Hose Pumps-Hose pumps, or peristaltic pumps, are a type of positive displacement pump that use a roller to move fluid through a tube or hose. Hydraulic Pumps-a type of PD pump used to pressurize hydraulic fluid. The fluid is then used to do work by operating pistons in a hydraulic system. There are many different types, including: piston, gear, screw, plunger, and vane pumps. In-line Pumps-configured with the suction and discharge connections are in line. They use a diaphragm on each side of the pumping chamber. End Suction Pumps-a type of centrifugal pump that has a casing with the suction coming in one end and discharging out the top. Explosion Proof Pumps-built to prevent the pump from becoming ignited and exploding. Bellows Pumps-use a bellows device to pump fluid through a piping system. A bellows is a compressible container with an outlet nozzle. Bellows pumps are considered a positive displacement pump type. Booster Pumps-used to increase the pressure of liquid that is already flowing in a system. They use a diaphragm on each side of the pumping chamber. End Suction Pumps-a type of centrifugal pump that has a casing with the suction coming in one end and discharging out the top. Explosion Proof Pumps-built to prevent the pump from becoming ignited and exploding. A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps can be classified into three major groups according to the method they use to move the fluid: direct lift, displacement, and gravity pumps. Some positive displacement pumps use an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. noun. The definition of a pump is a device that forces gas or liquid into something, or pulls gas or liquid out of something. 1  An example of a pump is what you would use to fill an air mattress. 2  An example ofa pump is the machine used to milk a cow.  An external infusion pump is a medical device used to deliver fluids into a patient’s body in a controlled manner. There are many different types of infusion pumps, which are used for a variety of purposes and in a variety of environments. A number of commonly used infusion pumps are designed for specialized purposes. These include: 1  Enteral pump-A pump used to deliver liquid nutrients and medications to a patient’s digestive tract. There are two general types of water pumps: centrifugal pumps and positive displacement design type. Both types follow the same purpose, which is to move water from one point to another continuously. These two major components have a wide variety of options that might be used depending on your project specific needs. Water pumps. There are many types of water pumps, but there is no ideal pump for every occasion. Water pumps are used mainly for dewatering purpose to reduce downtime from large rain events. Water pumps should be evaluated based on performance, low downtime, durability and price. Refer to the table below for information about the types of well pumps available. Utility pumps are a broad classification of pumps available in a variety of configurations and used for short-term or emergency use to move liquids, often water, from one place to another. Refer to the table below for the most common utility pump types and functions they provide.  There are three types of centrifugal pumps—radial, mixed, and axial flow pumps. In the radial pumps, pressure is developed completely through a centrifugal force, while in axial pumps pressure is developed by lift generated by the impeller. Mixed flow pumps develop flow through a centrifugal force and the impeller. 37 While pumps typically operate to serve various chemical process support equipments such as chillers, cooling towers, material transfer, etc., pumping is considered an individual process separate from the processes of the aforementioned equipment. A pump is a device used to raise, compress, or transfer fluids. Radial centrifugal pumps are centrifugal pumps that completely use centrifugal force to develop pressure. Mixed centrifugal pumps are centrifugal pumps that use both centrifugal force and the action of the impeller on the liquid to develop pressure. Centrifugal pumps can use many sources for a power supply, including AC power, DC power, natural gas, steam, water, gasoline, and solar power. Some centrifugal pumps, when purchased, do not include a power source. More about Centrifugal Pumps. Click here to find Centrifugal Pumps Manufacturers. There are three general categories that centrifugal pumps fall into: mixed flow, axial flow, and radial flow. Axial flow centrifugal pumps are centrifugal pumps that use the direct action of the impeller on the liquid to develop pressure. Centrifugal pumps can use many sources for a power supply, including AC power, DC power, natural gas, steam, water, gasoline, and solar power. Some centrifugal pumps, when purchased, do not include a power source.
