Application Guide: Powder Pumps

Did you know a Powder Pump can handle more than just fluids? As its name would suggest, it’s designed for pumping various types of powder for transfer applications within both industrial and sanitary environments.

Based on the design of the air-operated diaphragm pump, this pump is compact and can be easily stored and transported.

The Powder Pump is a product from our air-operated Diaphragm Pump range that caters to diverse applications and industries, transporting a range of powders that don’t clump together when squeezed.

This pump is extremely economical due to its power-to-size ratio and solid construction with few components. This is achieved by a simplistic and compact design compared to other powder pumps.

Powder Pump

Powder Pumps are driven by compressed air to move diaphragms inside the pump housing. These diaphragms work simultaneously to trap the product in one side, whilst the other diaphragm forces the same volume of product out of the discharge port.

The pump then recycles air exiting the pump through the air exhaust, which is fed back into the pump by the valve balls, diffusing any powder that will collect here as the valve balls open and close.

The hematic transfer system, driven by the diaphragms, primes and discharges powder, ensuring the powder transfer is contamination-free and maintaining product integrity.

This FDA-approved pump is efficient for pharmaceutical, cosmetics and the food and beverage industries.

The Powder Pump can handle most types of process powders, considering the consistency is correct. To test this, hold a bit of powder in your hand and squeeze it. If the powder does not clump together, you can use our Powder Pumps.

Specifically, it will transfer powders from 80 to 720kg/m³ dry weight with a maximum solids size of up to 15mm.

Some examples of powders that can be pumped are:

• Sintering Powder
• Carbon Black
• Resins & Silicones

Please note, powders that clump together can cause blockages within your pump, causing it to fail. The consistency and weight of the powder you are pumping will determine the maximum capacity of your pump.

There are many benefits to using Tapflo Gulf’s Powder Diaphragm Pump, these include:

• Economical: Compared to bigger, complex systems, with 70% fewer parts than competitors’ models.
• Solid Construction: Manufactured from metal and a PTFE non-stick coating.
• Compact: Easily stored and transportable due to its small size.
• ATEX approved: Hazardous materials can be pumped if required.
• Self-priming: Can self-prime up to 5m from dry suction pipe
• Convenient: Safer than manual powder handling.
• FDA approved: The hemetic system ensures contamination-free transfer of the product.

Yes! A Sanitary Powder Pump has been developed for use in the pharmaceutical and food industries. For example, the pumps can handle powders such as icing sugar.

Sanitary Powder Diaphragm Pump

We recommend installing the Powder Pump below the powder tank, with a gradual feed of powder into the pump.

With a no-nut, clean-face diaphragm and a streamlined design featuring 70% fewer parts than competitors, maintenance is efficient and straightforward. Our pumps can be customised to suit specific requirements, whether on mobile or stationary trolleys or as part of a bespoke solution.
