The suction cup pump, also known as pumpjack, nodding donkey, or horsehead pump, is a common oil exploration pump in Texas and other areas. It pumps oil from depths of 10,000 feet or more using a mechanical chain reaction. The pump design resembles a large pendulum and can pump 7 to 20 barrels of oil […]
A 12-volt water pump is ideal for RVs and small boats, powered by a car battery and able to pump fresh water from holding tanks or bilges. They are rugged and can withstand constant use, with plastic impellers that resist rust and corrosion. A 12-volt water pump is the ideal way to supply running water […]
Wind pumps are used to pump water from various sources for drinking, irrigation, and livestock. They can also relieve flooded areas and produce salt. There are two types: horizontal and vertical axis, with different rotor types. Piston pumps are commonly used to pump water from wells. Wind direction is important for horizontal axis wind pumps, […]
A boiler feedwater pump is used to replenish water lost during normal operation in a closed water heating vessel known as a boiler. The pump is typically driven by an electric or steam engine and preheats water before pumping it into the boiler. The system is controlled by sensors in the boiler and includes manual […]
Otto von Guericke demonstrated the power of voids in 1663 by joining two copper hemispheres and creating a vacuum. Vacuum pumps were originally used for scientific study, but evolved into practical uses like manufacturing and vehicle amenities. There are two common types: compressed air and electromechanical. They are used in semiconductor processing, brake boosters, cruise […]
Otto von Guericke demonstrated the power of a vacuum in 1663 by using horses to try and separate two copper hemispheres. Vacuum pumps were originally used by chemists to study gases and electricity, but have since evolved to play a practical role in manufacturing. There are two types of vacuum pumps: compressed air and electromechanical. […]
Pumps are mechanical devices used to move liquids or air. Pump speed determines the flow of liquid or air and varies between industries. Fuel pump flow rate is critical for engine operation, while water pump speed is used for metering. Heat pump speed measures the flow of air and is used for billing purposes. A […]
Foot pumps are simple suction pumps operated by foot pedals, used mainly for irrigation purposes in Asia and Africa. They are affordable and can be made of locally available materials. Foot pumps increase agricultural productivity, but are limited to shallow underground reservoirs and may deplete groundwater supplies over time. The foot pump is a simple […]
An axial piston pump uses a swashplate to move multiple pistons up and down, and can be used as a pump or part of other assemblies. The swashplate rotates to force the pistons to move in and out of the cylinder block. All parts must be precisely measured for proper function, and the pumps can […]
A simplex pump is a reciprocating device that pumps fluid up and down through ports at both ends of the cylinder. It is efficient and can be powered by electric, petrol, diesel or compressed air motors. Simplex pumps come in different sizes and are used in various applications, including supplying fuel oil to engines, bilge […]
A peristaltic pump is a type of pump that uses pressure and displacement to pump liquids through a hose without direct contact with the fluid. It works by allowing fluids to enter a tube and then compressing the tube with a rotor to push the liquid through the pump. It is commonly used in medical […]
The vane pump uses positive displacement with a rotor and vanes to force liquid through pipes. It creates small chambers within the larger cavity to move liquid and maintain uniform flow. It’s used in automobiles, food service, and processing of liquids or gases. The vane pump is a device that works on the principle of […]
A sand pump is a centrifugal pump used to move solid matter, particularly sand, through a piping system. It works through a grooved disc that creates a force of motion. Sand pumps are used in systems that move materials long distances and can relieve the workload of the initial pump. While there are benefits to […]
Gas pumps consist of a computer component and mechanical part that efficiently fill tanks with fuel. They are connected to a large tank underground and use a submersible or suction pump to transfer fuel to a waiting vehicle. The computer system measures the amount of fuel pumped and is linked to a computer managed by […]
Submersible pumps can operate underwater and are used for various purposes, including sump and sewage pumps. They work by protecting their motors from pumped liquid, but may corrode and be difficult to repair. However, they are self-priming and require less work than standard pumps. When choosing a submersible pump for home use, consider the specific […]
Hand pumps use human energy to operate and are commonly used for pumping water and air. Hand air pumps draw air in and force it through a nozzle while hand water pumps use suction to draw water from underground wells. They are cost-effective and can be used as a backup or primary source of water […]
Refrigeration vacuum pumps remove moisture and air from AC/R systems by creating a deep vacuum, boiling water and expelling steam and air. They are typically rotary with two-stage operation and can produce values of 50 microns or less. It is important to use the correct size pump and maintain oil levels. A refrigeration vacuum pump […]
A pump hoist is a device mounted on a truck used to replace submersible pumps and well pipes. It consists of a tower with a pulley, a hoist, and a cable. The hoist lifts the pump out of the well casing for maintenance, and the pump is reconnected after repairs. The size of the hoist […]
Impeller pumps are commonly used to move liquids with impurities through piping systems. The pump consists of a housing, impeller mechanism, motor, and support bearings. The impeller rotates and pushes the liquid outward, increasing pressure. The number of blades on the impeller can vary, and pumps can be purchased in a variety of diameters and […]
A pump jack is used to extract oil from wells with low production levels. It consists of a long beam moved by an external power source, and can run on generators or central power supplies. Production can be adjusted in response to changes in oil prices and other factors. Once extracted, the oil is moved […]
