Slurry & Oil Pump

RAAH International Slurry and oil pump

A wide range of ratios and models make our equipment suitable for every tractor or motor-pump assembly with sprinkler systems. Likewise, there are an extensive number of models and ratios to choose from when selecting a tractor or slurry pump.


Today’s FCC (fluid catalytic cracking) units rely on mechanical seals in their pumps. For these to work, the seals must be able to withstand high operating temperatures, and the shaft and its seals need to be cooled with a suitable fluid.

However, using large amounts of expensive rendering liquid can be expensive. The liquid passes through the throat bushing and into the less valued pumpage. Some applications of slurry pumps include:

  1. Ballast transfer
  2. Ballast water treatment systems
  3. Sea water service
  4. High temperature and low temperature feed to boilers
  5. Sea water and Fresh water cooling systems
  6. Farming and Aquaculture
  7. Transferring low solids content grey water
  8. Fuel transfer, including marine diesel
  9. Sea water injection
  10. Scrubber systems

Why use the right slurry pump?

A lubricant is needed to keep the pump working. Different oil types can be used for various purposes.

When it comes to slurry pumps, choosing the right lubricant for your bearing assembly can limit wear and shorten maintenance cycles. Using the wrong kind of lubricant in your operations could lead to a host of problems.

  1. Failing prematurely: Roller bearings are subjected to conditions that are tougher than other parts and do not handle low oil quality.
  2. Corrosion: Mixing incompatible oils can cause corrosion due to incompatible chemicals reacting.
  3. Extreme contamination: For slurry pumps, it’s important to choose a lubricant that has the time interval you need. Oil is also different depending on what it is used for.
  4. Temperature: Temperature intolerance is when a bearing can’t absorb much heat, and when oil would normally accomplish this. But without many variations in the temperature or being underwater, lubrication becomes even more necessary.
  5. Overheating: Extra oil or grease can lead to an overheated pump.

Available Models Based On Lubricants

Before using a pump, you should take into consideration the application. If it is slurry pumping, you should use heavy-duty lubrication and have strict maintenance on the bearing assembly. Learn about the three different types of lubricants

  1. Grease: If you are using a small, light load, grease may still work to lubricate the movement. But if you are applying grease to all other applications, dirt and contaminants will be too close to the moving pivots of the gears, making it difficult to apply enough oil.
  2. Mineral oils: Once upon a time, mineral oils were the industry standard for bearing assemblies. Nowadays, synthetic oils are better for certain circumstances. Mineral oils are still somewhat beneficial, though–they can offer acceptable service up to 180°F (82°C), in most cases.
  3. Synthetic oils: Synthetic oils provide higher film strength and temperature tolerance than premium, petroleum-based products during the commission and break-in periods while also having clear advantages when it comes to maintenance. An ISO 150 synthetic oil with a single viscosity grade is available for use in all pump sizes. For extremely cold conditions or underwater operations, you should use an ISO 100 synthetic oil.

Make sure you’re maintaining your pump properly, but also use the best oil to protect it.

Available Models

When you are deciding on your pump, remember that there are many variations available. Some pumps have features such as prime capability or orientation. You can contact us to help you find the right pump for your needs.

The Azcue MN range of horizontal centrifugal pumps is compact and can produce flow rates up to 500m³/hr and pressures up to 10 bar. Some of the models they provide parts for include the followimng features.

Top Features

This foundry can create centrifugal pumps that are a perfect fit for marine vessels in various materials. These pumps meet classification standards as well as international and domestic regulations.

Azcue produces pumps in various materials to suit a wide variety of applications, adhering to standards from classification bodies such as Lloyds and DNV.

Special versions with either electric (MN-EP Version) or air-powered (MN-VP Version) priming pumps to make a complete self-priming pump are available on request. MN series pumps with high-temperature seals and Atex versions for flammable fluids/environments can also be manufactured if required.

North Ridge Pumps have a great deal of experience supplying spare parts for Azcue pumps, below are some of the common models we supply spare parts and complete replacement pumps for.
