Description: A hose pump of the latest design includes Tapflo PT, combining the best materials with smart design solutions in order to maximise running time and minimise service. Principle of operation: the pumping action in Tapflo hose pumps is achieved by pinching a circular loop of rubber tube with two diametrically opposed rotating wedges. Due to the rotational movement, the fluid in the tubes is pushed ahead of each wedge. When each wedge reaches the end of the loop, the hose is released and the wedge rotates on to the start of the loop to begin a new cycle. As the wedge releases the reinforced tube, it immediately returns to its original shape, there by ensuring positive suction and priming. This construction makes it a smart and effective choice for a wide range of pump applications. Advantages: particularly suited to abrasive, corrosive, shear sensitive or viscous fluids; self-priming up to 9 m manometric lift; hoses reinforced with four layers of polyamide doubles the life time of the hose; drive of the pump independent of the pumping system, eliminates risk of liquid in the drive; easy maintenance, minimum of service time and a more economical pump solution; precise volumetric flow; continuous run dry capability without damage; reversive pumping action; high discharge pressure - 0-15 bar; and easy maintenance (the hose is the only wearing part). Typical applications: industrial waste water, waste sludge treatment, flocculent dispersions, flocculated waste, lime liquor, sludge and slurries, ceramic slips and paste, clay suspension and compounds, cement slurries, concrete pumping, ore slurries and leaching pulp as well as pharmaceuticals. The pump housing is partially filled with lubricant, thereby allowing smooth running of the wedges on the tube.
