Industrial Pumps

It can be very difficult to choose between a positive displacement pump and a centrifugal one. The differences between these pumps are often not that clear. In this article, we take a closer look at the way positive displacement (PD) pumps operate, the unique characteristics of   positive displacement chemical pumps   and when to use them– making the choice ever so much easier. How does a positive displacement pump work? A positive displacement pump moves a trapped liquid from the inlet to the discharge pipe. By creating flow, this produces pressure. Because they can transfer highly viscous fluids at high pressure and low flow rates, the efficiency of PD pumps are not compromised or affected by this pressure. Read Original Post  Here...

Viscosity in pumped fluids can cause issues with all kinds of pumps, not least a centrifugal pump.   Plant Services   calls it the “great bugaboo of the industry”. One thing all centrifugal pump suppliers in Canada can all agree on is this type of pump isn’t a great choice for viscosities above 100 centipoise (cP), let alone 300. This calls for a positive displacement pump, usually one that is self-priming. To put this into perspective, the viscosity of honey at 25 degrees is 2,000 cP. According to  Pumps and Systems , viscosity measures the resistance of the fluid to flow at a given temperature. Think of it as fluid friction – or the fluid’s resistance to being pumped.

Magnetic drive pumps (mag-drive pumps) are seal-less pumps usually used in applications that are hard to seal and/or where leakage is a threat to people or the environment. Many industries install mag-drive pumps to avoid downtime for seal issues, or to prevent costly leakage of an expensive pumped fluid. A centrifugal mag-drive pump consists of a drive and driven magnet separated by a containment canister. This sealed containment canister prevents contamination of chemicals due to heat or air exposure that could cause crystallization, sticking and/or varnishing. Read Original Post Here...
