Life depends on pumps. The human heart is a pump that drives the blood that flows in our body destined to all muscles that need the nutrients and oxygen carried by blood cells. The same thing goes with big manufacturing plants; they need pumps to circulate the flow of fluids to arrive at certain process destinations.
The basic industrial pumps systems are water pumps systems. Water is the most common and abundant solvent that is used in most chemical and industrial processes. They are used to drive the flow of water in one direction. Water pump systems are mostly used in cooling or heating systems in industrial plants. The pumps can be fixed in place. They can also be mobile or handheld. One of these handheld or mobile pumps is the submersible pumps. This type of pump is submerged in a liquid that is to be suctioned out. Depending on the usage, the pumps can be made from cast iron, plastic or stainless steel. There are varying types of pumps depending on the application.
Sand pumps are special type of pumps that is used in slurries which contain a mixture of water and sand particles. Most sand pumps are centrifugal pumps used to separate the sand particles from the slurry. It is also used in “sand & filter” system filtrations. In the sand and filter system, the slurry of fluid and sand is pump through a series of filters which then captures the sand. The accumulated and compacted sand also helps in the filtration of smaller particles.
Gravel pumps are mostly used for dredging. Gravel pumps are designed for continuous pumping of slurries with wide particle size distribution.
One type of pump wherein the hydraulic fluid or air doesn’t come in contact with the fluid that is to be pumped is the diaphragm air pump. Diaphragm air pumps use reciprocating action of a flexible membrane, coupled with one direction flow valves to pump the fluid. This type of pump is ideal for medical purpose. This can be used in pumping blood, plasma or any other fluid that needs to be free from contaminant.
Selecting the ideal pump for your personal or industrial use can be tough. You will have to consider the type of fluid that you will be pumping. Most fluids vary in viscosity. Fluid viscosity can affect the power of the pump. High viscosity fluids will need a more powerful pump than the less viscous fluids. Other factors that need to be considered in selecting pumps are the pressure heads and volumetric flow rates of the fluids. Most pump suppliers can help you in selecting the pump you need. Some suppliers specialize in the service and sales of diaphragm and centrifugal pumps. Others supply and service pump types such as air operated double diaphragm (AODD), acid, boiler, centrifugal, circulating, condensate, drum, food, gear, hose, magnetic driven, metering, piston, plastic, scrubber, rotary, self priming, sewage, submersible, sludge, screw, slurry, solids handling, sump, turbine, water and others.
