In the world of high-pressure pumps, there are more varieties of high-pressure pumps available. High pressure pumps are used on a daily basis in all kinds of different industries. E.g., ro high pressure pumps (high pressure pumps for reverse osmosis) are the major energy consumers in RO plants, and at most times, selection amongst the best available pump is the only choice which can be made for an optimum working point.
It is called the centrifugal pump, and it’s used to carry liquid through a pipe way for water treatment, food, chemicals and so on. When the liquid meets the pump, it goes onto something called an impeller which slings the liquid away, which changes the liquid’s direction, therefore increasing the pressure.
It is called the container pump, and it’s special in the way that it is specially designed to move dangerous liquids in and out of areas, even highly flammable or toxic ones.
It’s very versatile and can be used for processing chemicals, perfumes, cosmetics, and even in the food industry. The drum pump is known for performing very well even in high stress applications.
Either a reciprocating type, sometimes called a plunger pump or Multi stage impeller pumps are good for high head. There are a number of considerations that will dictate the proper pump such as is the fluid viscous, is it clean, does it have stringy or solid particles suspended in it, can it withstand the temperature increase due to the work done on the fluid etc.
A type of reciprocating pump designed to move and pressurize fluid using one or more reciprocating pistons, which are normally driven by an electric motor through a crankshaft and connecting rod.
There are many types, but they all employ at least one piston moving in an enclosed cylinder. The piston normally has one or more O-rings on its periphery, to seal against the cylinder as the piston moves. The piston moves back and forth in the cylinder, alternately drawing liquid into the cylinder and then pushing it out under pressure as the volume in the cylinder gets progressively larger and then smaller as the piston reciprocates.
Flow rate ranges between 5 and 700 gpm.
Total head (pressure) ranges between 50 and 5,000 psi
Horsepower ranges between 1 and 500 hp

Like most types of positive displacement pumps, piston pumps use the force of the pumping mechanism to expand and contract an internal movable volume of liquid. The power to drive the piston is supplied by an electric motor, internal-combustion engine, or other power source - although more primitive piston pumps may be driven by hand, wind, or flowing water. The motion behind the piston is usually rotational.
Check valves on either side of the pumping chamber prevent fluid from flowing in the wrong direction. Piston pumps can have more than one piston and set of check valves. A pump with two pistons and two sets of check valves would be called a duplex pump, one with three would be called a triplex pump, with five a quintuple pump, etc.
Piston pumps can be single acting or double acting. The double acting version involves fluid on both sides of the piston, and two sets of check valves, one on each side of the piston. While the piston is in-taking on one side, it is exhausting on the other. Thus, each time the piston moves in one direction from one end to the other, a full pumping cycle (intake and discharge) has been completed. For single acting versions, the piston must move in both directions to complete a full pumping cycle.
Piston pumps are used as hydraulic pumps to power heavy machinery, and they’re also useful in smaller machines such as paint sprayers. Larger, more robust versions of this pump type are used in oil production and other industrial applications. Axial piston pumps and radial piston pumps, both of which consist of several pistons arrayed in a circular cylinder block, are useful in high-tech and advanced industrial applications.
As you can see. There are lots of pump types available, but which one is right for you? Understanding which pump type is right for your application is critical to reduce costs and increase the life of your pump and system. Contact AWS-HYDRO to explore more.
