Choosing the best sludge pump Sydney for your application can be a very difficult task. Slurry pumps can be found in nearly all industries and play a very important role in numerous processes. When determining the right slurry pump for your application, you should consider the construction material, the pump design, the deployment of the pump and the correct sizing.
Pump design
The pump design is critical to ensuring that the corrosive and abrasive aspects of the slurry don’t destroy the impeller of the pump. Sludge and slurry may contain large solids that will clog critical parts of the pump. Since most centrifugal slurry pumps have an impeller that has tolerance to the volute, the slurry’s corrosive nature will wear the volute and damage the tolerance. This causes the pump to lose the suction capability which leads to massive downtime with the pump along with costly maintenance costs.
For this reason, it is ideal to choose a pump that does not have an impeller. Choose a pump that has a rotor that doesn’t have critical tolerances.
Construction material
Choosing the right construction material for your pump is a critical process for determining the right slurry pump. If the slurry is abrasive with a neutral PH, the best construction material to use is a Hi-chrome which has the highest Brignell hardness that is capable of withstanding the abrasive nature of sludge.
If the sludge isn’t abrasive but has a low pH then it is best to choose a duplex stainless steel material. Choose your pump from a reputable sludge pump company that uses the right material that can withstand caustic material.
Deployment method of the slurry pump
When choosing the right slurry pump for your application, it is important to determine the right deployment method for your pump. The three main deployment methods are flooded suction pumps, submersible slurry pumps and self-priming slurry pumps.
Flooded suction deployment involves the fluid being positioned above the slurry pump. The slurry pump is positioned below the fluid so that gravity can feed the fluid into the pump and keep the pump primed at all times.
Submersible deployment involves pumps being completely submerged in the liquid. By being submerged, there is no need to prime the pump.
Self-priming deployment involves the power unit and the pump installed above the fluid and the suction hose of the pump goes into the sludge and the unit acts like a big wet dry vacuum.
Slurry pump seal
It is important to choose the right seal based on the abrasive nature of the sludge. A slurry pump seal should have faces made from either tungsten carbide or silicon carbide to ensure they are hardened. Some manufacturers incorporate a seal technology that uses a dual mechanical seal setup that allows the seal faces to cool at all times to avoid overheating.
Power sizing
When choosing a sludge pump Sydney, it is essential to consider the power sizing of the pump. Determining the right size and power requirement for your application is very important.
