There are several reasons why a displacement pump may not be able to pressurize, including: Clogged or blocked suction line: If the suction line is blocked or blocked, the pump will not be able to draw in enough fluid to build pressure. Air Leaks: If there is an air leak in the suction line or elsewhere in the system, air may be drawn in instead of fluid, which prevents the pump from pressurizing. Worn or damaged seals: The seals in a plunger pump wear over time, allowing fluid to leak and reducing the pressure that can build up. Improperly sized plunger or valve: If the plunger or valve is not the correct size for the application, it may not be able to generate enough pressure. Insufficient or inconsistent power supply: The pump may not be getting enough power to generate the necessary pressure. Clogged or damaged discharge line: If the discharge line is blocked or damaged, the pump may not be able to push fluid through and build up pressure. To effectively troubleshoot a problem, it is important to diagnose the specific cause of the problem. If you are unsure of the cause of the problem, you should consult a trained professional. Improper Valve Operation: Piston pumps use valves to control the flow of fluid, and if these valves are not working properly or adjusted properly, it may prevent the pump from pressurizing. 90-L-100-KA-1-AB-80-S-3-C7-F-03-GBA-20-20-24 90L100KA1AB80S3C7F03GBA202024 90L100-KA-1-AB-80-S-3-C7-F-05-GBA-26-26-30 90L100KA1AB80S3C7F05GBA262630 90-L-100-KA-1-AB-80-S-3-F1-E-00-GBA-32-32-24 90L100KA1AB80S3F1E00GBA323224 90-L-100-KA-1-AB-80-S-4-F1-E-00-GBA-35-35-24 90L100KA1AB80S4F1E00GBA353524 90L100-KA-1-AB-80-S-4-F1-E-00-GBA-42-42-24 90L100KA1AB80S4F1E00GBA424224 90-L-100-KA-1-AB-80-S-4-F1-E-00-GBA-42-42-24 90L100KA1AB80S4F1E00GBA424224 90-L-100-KA-1-AB-80-S-4-S1-E-00-GBA-42-42-24 90L100KA1AB80S4S1E00GBA424224 90-L-100-KA-1-AB-81-P-3-F1-F-00-GBA-35-35-24 90L100KA1AB81P3F1F00GBA353524 90-L-100-KA-1-AB-81-P-3-F1-F-03-GBA-42-42-24 90L100KA1AB81P3F1F03GBA424224 90-L-100-KA-1-AC-61-P-4-F1-E-03-GBA-35-35-24 90L100KA1AC61P4F1E03GBA353524 Improper Maintenance: Regular maintenance of your piston pump is very important to ensure its continued efficient operation. If the pump is not maintained properly, it can cause problems such as worn or damaged components that prevent the pump from pressurizing. Improper Installation: The plunger pump must be installed properly for it to operate effectively. If the pump is installed incorrectly, it can cause issues such as misalignment that prevent the pump from pressurizing. Mechanical failure: In some cases, a mechanical failure can be the reason the piston pump is unable to pressurize. This can happen if parts such as plungers or valves are cracked or damaged, preventing the pump from operating properly. Overall, there are many factors that can cause a plunger pump to fail to pressurize. It is important to perform regular maintenance and inspections to catch and fix any problems before they become more serious. Also, if you are unsure of the cause of the problem, consulting a professional can help ensure that it is effectively resolved. Incorrect Fluid Viscosity: Piston pumps are designed for a specific type of fluid, and pumping a fluid that is too thick or too thin will affect the pump's ability to pressurize. Corrosion or damage to pump components: Exposure to corrosive fluids or other environmental factors can cause corrosion or damage to pump components, preventing them from generating pressure. Worn or damaged bearings: Bearings play an important role in the operation of a plunger pump, and if they are worn or damaged, it can affect the pump's ability to generate pressure. Insufficient Lubrication: Proper lubrication is important for the smooth operation of a piston pump. If the pump is not adequately lubricated, it will cause increased friction which will prevent the pump from generating pressure. Incorrect pump speed: The speed of a displacement pump affects its ability to generate pressure. If the speed is too slow, the pump may not be able to generate enough pressure to meet the needs of the system. Fixing these problems may involve adjusting pump settings or replacing damaged components. It is important to identify the specific cause of the problem in order to determine the best course of action. In some cases, it may be necessary to consult a professional to ensure the pump is properly diagnosed and repaired. Improper pump and motor alignment: Piston pumps are usually driven by an electric motor, and improper alignment between the pump and motor can cause excessive wear and damage to the pump components, preventing it from producing pressure. 90-L-100-KA-1-BB-60-L-3-S1-E-03-GBA-35-35-24 90L100KA1BB60L3S1E03GBA353524 90-L-100-KA-1-BB-60-L-3-T2-E-03-GBA-35-35-24 90L100KA1BB60L3T2E03GBA353524 90-L-100-KA-1-BB-60-P-3-F1-E-03-GBA-23-23-24 90L100KA1BB60P3F1E03GBA232324 90-L-100-KA-1-BB-60-R-3-F1-F-03-GBA-42-42-30 90L100KA1BB60R3F1F03GBA424230 90-L-100-KA-1-BB-60-R-3-S1-E-03-GBA-42-42-26 90L100KA1BB60R3S1E03GBA424226 90-L-100-KA-1-BB-80-P-4-C7-F-03-GBA-29-29-26 90L100KA1BB80P4C7F03GBA292926 90-L-100-KA-1-BB-80-P-4-S1-E-03-GBA-20-20-24 90L100KA1BB80P4S1E03GBA202024 90-L-100-KA-1-BB-80-R-4-F1-E-03-GBA-42-14-24 90L100KA1BB80R4F1E03GBA421424 90-L-100-KA-1-BC-60-D-3-C7-L-03-GBA-20-20-28 90L100KA1BC60D3C7L03GBA202028 90-L-100-KA-1-BC-60-L-3-F1-E-03-GBA-35-35-24 90L100KA1BC60L3F1E03GBA353524 Cavitation: Cavitation occurs when the pressure in a pump drops below the vapor pressure of the fluid being pumped, causing air bubbles to form and rapidly collapse. This could damage the pump and prevent it from producing pressure. Improper priming: Piston pumps require proper priming to ensure they are full of fluid before running. It prevents the pump from generating pressure if the pump does not prime properly. Insufficient inlet pressure: Piston pumps require a certain level of inlet pressure to function properly. If the inlet pressure is too low, it will prevent the pump from producing pressure. Operating outside the pump's specified range: Piston pumps are designed to operate within a certain pressure and flow range. If the pump is run outside of this range, it may damage the pump components and prevent them from producing pressure. Determining the specific reason why your plunger pump is failing to pressurize can be a complex process that may require the assistance of a trained professional. Regular maintenance and inspections can help prevent many problems that can prevent a pump from producing pressure. Additionally, proper installation, operation and maintenance help ensure that the pump operates within its specified range and continues to operate effectively.
