Tapflo Metal pumps
The compact, smooth and simple design is common for this series. Materials available are aluminium, cast iron, stainless steel and PTFE coated aluminium. You will discover the ingenious simplicity when you maintain the pump. We use approximately 70% fewer parts than our competitors use to build similar sized pumps.
ATEX Directive 94/9/EC Equipment intended and approved for safe operation in potentially explosive atmospheres. The equipment is divided in main groups, categories, apparatus groups and temperature classes to define its suitability in the actual zone.
Aluminium and cast iron pumps For transfer of pH-neutral fluids, both thin, thick, solid laden or abrasive. The aluminium and cast iron pumps are found in most fields; work shop and paint industries, purifying plants etc., to mention only a few. AISI 316 stainless steel pumps Made in lost wax cast method, ensuring great accuracy and finish. The stainless steel pumps combine great mechanical strength with good chemical features. AISI 316 is resistant to aggressive liquids like nitric acid and sodium hydroxide. The centre unit, which is not in contact with liquid, is made from corrosive resistant polypropylene (PP) as standard (other materials upon request). ATEX certified pumps All metal pumps are available in explosion proof ATEXmarked version. They are supplied with earth connection and conductive materials; conductive centre section (onAISI 316 pump), diaphragms in PTFE (conductive back) orEPDM (conductive).
1. Flexible installations The connections may be rotated 180°. Simply turn the connections to fit your piping system. Threaded BSP orNPT connections is standard. Twin connections are also available.
2. Powerful valveseats The valve seat is under constant stress from the movement of the valve ball. To obtain the best wear resistant, the integrated seat is made from AISI 316 stainless steel.
3. Low air consumption The air distribution system is designed with shortest possible air distribution ways. This eliminates "dead spaces", resulting in high effiencey and low air consumption.
