Getting A Seal Of Approval

Getting A Seal Of Approval

What Are Slurry Seals?

Slurry seals are an implementation of a substance which is comprised of a composition of water, clusters of small and mashed up rocks, asphalt mixture, as well as other preservatives.

These slurry seals are designed for roadway surfaces.

The reason it is used is to seal the road.

What this means is that by slurry sealing the surface, it is a coat of protection which essentially ensures a fresh road to drive on.

The roads chosen for such a technique are roads which have very little maintenance needs, and that which is not severely damaged.

Slurry seals are used to shut the cracks on the road, while also reimposing the pliability of the roadway surface.

What this also does is actually conserve the foundation of the road.

Slurry seals are can be applied on a regular basis (usually every five to seven years) or on an irregular cycle.

This is all dependent on things such as the level of traffic in the area, the area itself, the weather in the space, as well as the condition of the road.

Due to the fact that slurry seals set after a number of hours, it is usually used in parking areas, as well as places with a low traffic percentage.

Benefits of Slurry Seal:

  •             Minimises Oxidation
  •             Correct the damages
  • Enhancing the beauty of the road
  • Skid resistance
  • Minimising the ease of access of water

First Seal provides this service with reliability and effectiveness.

What is Gland Packing?

Gland packing is a process which uses string, soaked in a type of blubber or in a kind of grease.

When placed around a revolving handle, the gland packing seal will ensure that there are no leakages.

An example of this type of seal is found in a tap.

A faucet uses gland packing technology to form a sort of adhesive which will guarantee that no water is able to escape.

On a centrifugal pump, the gland is used similarly, however it is administered in a way which will ensure no leakages for a device which is used for a much longer period of time.

Double-acting steam pistons, hand pumps and wind pumps all use the gland packing technique.

Gland packing, as well as mechanical seals, are vital pieces of pumps and shafts.

A large part of the engineering components needs these gland pieces in order for their functions to work at an optimum level.

Although gland packing is a reliable and efficient form of decreasing or nullifying water leakages, the amount of maintenance which is needed to keep the system running well, as well as the cost of maintenance, could be something which detracts certain engineers or engineering companies.

These glands need to also be almost constantly lubricated, as with the gland packing process there could be leaks if it is not.

Abrasive liquids are also detrimental to the length of how long the gland packing can last for.

This means that corrosion can occur, leaving you now having to replace the glands which cost money and may also increase downtime.

However, such packing can actually outlive the seals on the system and have been known to cope with tough liquids.

Another plus is that gland packing allows for an easy to maintain the item, where seals make it a lot more of a challenge to fix.

The reason for this is that the pump will not be able to perform its task, therefore it will stop being used, while it is being dealt with.

Gland Packing Versus Mechanical Seals

It’s not to say that gland packing is better or worse than mechanical seals, it’s simply that they have different strengths and weaknesses, but both serve good and vital services for pumps and shafts.

Without the two systems, many engineering plants and machines would not be able to fulfil their purpose.

Choosing one or the other depends entirely on your financial estimate, as well as your ability to have it maintained.

Depending on what your system is doing could mean that a seal or packing is the better option.

This is because, for example, gland packing works better than seals in spaces within a space that has corrosive tendencies.

Seals would start to whither quickly in this environment, requiring you to replace and fix the shafts or pumps more frequently.

Gland Packing

Where it is effective, gland packing is also a method which requires costly repairs.

Packing is also susceptible to sprouting leaks with liquid or gas systems.

Lubricating needs to be done a lot so that leakages don’t occur, meaning that maintenance is not only costly, but it is also time-consuming.

Although gland packing works well in corrosive conditions, the length of time that the system will last for will be severely decreased.

It’s not all bad though.

There are situations where gland packing is more efficient than mechanical seals, as mentioned above, in the case of aggressive fluids.

Practices that utilise ball valves as well as valve clocks, globes and gate, work better for gland packing over mechanical seals.

Reciprocating pumps is a system which stores a large volume of liquid, and is released using pressure. An example of reciprocating pumps is a bicycle pump.

The gland packing style is used in a reciprocating pump as it is more effective than mechanical seals in this system.

Mechanical Seals

Mechanical sealing is the favoured type of system used by engineering processes.

Far more engineering applications use mechanical seals because it causes fewer issues in terms of leaks.

All in all mechanical seals require a very low amount of maintenance.

Seals also help with reducing your energy consumption, which can help in keeping costs low.

While keeping costs lower, mechanical seals also provide more efficiency in terms of time and effort.

Mechanical seals are not without their faults though.

Due to the pressure and temperature levels being funnelled through space, including accidental dry running, seals can begin to become worn out and will start to degenerate faster.

The prices of mechanical seals are also much more than gland packing.

Mechanical Seals or Gland Packing?

The question is not really which one is better than the other, it’s more so which one will work best for you?

Choosing either mechanical seals or gland packing will all depend on what type of system you have. Doing your research will allow you to understand exactly what you need.

Knowing which one will provide you with the best quality service, as well as give you little to no hassles, will save your business time and money.

Why Do We Need These Items

Not having pumps or other systems sealed can cause a lot of damage and can even lead to death.

With certain chemical gases being pushed through these pumps, the last thing you would want is for huge amounts of the gas, or even liquids, leaking out into the work area and causing health concerns for your staff.

Mechanical seals or gland packing stop these types of incidents from happening.

First Seal, Controlled Liquid Systems

Gland Packing

Everything has a time limit and once the limit is up you will need to replace it.

Gland packing is something which requires repairs where liquid or gas compartments are used.

First Seal provides a whole host of different packing items to meet their client’s demands.

Company Buying

Among all of the above-mentioned services, First Seal also provides a service which will attend to the day to day purchases of any products your company needs.

Cartridge Seals

Cartridge seals are also another alternative to use for your systems.

These cartridge seals are actually an item which contains a shaft sleeve, a seal, and a gland layer.

This item is then placed onto a pump shaft and no other fittings are needed for the pump to begin operating.

The only issue is that the pump and pump shaft needs to be in tip-top shape and space needs to be very compact for the cartridge seal to work.

However, when it works it is a luxury to be able to conveniently use your pump.
