Hose pumps use a sequential constriction of a length of hose to move fluids through positive displacement. There are two types: rotary and linear. Tube pumps are effective for pumping sterile or hazardous fluids and are commonly used in the chemical, medical, and cleaning industries. They are ideal for pumping fluids with varying viscosities and […]
Dosing pumps precisely control liquid flow rates by dispensing exact amounts of liquid per revolution or stroke. They are used in medicine, manufacturing, and commerce. There are two types of dosing pumps: variable displacement constant speed and fixed displacement variable speed. Peristaltic dosing pumps are also widely used in medicine and laboratory work. A dosing […]
A double breast pump can save time and prevent milk wastage by drawing milk from both breasts at the same time. There are different types, with plug-in models being the most reliable. It’s important to check if a model can be converted to a double pump. The double pump is more efficient, but frequent use […]
Air source heat pumps use outside air to heat buildings, reducing costs and carbon footprint. They require little maintenance and have minimal running costs. They are less efficient than ground source pumps but more efficient than gas, oil or electric heating. They can be installed in existing buildings, but installation during construction is more cost-effective. […]
Pumpjets are a propulsion system for boats that draw water into the propulsion assembly and force it out through a nozzle. They are safer, more maneuverable, and operate in shallow waters, but are more expensive and require more maintenance. They are used in both small and large vessels, including submarines. A pumpjet is a propulsion […]
Diaphragm pumps use a flexible diaphragm and check valves to move fluids in a two-part cycle. They can be powered by air, fluid, or motors and can run dry without damage. There are two types of actuators: compressed air/fluid and mechanical. A diaphragm pump is a positive displacement pump that uses a flexible diaphragm to […]
Mechanical fuel pumps deliver fuel to carbureted engines and are found on older vehicles. They are mounted on the side of the engine, run on engine momentum, and provide a constant supply of fuel to the carburetor. They are easy to replace, but can’t handle high pressure fuel systems and have been replaced by electronic […]
A circulation pump moves liquid through a piping system, commonly used in heating and cooling systems. It has a housing, impeller, motor, and support bearings. It can also be used for mixing liquids and powders. Materials used vary based on the solution and operating conditions. Many fluid systems require frequent or continuous flow of liquid. […]
Circulation pumps move liquids through piping systems and are used in heating, cooling, and mixing applications. They consist of a housing, impeller, motor, and support bearings. They can be electrically powered and made of various materials depending on the solution and operating conditions. Many fluid systems require frequent or continuous flow of liquid. A circulation […]
An airlift pump uses air to pump fluid without mechanical contact. It is useful in situations where the liquid is caustic or mixed with an abrasive. Buoyancy and fluid pressure enable its operation. Common uses include water wells and dredging operations. An airlift pump is a piece of equipment that has no mechanical contact with […]
A water pump bearing supports the impeller shaft and seals coolant inside the pump housing. Signs of damage include squealing sounds and coolant leaks. The bearing is typically a sealed, machined race designed to withstand harsh operating conditions. Most water pumps cannot be rebuilt due to the extreme conditions they operate under. A water pump […]
Pump pulleys use fluid to pump and transmit power, commonly found in automotive and industrial machinery. Compact and lightweight pulleys improve efficiency and economic quality. They are used in car water pumps, power steering systems, and power take-offs for tractors and semi-trailers. A pump pulley is any type of pulley that uses a fluid, such […]
Pump boats, a type of outrigger canoe with side support floats, are popular in Hawaii for racing and in the Philippines for transportation. They can be powered by gasoline or diesel engines or oars. They were originally used for migration and fishing and are now made of modern materials like Kevlar. Modern racing boats have […]
Pump testing evaluates pump efficiency, safety, and functionality. Fluid pressure and flow are commonly evaluated, and tests can be done on individual pumps or entire stations. Flowmeters are used for testing, and guidelines ensure consistent results. Thermodynamic tests focus on energy use and temperature changes. Pump testing is a method by which a wide variety […]
A hydraulic air pump uses air pressure to pump hydraulic fluid to various equipment, and includes a relief valve to regulate pressure and prevent damage. It is more productive than manual pumps and reduces operator fatigue. Choosing the correct pump involves determining the desired air pressure and portability, and ensuring features to manage air return […]
Electric hydraulic pumps compress fluid to drive a secondary mechanism, typically using gear or lobe pumping mechanisms. They can be driven by AC or DC motors and are commonly used in industrial and mobile applications. Hydraulic pumps draw fluid from a reservoir and deliver it under high pressure to operate positive displacement mechanisms. Electric water […]
Electric hydraulic pumps compress fluid to drive a secondary mechanism, typically using internal gear or lobe mechanisms and operated at low speeds. They can be driven by AC or DC motors and come in various sizes. Hydraulic pumps draw fluid from a reservoir and deliver it under high pressure to operate positive displacement mechanisms. Electric […]
Electromagnetic pumps use magnetic fields to create flow in magnetically charged materials such as liquid metal, and are useful for cooling nuclear reactors and handling difficult materials. They have advantages over mechanical pumps and can be configured for specific applications. Different types of electromagnetic pumps exist, including direct current conduction, alternating current conduction, and linear […]
Diesel engines rely on a small component called a diesel pump to carry fuel from the tank to the engine for combustion. There are two types of pumps: mechanical and fuel injection.
