They are far from being ordinary liquids. They are sticky, slow, abrasive, and they require much more than just a simple pump. Pumps clog. Flow slows. Maintenance costs skyrocket. And if you\u2019re not using the right pump, the entire system can grind to a halt.<\/p>\n\n\n\n<p>High-viscosity fluids aren\u2019t just harder to move\u2014they demand precision-engineered solutions that most pumps simply can\u2019t handle. Choosing the wrong pump could mean unplanned downtime, excessive energy bills, or worse\u2014permanent equipment damage.<\/p>\n\n\n\n<p>That\u2019s when s come into play. For over 50 years, we have been helping various industries in the efficient movement of the toughest fluids with tremendous precision and reliability. Let\u2019s take you through what you need to pump thick fluids-sans the stress, clogs, and expensive blunders.<\/p>\n\n\n\n<p><strong>What Does \u201cViscosity\u201d Really Mean?<\/strong><\/p>\n\n\n\n<p>In moving liquids, the internal resistance to flow is called&nbsp;<strong>VISCOSITY.<\/strong><\/p>\n\n\n\n<p>Viscosity plays an important role when selecting Roto progressing cavity pumps.&nbsp; It is vital to the proper selection, and all efforts must be made to obtain accurate viscosity data during the sizing process.&nbsp; Viscosities of most liquids vary with changes in temperature. Pressure change, however, normally has no effect on viscosity of a fluid. In addition, viscosity of moving fluids can change depending upon the extent to which the liquid is agitated or sheared.<\/p>\n\n\n\n<p><strong>Meaning<\/strong>: Internal resistance to fluid motion. Flows in a fluid are temperature- and shear rate-dependent but not pressure-wise.<\/p>\n\n\n\n<p><strong>Types of Fluids:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Newtonian Fluids: Maintain constant viscosity, although agitated (e.g., water, mineral oil).<\/li>\n\n\n\n<li>Thixotropic Fluids: Exhibit decreased viscosity under shear (e.g., molasses, glue, paint).<\/li>\n\n\n\n<li>Dilatant Fluids: Increase in viscosity when sheared (e.g., candy compounds, clay slurries).<\/li>\n<\/ul>\n\n\n\n<p><strong>Examples of High-Viscosity Fluids:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Bitumen \u00a0 \u00a0 \u2022 Molasses \u00a0 \u00a0 \u2022 Adhesives \u00a0 \u00a0 \u2022 Sludge\u00a0 &amp; slurry \u00a0 \u00a0 \u2022 Tomato paste &amp; syrups<\/li>\n<\/ul>\n\n\n\n<p><strong>Viscosity Impact On Pump Selection<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>The more viscous a fluid is, slower the pump will have to run Thus giving more time for liquid to fill the cavity.<\/li>\n\n\n\n<li>Even at reduced speeds, the pump may not develop 100% volumetric efficiency and this must be accounted for in the selection process.<\/li>\n\n\n\n<li>Most fluids shear thin to a level well below their static viscosity. Hence pump speed and pump size should be selected as per the shear properties.<\/li>\n\n\n\n<li>\u00a0\u00a0Greater the viscosity, Greater will be the frictional power.<\/li>\n\n\n\n<li>\u00a0\u00a0For a range of viscosity, flow should be selected at the lowest viscosity and \u00a0 power should be checked at the highest viscosity<\/li>\n\n\n\n<li>\u00a0Viscosity is sensitive to change in temperature.\u00a0<\/li>\n\n\n\n<li>Viscosity at pumping temperature should always be considered during the pump selection<\/li>\n\n\n\n<li>\u00a0\u00a0Pumps are applied based on shear viscosity in a flow condition.\u00a0 Roto can provide shear rate testing free of charge.<\/li>\n<\/ul>\n\n\n\n<p><strong>What Kind of Pump Works Best?<\/strong><\/p>\n\n\n\n<p>Not all pumps are designed to meet the requirements of high viscous challenges. Many conventional models fail to cope with sticky, slow-moving, or abrasive fluids. Hence, the Progressive Cavity Pumps (PCP) are considered to be the best solution.<\/p>\n\n\n\n<p><strong>Why Roto PCPs are a better choice?<\/strong><\/p>\n\n\n\n<p>ROTO PCPs are specifically engineered to handle high-viscosity, abrasive, and shear-sensitive fluids. Our PCP unique rotor-stator mechanism delivers a smooth, non-pulsating flow, making them ideal for challenging applications like molasses, sludge, and heavy crude. Unlike conventional pumps, PCPs maintain consistent performance with minimal wear, even under tough conditions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Have you ever dealt with thick fluids like molasses, sludge, or heavy crude\u2014you know the struggle is real.
