Pumps and motors are vital across many industrial operations. They exist to move liquids through key areas of plants. This mainly involves supplying fluids or evacuating fluids to ensure effective and efficient operations.

Pumps come in various sizes and configuration, depending on the required application and industry. Industries, such as wastewater plants, mines and quarries, oil and gas refineries, and power generation plants all rely on pumps transferring fluids from one process area to another. Pumps are critical to many of the operations within all of these facilities.

Breakdowns in industrial pumps can be costly to your business. If a pump fails, everything can grind to a halt, especially when there are no redundant or backup systems in place. This can lead to significant downtime and costs while you replace or repair parts. Because of this, it’s vitally important to use proven solutions and to have the right parts and products to get your pumps back up and running as quickly as possible.

Having a strategy in place to optimize your industrial pump maintenance and repair is also vital. Part of this strategy should define who manages repairs and whether you use onsite trained and skilled engineers or outside contractors. This will largely depend on the size and nature of your operations, as both can impact your planning, costs, and downtime differently. 

Find the right products and pump repair and maintenance services to avoid failure and minimize pump-related downtime with LOCTITE®. We offer on-site expertise and a range of products designed to keep your pumps operating better for longer.

Pump Repair Challenges

Whatever your industry, pumps are at the heart of keeping things moving. Therefore, you need them to be functioning at their best at all times. Like all types of machinery, pumps will suffer wear over time which can cause downtime. This can be caused by abrasion, mechanical damage, or corrosion. Additionally, various internal and external factors can cause parts to fail, which leads to costly pump breakdowns.

Vibration and torsion, which are both part of the normal operating conditions of your pumps, can also lead to issues with shaft misalignment. This creates challenges in the effective operation of pump-motor installations and can severely reduce the mean time between failures (MTBF). For this reason, it is important to prevent common shaft misalignment causes during your centrifugal pump maintenance and ensure that you get the full operating life of your bearings and seals by maintaining proper shaft alignment. If you need to make a worn shaft repair, centrifugal pump volute repair, or perform a complete overhaul, our extensive LOCTITE® portfolio of pump repair products offer reliability and proven high-quality results.

Eliminating Loosening

Rotating movement is a key and basic operation of pumps. But this constant movement can cause problems with loosening of set screws, bolts, fitted components, and others. Without the right security in place, these components can loosen prematurely and have a direct negative effect on operational efficiency.

Vibration, impact, torsional stresses, and temperature fluctuations can all take their toll on different aspects of a pump, leading to loosening and cylindrical assembly failure. 

Threadlockers provide an effective solution to resist the effects of these forces. They secure multiple important parts within your pumps by preventing loosening, while ensuring clamp load is maintained.  They also prevent bolt seizure caused by corrosion.

Pump parts that are typically susceptible to loosening include:

  • Mounting bolts
  • Casing bolts
  • Adapter bolts
  • Set screws
  • Flange bolts

Preventing Threaded Fitting Leaks

As industrial pumps move liquids and other fluids from one place to another, leaks can be costly and lead to substantial downtime, or even cause safety issues within your plant.

Leaks within threaded fittings can cause a loss of lubricant or coolant, which can lead to catastrophic failure of a pump. Whether this is the lubricant within the power end or coolants for mechanical seals or glands, leaks within these fittings can be caused by vibrational loosening, installation errors, or an ineffective sealant being used. All of these causes can result in a critical component failure and ultimately prevent continuous operation of a pump.

LOCTITE® thread sealants work by effectively filling the spaces within threaded parts and provide an instant, low-pressure seal that prevents fluid leaks that can cause costly downtime. Seal threaded fittings to avoid costs and failures related to lubricant leaks.

Filling Mechanical Fitting Gaps

Mechanical fitting methods sometimes leave gaps between fitted parts, which may cause both flange assembly and cylindrical assembly failures. Pump flange gaskets can be made more reliable by filling gaps in flange surfaced with LOCTITE® flange sealants. LOCTITE® retaining compounds offer superior strength and gap filling capability with fast cure speeds for mounting bearings effectively and quickly to shafts or housings. Additionally, our range of LOCTITE® machine base grout products are non-shrinking epoxies that effectively fill pump mounting bases. These machine base grouts offer high compression strength to ensure a reliable and rigid base to reduce vibrations for optimal operation of your pump and motor assemblies. 

Reducing Corrosion

Different liquids coming into contact with metal casings and components in your pumps and temperature fluctuations can lead to a risk of corrosion. This includes both internal and external parts.

Most industrial pumps operate in harsh conditions. They’re often exposed to high humidity and moisture, high temperatures, and chemicals in both indoor and outdoor environments. All of these factors can promote corrosion and seizure of parts. 

Corrosion can affect many parts of a pump, including:

  • Pump bases
  • Gland assembly nuts
  • Jack bolts

Anti-seize compounds can protect your assemblies against seizure to such vital areas, which allows you to properly maintain your equipment.

Our LOCTITE® sprayable ceramic pump coatings and chemical resistant coatings protect the surface of pump exteriors and pump bases against chemical attack. Chemical attack and corrosion can quickly degrade these valuable assets.

Rebuilding Worn Elements

Slurry abrasion, cavitation, and general use over time can all cause wear within pumps. The cutwater within the pump volute is a common area of high wear and needs protection and oftentimes rebuilding.

Certain parts of your pumps are more susceptible to wear. These include the:

  • Volute
  • Shaft
  • Impeller

Reduce the effect of wear and protect these parts by applying protective pump coatings to impellers volutes before putting them to use and during pump overhauls and rebuilds.

Using retaining compounds to prevent bearing spinout and wear on shafts. Use LOCTITE® metal rebuilding compounds to repair worn shafts and restore them to their original dimensions.
