Choosing the correct sludge pump for your application in Australia can be challenging. Sludge or slurry pumps can be found in different industries and they play an important role in various processes. The main aspects to look for in choosing a proper sludge or slurry pump are the design, pump deployment, pump construction material and correct pump power sizing.

Pump design

The design of the pump is essential to ensuring that the abrasive and corrosive aspects of the sludge don’t destroy the impeller. Sludge may also contain large unforeseen solids that will clog most types of pumps. Most centrifugal pumps in Australia have got an impeller that has a close tolerance to the abrasive, volute and sometimes the corrosive nature of the sludge will ruin the tolerance and wear the volute. This will, in turn, cause the pump to lose suction capability. This can cause massive downtime with sludge or slurry pumps along with expensive spare parts and maintenance.

Construction material

When choosing a sludge or slurry pump in Australia, it is important to choose the proper material. If the sludge is highly abrasive then the best construction material for the pump is a Hi-chrome. This material has the highest hardness and it can withstand the abrasiveness of the sludge. On the other hand, if the sludge isn’t only abrasive but has a low pH, the best construction material should be duplex stainless steel. This material is the best for sludge pump in Australia to withstand caustic material that is highly acidic while maintaining a high Brinell level.

Deployment method

It is very important to determine the ideal deployment of the pump when determining the ideal setup. There are three main deployment methods which are flooded suction pumps, submersible pumps and self-priming pumps.

Flooded suction deployment

With this kind of deployment, the fluid is positioned above the pump. The pump is positioned below the fluid to be pumped and this makes it possible for the gravity to feed the fluid into the slurry pump’s suction and keep the slurry pump primed.

Submersible deployment

Slurry pumps that are submerged in the fluid are known as submersible pumps. There is no need for priming because the pump is completely submerged in the fluid.

Self-priming deployment

The pump and the power unit aren’t submerged. This means that the suction house goes into the sludge and the unit functions like a super-sized wet dry vacuum.

Pump seal

It is important to choose an ideal seal based on the abrasive nature of the sludge. A slurry pump seal is supposed to have hardness faces made from tungsten carbide or silicon carbide.

Pump power sizing

When choosing a sludge pump in Australia, it is crucial to determine the proper size and power requirements of the pump. Based on the abrasive nature of sludge, it is crucial to choose a size that will allow the pump to run at a slow speed to lengthen the duration of the pump’s life. The deal RPM to run the pump should be between 900 RPM and 1200 RPM.
