Eccentric Pumps is changing the way the hose pump industry thinks about pumping and metering. Since the heart of every peristaltic pump is the hose, we decided to create a pump with a mechanical design whose sole purpose is to promote long hose life. We accomplished this by eliminating the sliding friction of multiple shoes. Since friction builds heat, and heat is detrimental to hose life, the obvious solution was to change to a rolling element. Our large diameter roller provides a long sealing line so that the pump can build pressure without backflow. Additionally a small reservoir of our synthetic DST™ lubricant further reduces friction between the roller and the hose while efficiently dissipating heat away from the process. The next impediment to long hose life is the number of occlusions or hose pinches required to pump. A pump with four rollers or shoes will pinch the hose four times per revolution of the shaft. A pump with two shoes or rollers will pinch it twice per revolution. Because our pump incorporates an eccentric shaft with a single roller, our hose is compressed only once per revolution. Since hose pumps come in different shapes and sizes, the industry has introduced the P/100 ratio to make a fair and equal comparison of one pump to another. The P/100 ratio is the number of hose pinches required to displace 100 gallons of fluid. Our pump has the lowest P/100 ratio in the industry for an equivalently sized pump!
