How to Select and Use a Tapflo Powder Pump

Powder Pump

Tapflo’s TP Powder Pump is a type of Diaphragm Pump with a PTFE coating that ensures the pump can efficiently transfer powders. Benefits of using a Tapflo Powder Pump Powder Pumps are 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

  • PTFE coated aluminium pumps
  • AISI316L suction and discharge manifolds
  • Air induction system

How does a Powder Pump work?

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.

How does a Powder Pump work?The air induction system includes:

  1. Process powder
  2. Valve ball
  3. Diaphragm
  4. Non-return valve
  5. Needle valve
  6. Air induction line

What powder can be pumped? Our Powder Pump will handle different types of process powders:

  • Specific weight from 80 up to 720 kg/m3 dry weight.
  • Non hygroscopic

A few examples of common powders are:

  • Sintering powder
  • Carbon black
  • Resins
  • Silicones.

A general test that we recommend is to squeeze the powder in your fist, if the powder clumps together, it isn’t suitable for this pump.
