The Different Types of Centrifugal Pumps
In myriad industrial settings, fluids have to do more than lie idle in a reservoir. We put fluids to work throughout systems, and in order to get them moving, we rely on pumps to get the ball—or more accurately the water, or the solvent, or the slurry—rolling. When dealing with low-viscosity fluids that offer little resistance, a centrifugal pump is often the best variant for sending them through process piping and other systems. Unlike other models, centrifugal pumps use rotational energy to circulate their fluids. Within this broad category are several different types of centrifugal pumps, a few of which we’ll examine here.
This is a pump specialized for handling slurries, or fluids that contain suspended solids. Perhaps the best-known slurry is cement, which uses water as a medium for solid particles in order to shape and form the cement before it dries into place. Among its centrifugal counterparts, a slurry pump has to be tougher than the rest because the suspended solids it carries are often abrasive or corrosive. Other centrifugal pumps that aren’t optimized for this fluid would quickly wear down.
What we know as wastewater is scarcely only water. Along the way, it’s sure to pick up some heavy solids that could really gum up the works. To account for this, a grinder pump, also known as a chopper pump, comes equipped with teeth to chop and grind the solids that come through. These pumps are useful in household and commercial applications alike, dealing with solid wastes from kitchens, bathrooms, and washing machines, cutting them down to size before sending them further along.
The coolest centrifugal pump around, cryogenic pumps deal specifically with coolants and other super-cooled substances that would damage other centrifugal pumps not intended for such low temperatures. Cryogenic pumps mainly impel gases that have been cooled down into liquid phases, such as liquid nitrogen or liquid oxygen. You’ll find these in specialized industrial settings.
Magnetic Drive Pump
When preventing leakage is paramount, magnetic-drive centrifugal pumps distinguish themselves from the pack. Magnetic drive pumps are unique in that magnets couple the motor and the pump rather than a traditional mechanical shaft. Strong casing prevents the fluid—which could be caustic or volatile chemicals or simply water that must be kept away from electricity—from leaking.
