![]() Bottom line – use as fat a pipe as possible and keep the pressure down! The friction loss difference between 2-inch and 4-inch can be massive and make or break a high viscosity pump project. The bigger the internal bore of your discharge pipework, the lower the resistance caused by friction losses. ![]() Size matters! Use large bore discharge pipe or hose. Using a pump with a large inlet and large internal cavities makes things easier by reducing resistance and overcoming bottlenecks…passing a camel through the eye of the needle is not easy! Running at low speeds not only protects shear-sensitive fluids or entrained sensitive solid particles but it also helps the pump to grab hold of the liquid and pump continuously without cavitating. Where a centrifugal pump is good on water or juice, it will not pump caramel or tomato paste! Kecol’s Viscous Pumps use Piston pumps for most of our high viscosity pump duties as they offer a partial vacuum to help suck the product into the pump, we can also use other pump types such as rotary lobe, twin-screw, progressive cavity or other pumps from our portfolio. You’re going to need a viscous pump that can handle the higher pressures required to move heavy, viscous fluids. ![]() Use the best pump for the jobįor high viscosity fluids you will need a really strong and powerful Viscous Pump. Here are some tips to look out for when choosing your Viscous Pumps. ![]()
