What a Drag Effects of Fluid Viscosity on Centrifugal Pumps

Nov 15, 20170183;32;A frequently stated expression around the pump industry is that viscosity is the Kryptonite of centrifugal pumps. Pardon the allusion to Superman, but it is a reference most of us not only relate to, but also understand. Further, viscous fluids do have a negative and weakening effect on centrifugal pump performance.

Heavy duty viscous fluid pumps. Applications involving the pumping of high viscosity fluids, for example viscous chemicals, adhesives, pastes and slurries, require specific types of pumps able to handle them. As the liquid passing through the pump internals is thick, certain technologies such as centrifugal pumps struggle due to frictional losses

Centrifugal Pumps and Influence from Viscosity

Centrifugal Pumps and Influence from Viscosity. When a liquid flow through a pump, hydrodynamic losses depends on fluid viscosity. Sponsored Links. When a more viscous fluid is handled by a centrifugal pump. brake horsepower requirement increases. the head generated is reduced.

For high viscosity fluids, centrifugal pumps are not ideal because of the close critical tolerances and lack of ability to mix thixotropic materials to provide a shear thinning effect. Without this thinning effect, the viscosity is not naturally reduced by the action of the pump, causing the pump to require more and more power as the viscosity is increased.

For instance, water has a low viscosity of 1 cSt at 20176;C, while motor oil has a high viscosity of more than 500 cSt at the same temperature. Viscosity is essentially resistance to flow and this has implications for pumps, says S248;ren Mortensen. If you have a highviscosity, sticky fluid on your hands, it clings and its much harder to remove than a lowviscosity fluid.

Jan 29, 20150183;32;Generally speaking, centrifugal pumps are most suitable for low viscosity fluids, since the pumping action generates high liquid shear. As viscosity increases, pump performance diminishes due to friction loss. Viscous drag imparts on the impeller, the pump's head and flow are reduced, and the horsepower required is increased.

A centrifugal pump is within the rotodynamic pump family. Rotodynamic pumps are kinetic machines in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller or rotor. The most common type of rotodynamic pump is the centrifugal (radial) type.

Sep 14, 20150183;32;Figure 2. External gear pumps (shown is a double pump) are typically used for highpressure applications such as hydraulics. External gear pumps are similar in pumping action to internal gear pumps in that two gears come into and out of mesh to produce flow (Figure 2).
