What Kind of Powders Can this Pump Handle?

Our Powder Diaphragm Pump is suitable for free-flowing, dry powders with a specific weight between 80 and 720 kg/m³. Typical powders include sintering powder, carbon black, silicones and resins. If the powder does not clump when squeezed by hand, the Tapflo Powder Pump is likely compatible.

How is it Different from Manual or Mechanical Powder Handling?

This pump provides a closed-loop, hermetically sealed system that reduces the risk of operator exposure, dust contamination as well as material loss. These pumps are more compact and cost-effective than large powder handling systems, while being portable, allowing for manoeuvrability and easy installation in various locations.

What is the Pump Housing & Wetted Material Made From?

The housing is constructed from PTFE-coated aluminium, offering excellent chemical resistance. Inlet/outlet is constructed from AISI 316L Stainless Steel, with diaphragms available in EPDM, NBR or PTFE, and the valve balls available in EPDM, NBR, AISI 316L, or polyurethane (PU).

Can this Pump be Used in ATEX Environments?

Yes. This pump is ATEX-certified for gas group IIG, dust group IID, and category 2 (zone 1).

How Does this Pump Prevent Contamination?

The powder is transferred via a fully sealed system with no open handling or manual scooping required. This minimises operator exposure and airborne dust release.

Is the Powder Capacity Consistent Across Applications?

No. The capacity is heavily dependent on the powder's properties, such as bulk density, particle size, flowability as well as compressibility. We'll help determine performance in your application based on material samples or specifications.

What Connection Sizes are Available?

We offer 3 different connection sizes based on model. The TXP120 model features a 1" BSP thread while the TXP220 features a 1 ½" BSP thread. Furthermore, our TXP420 model features a 2" BSP thread, offering versatility in application.

Powder Pump

Our TXP Powder Pump is an economical and compact alternative to many complex and large powder systems, and is designed to handle a range of industrial and sanitary process powders with specific weights from 80 - 720 kg/m³. Based on our standard Air Operated Diaphragm Pump, our ATEX-rated TXP Pump uses compressed air to drive 2 diaphragms, a design that prevents powder blockages. To ensure our Powder Pump is right for your application, a general rule is that if the powder does not clump together when squeezed in your hand, it can be used successfully. Due to the nature of powders, we will always trial a Powder Pump with your application first to ensure everything runs smoothly.

Typical applications for our Powder Pump:

  • Mining
  • Catalytic Converter Manufacturing
  • Medical Powder
  • Active Pharmaceutical Ingredients (APIs)
  • Frozen Food
  • Food Production
  • Icing Sugar
  • Brewery
  • Plastic Manufacturing

Overview

The innovative design of our Powder Pump not only means it can be portable, but also reduces the space requirement for powder transfer applications. The complexity and cost of installation, commissioning, and maintenance requirements are all reduced. The non-stick PTFE coating enables an efficient transfer through the pump with the least possible resistance.

What powders can our Powder Pump handle?

Our Powder Pump will handle different process powders, with specific weights from 80 to 720 kg/m³ dry weight. Generally, if the powder does not clump together when you squeeze it in your hand, the Tapflo Powder Transfer Pump can be used successfully. Examples of standard powders are sintering powder, carbon black, resins and silicones.

How does a Powder Pump work?

The TXP Powder Pump is hermetically transferred by means of the two diaphragms, which alternately prime the powder from the container in the first cycle and discharge to the process in the second cycle.
