• The Tapflo powder transfer diaphragm pump is aneconomical and compact solution. It can do the same job as many complex and large powder systems. The compact design also makes the unit portable. The powder transfer pumps are modified from the standard PTFE coated aluminium series. The PTFE coating enables an efficient transfer through the pump, with least possible resistance. What kind of powders? The powder transfer pump will handle different types of process powders, with specific weight from 80 up 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. A few examples of common powders are sintering powder, carbon black, resins and silicones. Capacity The capacity of the powder transfer is extremely different from one powder to another, depending on the consistency and weight etc. Fore more specific information about the capacity in your application, please contact your local Tapflo distributor or fill out our inquiry form here. How it works The powder transfer pump is based on a standard Tapflo air operated diaphragm pump. The powder is transferred by means of two diaphragms, which alternately prime the powder from the container in the first cycle and discharge to the process in the second cycle. The powder is transferred in a hermetic system from the powder container to your process. No start up problems The air induction system eliminates powder pack up problems when starting the pump. Air is induced to the powder side of the pump for diffusion of the powder. The induction flow can manually be adjusted by means of a needle valve to obtain a optimum performance. Safe in EX-zones The powder transfer pumps are ATEX marked, allowing use in explosion hazardous zones (group IIG/IID, category 2). TXP220 is the smallest pump in our range of powder transfer pumps with a max capacity of approx 20 kg/min. TXP420 is the biggest pump in the range of powder transfer pumps with a max capacity of approx 30 kg/min.
