Tapflo’s TP powder pump is a type of Diaphragm Pump with a PTFE coating that ensures the pump can efficiently transfer powders. The benefits of using Tapflo Powder Pumps includes them being highly economical compared with other complex powder systems, such as Conveyer and vacuum systems.
These pumps are also convenient and safer compared to manual powder handling. In fact, no dust and no labour are involved. There are several standard powder pump execution:
The TP Powder Pump works like a standard Diaphragm Pump, using compressed air to drive the two diaphragms inside the pump.
These diaphragms work together, as one traps a set volume of liquid, the other pushes the same volume of liquid through the outlet port. In Tapflo’s TP Pumps, the air is then recycled back into the pump to dislodge any powder trapped around the ball valve. This prevents blockages in the pump that would be caused by a build-up of powder.
The air induction system includes:
Our Powder Pump can handle different types of process powders including 80 up to 720 kg/m3 dry weight and Non-hygroscopic powders.
Useful Tip! A general test that we recommend is to squeeze the powder in your fist, if the powder clumps together, your application isn’t suitable for this pump. However, if this is the case, Tapflo will still be able to provide you with an alternative solution from our extensive pump range!
Application Examples
Mining: Pumping powder waste into bags or replacing belt conveyor
Catalytic converter manufacturer: Catalytic powder to mixing pot; using the load cell for batch control; pumping directly out of 200 l drum; using flexible hose; stainless steel suction lance.
Medical Powder: dosing with load cell
Frozen Food: powder transfer in frozen food manufacturing; transfer of herbs and spices.
Icing Sugar: An unusual application, but pumping icing sugar is a powder that would require to be ATEX rated due to the increased risk of explosions caused by small dust particles that can form in the air.
