Diffusion pumps use high-velocity steam to transport gases, creating high vacuum values. They have no moving parts, are easy to maintain, and use silicone oil or mercury as vapor materials. A diffusion pump is a device designed to pump gases with a high-velocity jet of steam as a means of transport. This process occurs as […]
A star pump, also known as a gerotor pump, is used to transport lubricating liquids and works by producing a pumping action through rotating gears. They can be made from various materials and designed for different purposes. Most consist of two interlocking gears that create a cavity for liquid to be drawn in and expelled. […]
Air lift pumps use compressed air to pump water without mechanical parts, making them suitable for pumping sensitive fluids or in sandy wells. They work by introducing air into a vertical pipe immersed in water, creating a vacuum that draws water up. They are not suitable for high-pressure applications and should be covered with a […]
Barrel pumps are used to extract liquid products from 55-gallon barrels, commonly in chemical, oil, and food industries. They can be manually, electrically, or pneumatically operated and are designed for smaller containers. Metered pumps are also available for dosing systems. Most often, a 55 gallon (45.8 liter) barrel is used to transport and store liquid […]
A charge pump is a DC-DC converter that uses capacitors to change the input voltage of a power source, making it a good option for portable electronic devices. It works by charging a capacitor to the same voltage as the power supply and placing it in series with the power supply to double the voltage. […]
A pump coupler connects the output shaft of a motor to the input shaft of a pump. Flexible couplers allow for misalignment and play, reducing wear. Flange, bellows, and gear types are common. Rigid couplers are simple, while flexible ones have an element of flexibility to accommodate misalignment and play. A pump coupler is a […]
Lobe pumps use two rotors with three lobes each to create sealed pockets that transport material from inlet to outlet. They are gentle and can pump solids, suspensions, and certain fluids. A lobe pump is a positive displacement pump that has a pair of lobe rotors that rotate within a tight fitting, sealed casing. Rotors […]
A mud pump circulates drilling fluid in a borehole using pistons or plungers. The fluid, consisting of water, petroleum, clay, and chemicals, cleans the hole, cools equipment, and prevents blowouts. Modern mud pumps have three cylinders, while older ones have two. The pump is crucial in the oil drilling process, moving rock cuttings down the […]
Screw pumps are mechanical devices used to move substances. The Archimedean screw is a basic type, while more complex variations include those with multiple screws and those used in submarines. Screw vacuum pumps use the physics of a screw pump to create a vacuum, and augers can be constructed as a variation to dig holes […]
An oil pump lubricates machine parts to reduce friction and extend their lifespan. It is commonly found in car engines and needs regular maintenance, including oil changes and level checks. Oil viscosity is important and marked on bottles with a number. An oil pump is used to supply oil to the moving parts of a […]
Fire pumps deliver water at high pressure to extinguish fires and are used in building sprinkler systems and firefighting vehicles. They were invented in the 16th century and are essential for effective firefighting. Specialized fire pumps are used for different situations, such as fire boats and foam application. A fire pump is a specialized water […]
A progressing cavity pump uses a rotor to move fluid through small chambers, allowing for consistent flow and pressure control. It is used in various applications, including oil drilling, sewage systems, and chemical manufacturing. The design minimizes wear and provides precise control. It was first developed in the 1930s and has various names. Sometimes referred […]
A volute is a part of a centrifugal pump that reduces the speed of water by increasing its pressure, balancing the pressure on the pump shaft and reducing wear. The volute chamber widens as water moves away from the impeller, decreasing velocity while maintaining increased pressure. This process transfers kinetic energy into stable pressure. Centrifugal […]
Choose a concrete pump truck with the right capacity and pumping speed for your needs. Consider tire size, ease of use, boom length, and power. Some models can also lift mud. The best concrete pump truck will carry the amount of concrete you need and be able to access the areas where you want to […]
The progressing cavity pump is a positive displacement pump that uses a helix-shaped rotor to pull fluids of varying viscosities into isolated cavities and discharge them. It is useful for wastewater management and other environments with suspended sediment. Flow rate is adjustable, and maintenance is required. Manufacturers offer a range of sizes and speeds, and […]
