Description

WHAT MAKES THE PE & PTFE PUMP DIFFERENT

The Tapflo (Polyethylene) PE & PTFE Air Operated Double Diaphragm Pumps are machined from solid block and are suitable for handling any kind of liquid whether it is viscous, chemically aggressive or containing abrasive solids.

Thanks to Tapflo’s innovative, simple & ingenious design these pumps are compact, robust & reliable. Furthermore, they are quick & easy to maintain, keeping your service costs and process down time to an absolute minimum.

When PE & PTFE used in conjunction with Tapflo’s patented control and monitoring equipment, preventive and routine maintenance is also easily integrated into any process, whilst also enabling accurate and precise control of the pump’s performance. Optimising your system to the best of its ability!

* = Recommended flow is half of the max flow, i.e. recommended flow for a T100 is 50 l/min

** = The value is based on pumps with EPDM diaphragms. Pumps with PTFE diaphragms produce approx. 15% less volume

*** = This is max value with stainless steel valve balls, other valve ball materials may reduce the suction.
