in at a different depth than the old one (i.e., if the old one was only flush with the case surface put the new one in until it bottoms in the bore - or vise-versa) and cross my fingers.
The oil on the clutch disk got there by bypassing the O-ring seal inside the flywheel snout. That must be replaced, a new flywheel seal alone won't fix that problem.
