Piston pumps and metering pumps are two different types of positive displacement pumps that are used in various industrial applications. While both types of pumps operate on the same basic principle of using a piston or plunger to move fluid through a system, there are several key differences between them. Piston pumps, also known as reciprocating pumps, use pistons or plungers to move fluid through a system. The piston, or plunger, moves back and forth within the cylinder, drawing fluid into the cylinder during the intake stroke and pushing it out during the exhaust stroke. Piston pumps are often used in applications requiring high pressure output, such as industrial cleaning or water treatment applications. In contrast, a metering pump is a pump designed to accurately dispense precise amounts of fluid into a system. Unlike plunger pumps, which are designed to provide a continuous flow of fluid, metering pumps operate in cycles, dispensing a certain amount of fluid with each stroke. Metering pumps are often used in applications that require precise fluid metering, such as chemical processing or water treatment applications. A major difference between piston pumps and metering pumps is the level of precision they offer. While both types of pumps can operate very precisely, metering pumps are specifically designed for precise metering of fluids and often incorporate specialized control mechanisms, such as variable speed drives or electronic controls, to ensure precise fluid delivery. Another difference between the two pumps is their flow capacity. Piston pumps are generally designed to provide continuous fluid flow, with a high pressure output, while metering pumps are designed to provide precise intermittent fluid flow, with a lower pressure output. In summary, piston pumps and metering pumps are two different types of positive displacement pumps used in different types of industrial applications. Piston pumps are typically used in applications requiring high pressure output, while metering pumps are used in applications requiring precise fluid metering. 90-L-075-KT-1-BB-80-R-3-C6-D-02-GBA-35-35-20 90L075KT1BB80R3C6D02GBA353520 90-L-075-KT-1-BB-80-S-3-S1-D-02-GBA-42-42-24 90L075KT1BB80S3S1D02GBA424224 90-L-075-KT-1-BC-80-R-4-S1-C-03-GBA-35-35-24 90L075KT1BC80R4S1C03GBA353524 90-L-075-KT-1-CD-60-D-3-C7-L-00-GBA-45-45-24 90L075KT1CD60D3C7L00GBA454524 90-L-075-KT-1-CD-80-R-4-S1-C-03-GBA-35-35-24 90L075KT1CD80R4S1C03GBA353524 90-L-075-KT-1-CD-80-S-3-C7-D-00-GBA-32-32-28 90L075KT1CD80S3C7D00GBA323228 90-L-075-KT-1-CD-80-S-3-C7-D-00-GBA-35-35-28 90L075KT1CD80S3C7D00GBA353528 90-L-075-KT-1-CD-80-S-3-C7-E-00-GBA-35-35-28 90L075KT1CD80S3C7E00GBA353528 90-L-075-KT-1-CD-80-S-3-S1-C-02-GBA-42-42-24 90L075KT1CD80S3S1C02GBA424224 90-L-075-KT-1-CD-80-S-3-S1-C-04-GBA-42-42-24 90L075KT1CD80S3S1C04GBA424224 Another major difference between piston pumps and metering pumps is their design. Piston pumps are usually designed with a simple reciprocating mechanism, which allows them to generate high pressures and flow rates. They are often used in heavy-duty applications, such as oil and gas drilling or industrial cleaning, where they need to withstand harsh conditions and provide reliable operation. Metering pumps, on the other hand, are designed with more complex mechanisms that allow them to dispense precise amounts of fluid. They often contain specialized components, such as check valves or flow meters, to ensure accurate metering and prevent fluid backflow. Metering pumps are commonly used in chemical processing, water treatment, and other applications where accurate metering of fluids is critical to system operation. One advantage of plunger pumps is their ability to handle a wide variety of fluids and viscosities. They are capable of pumping fluids with high solids content or high viscosity, such as slurries or oils. This makes them ideal for applications where other types of pumps may struggle to handle fluids. Metering pumps, on the other hand, are often used in applications where precise amounts of fluid need to be added to the system. This may include adding chemicals to process streams or adding water treatment chemicals to municipal water supplies. Metering pumps are often used in conjunction with flow meters or other monitoring equipment to ensure the correct amount of fluid is dispensed. In summary, piston pumps and metering pumps are two different types of positive displacement pumps used in different types of industrial applications. Piston pumps are typically used in heavy-duty applications requiring high pressure output, while metering pumps are used in applications requiring precise metering of fluids. Each type of pump has its own advantages and disadvantages, and the choice of pump will depend on the specific requirements of the application. Another important difference between plunger and metering pumps is their method of operation. Piston pumps operate by moving fluid through the system through a reciprocating motion. This motion creates a pulsating flow of fluid, which is useful in some applications, such as oil and gas drilling, where the pulsating flow helps break up solids and increase flow rates. Metering pumps, on the other hand, dispense a certain amount of fluid by using precise and consistent strokes. This makes them ideal for applications requiring precise metering of chemicals or other fluids. 90-L-075-KT-1-CD-80-S-3-S1-D-02-GBA-42-42-24 90L075KT1CD80S3S1D02GBA424224 90-L-075-KT-1-CD-80-S-4-C6-D-03-GBA-38-38-24-F026 90L075KT1CD80S4C6D03GBA383824F026 90-L-075-KT-1-NN-60-D-3-S1-L-00-GBA-45-45-24 90L075KT1NN60D3S1L00GBA454524 90-L-075-KT-1-NN-60-L-4-S1-D-03-GBA-26-14-26 90L075KT1NN60L4S1D03GBA261426 90-L-075-KT-1-NN-60-R-4-S1-D-03-EBC-38-38-24 90L075KT1NN60R4S1D03EBC383824 90-L-075-KT-1-NN-60-S-3-S1-D-03-EBC-38-38-24 90L075KT1NN60S3S1D03EBC383824 90-L-075-KT-1-NN-80-R-3-S1-D-03-GBA-35-35-24 90L075KT1NN80R3S1D03GBA353524 90-L-075-KT-1-NN-80-R-4-S1-D-03-GBA-35-35-24 90L075KT1NN80R4S1D03GBA353524 90-L-075-KT-1-NN-80-S-3-C7-D-00-GBA-35-35-28 90L075KT1NN80S3C7D00GBA353528 90-L-075-KT-1-NN-80-S-3-S1-D-00-GBA-32-32-28 90L075KT1NN80S3S1D00GBA323228 One of the advantages of plunger pumps is their ability to generate high pressures and high flow rates. They are typically used in heavy-duty applications that require the movement of large volumes of fluid quickly, such as industrial cleaning or water treatment. Piston pumps can be used to pump fluids with viscosities up to 5000 centipoise, which makes them ideal for pumping slurries or other viscous fluids. Metering pumps, on the other hand, are often used in applications that require precise metering of fluids. They can be used to dispense a wide range of chemicals and other fluids and are commonly used in water treatment, chemical processing and other industrial applications. In summary, the main differences between piston and metering pumps include their method of operation, their ability to handle different types of fluids and viscosities, and their level of precision and accuracy. Pump selection will depend on the specific requirements of the application, including the type of fluid being pumped, the flow and pressure required, and the level of precision required.
