Pumps and motors are vital across many industrial operations. They exist to move liquids through key areas of plants, introducing the energy required to create the optimal flow. This mainly involves transporting fluids from a low to a high level, or low-pressure to high-pressure area. 

Pumps can be powered by different energy sources and come in various sizes, depending on the required application and industry. All industries need to move water, oil, chemicals, and various other fluids, transferring them from containers to drums, tanks, and other sources. 

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 while you replace or repair parts. So it’s vitally important 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 pump maintenance and repair is also vital. Part of this should define who manages repairs and whether you use onsite trained and skilled engineers or 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 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.

Types of Industrial Pump

Pumps streamline processes involving fluid movement without the need for human intervention. Common types found in most plants include:

  • Centrifugal pumps – performing multiple functions and used across most industries, including food  processing and chemical plants.  
  • Lobe pump – common in the pharmaceutical and food industries, these handle small solids, pastes, and liquids with high sanitary conditions.  
  • Piston  pump – reciprocating pumps used within heavy industry to pressurize fluid so it moves in the desired direction to power machinery. 
  • Drum pump – used to dispense chemicals safely, such as oil, acids, and sanitizers from bulk containers. 
  • Diaphragm pump – works with pressure and flow rate changes to offer flexibility for metering, spraying, and filtering water, or as a vacuum pump in the chemical industry. 

Pump Repair Challenges

Whatever your industry, pumps are at the heart of keeping things moving. So, 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. In addition, various internal and external factors can cause parts to fail, which leads to costly pump breakdowns. 

Vibration and torsion, which is part of the normal operating conditions of your pumps, can also lead to an issue with shaft misalignment. This creates challenges for the maintenance of pump-motor installations and can severely reduce the mean time between failures (MTBF). 

Applying threadlockers provides an easy solution to this common problem, eliminating loosening caused by vibration and removing the risk of shaft misalignment.

To keep your pumps working properly and your operation running efficiently, LOCTITE® industrial pump repair and maintenance is your ideal partner.

LOCTITE® Pump Repair Products

Knowing how to carry out repair and maintenance on your pumps is vital for maximizing uptime. But it all starts with knowing where the most likely pump breakdowns are, what parts of your pump are susceptible to these, and ensuring you have the right product for the job.

Eliminating Loosening

Movement is key to the operation of pumps. But this can cause problems with loosening. Screws, bolts, and any other components designed to hold everything together and maximize operational efficiency can work themselves loose over time without the right security in place. 

Vibration, misalignment, stress, and pressure can all take their toll on different aspects of a pump, leading to loosening and cylindrical assembly failure.  

Threadlockers provide an effective solution to this problem. They secure multiple important parts within your pumps to prevent loosening, sealing threaded assemblies to eliminate loosening caused by vibrations.

Pump parts that are typically susceptible to loosening include: 

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

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 drop in the volume of fluid running through a pump, which can lead to inefficiency and incorrect operation. Vibration, installation errors, wear and tear, and faults can all result in leaks within pumps. 

Thread sealants work to fill the space between threaded parts and provide an instant, low-pressure seal that prevents fluid and gas leaks that can cause costly downtime. Seal threaded fittings to avoid gaps appearing.


Filling Mechanical Fitting Gaps

Mechanical fitting methods sometimes leave gaps between fitted parts, which may cause cylindrical assembly failure and lead to leaks. Retaining compounds offer superior gap filling with fast cure speeds to make quick and effective pump repairs should your pump spring a leak. 

Reducing Corrosion

Different liquids coming into contact with metal casings and components in your pumps can lead to a risk of corrosion. This includes both internal and external parts, especially when leaks may occur. 

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

Corrosion can affect many parts of a pump, including:

  • Gland assembly nuts
  • Impeller shaft
  • Casing and adapter bolts

Anti-seize compounds can protect your assemblies against seizure to such vital areas, which allows you to properly maintain your equipment, while threadlockers can seal against fluids to further prevent parts from corroding. These are both essential to prevent air and fluids from damaging vital pump components.


Rebuilding Worn Elements

Resistance, abrasion and general use over time can all cause wear within pumps. Factors such as corrosion, pressure, and misalignment can make parts and components wear down faster. 

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

  • Volute
  • Shaft
  • Impeller

Reduce the impact of wear and protect these parts by applying protective coatings to volutes before putting them to use.

Retaining compounds can also help reduce wear by unitizing the assembly and providing uniform stress distribution.


Resisting Temperature Damage

The movement and energy generated by pumps introduces heat into the system. Alongside vibration and pressure, this can cause component failure within your pumps, leading to unplanned downtime. 

Thermal growth can also cause problems. Part of the normal operating conditions of a pump, thermal growth occurs when pumps heat up as they start operating because they’re pumping round hot fluids, are close to a boiler, or within a warm environment. These naturally hot conditions can cause fasteners to loosen, especially mounting bolts, which may lead to misalignment.  

Where metal parts are in direct contact, heat can spread quickly. So, temperature control is an important consideration. 

LOCTITE® gasketing sealant solutions ensure high-temperature resistance in pumps while sealing against fluid intrusion and leaks. This enables parts to withstand any vibration and pressure too. So, you can keep pump processes running smoothly, cutting the chance of failure and breakdowns.
