Danfoss Series 90 piston pumps have a variety of displacement options ranging from 18 to 141cc/rev (cubic centimeters per revolution). Below are the displacement options for the different models of the Danfoss Series 90: 90R018: 18 cubic centimeters/rev 90R030: 30 cubic centimeters/rev 90R042: 42 cubic centimeters/rev 90R055: 55 cubic centimeters/rev 90R075: 75 cubic centimeters/rev 90R100: 100 cubic centimeters/rev 90R130: 130 cubic centimeters/rev 90R141: 141 cubic centimeters/rev The displacement of a plunger pump is the volume of fluid displaced by the pump's piston or plunger during one complete revolution of the drive shaft. Displacement, usually expressed in cubic centimeters per revolution, determines the flow and output pressure of the pump. It is important to select the proper displacement for a particular application, taking into account factors such as required flow and operating pressure. Using a pump that is too high or too low displacement can cause the hydraulic system to operate inefficiently or ineffectively. To select the proper displacement for your Danfoss Series 90 piston pump, it is important to consider the specific requirements of your hydraulic system. The displacement of the pump should match the flow and pressure requirements of the system as well as the size and type of other components in the system. If the pump displacement is too low for the system's requirements, it may not deliver enough flow to meet the system's requirements, resulting in poor performance or failure. On the other hand, if the displacement is too large, it may cause excessive flow and pressure, which can also cause problems such as wear or damage to components. When selecting a Danfoss Series 90 piston pump, other factors such as the pump's operating speed, efficiency and durability must also be considered. Pumps should be compatible with the fluids used in the system and should be able to perform reliably under the expected conditions. 90L075-KA-5-CD-60-P-3-C6-D-03-GBA-35-35-24 90L075KA5CD60P3C6D03GBA353524 90-L-075-KA-5-CD-60-P-3-C6-D-03-GBA-35-35-24 90L075KA5CD60P3C6D03GBA353524 90L075-KA-5-CD-60-P-3-C6-D-04-GBA-35-35-20 90L075KA5CD60P3C6D04GBA353520 90-L-075-KA-5-CD-60-P-3-C6-D-04-GBA-35-35-20 90L075KA5CD60P3C6D04GBA353520 90L075-KA-5-CD-60-P-3-C6-D-04-GBA-42-42-20 90L075KA5CD60P3C6D04GBA424220 90-L-075-KA-5-CD-60-P-3-C6-D-04-GBA-42-42-20 90L075KA5CD60P3C6D04GBA424220 90L075-KA-5-CD-60-P-3-C7-E-03-GBA-42-42-24 90L075KA5CD60P3C7E03GBA424224 90-L-075-KA-5-CD-60-P-3-C7-E-03-GBA-42-42-24 90L075KA5CD60P3C7E03GBA424224 90-L-075-KA-5-CD-60-S-3-C6-D-03-GBA-35-35-24 90L075KA5CD60S3C6D03GBA353524 90-L-075-KA-5-CD-60-S-3-C7-D-00-GBA-42-42-20 90L075KA5CD60S3C7D00GBA424220 Danfoss offers a range of additional options and features for the Series 90 piston pumps, including different shaft types, mounting configurations and control options. By careful selection of the proper pump and configuration for a specific application, optimum performance and service life of your hydraulic system can be ensured. In addition to selecting the proper displacement for your Danfoss Series 90 piston pump, it is also important to properly maintain the pump to ensure optimum performance and longevity. Regular maintenance helps prevent problems such as contamination, wear and damage, which can all affect pump performance and efficiency. Danfoss recommends the following maintenance measures for its 90 series piston pumps: Check oil level and condition regularly and change oil as needed. Use the recommended oil type and viscosity and maintain proper oil levels to ensure proper lubrication and cooling of the pump. Check the pump for leaks, damage or wear and replace any damaged or worn parts as necessary. Pay special attention to seals, bearings and other parts subject to wear. Clean the pump regularly to prevent contamination and debris buildup. Use a suitable cleaning solution and follow recommended cleaning procedures to avoid damage to the pump. Make sure the pump is properly installed and aligned and that all connections are tight. Use recommended mounting hardware and torque specifications to prevent vibration and misalignment. Check the pump control system and components and replace any damaged or worn parts as necessary. Proper control of the pump is critical for optimum performance and efficiency. By following these maintenance practices and performing regular inspections, you can extend the life of your Danfoss Series 90 piston pump and ensure optimum performance of your entire hydraulic system. 90L075-KA-5-CD-60-S-3-C7-D-03-GBA-26-26-24 90L075KA5CD60S3C7D03GBA262624 90-L-075-KA-5-CD-60-S-3-C7-D-03-GBA-26-26-24 90L075KA5CD60S3C7D03GBA262624 90L075-KA-5-CD-60-S-3-C7-D-03-GBA-42-42-24 90L075KA5CD60S3C7D03GBA424224 90-L-075-KA-5-CD-60-S-3-C7-D-03-GBA-42-42-24 90L075KA5CD60S3C7D03GBA424224 90L075-KA-5-CD-60-S-3-S1-D-03-GBA-42-42-20 90L075KA5CD60S3S1D03GBA424220 90-L-075-KA-5-CD-60-S-3-S1-D-03-GBA-42-42-20 90L075KA5CD60S3S1D03GBA424220 90L075-KA-5-CD-60-S-3-S1-D-03-GBA-42-42-24 90L075KA5CD60S3S1D03GBA424224 90-L-075-KA-5-CD-60-S-3-S1-D-03-GBA-42-42-24 90L075KA5CD60S3S1D03GBA424224 90L075-KA-5-CD-60-S-4-C7-D-03-GBA-30-30-24 90L075KA5CD60S4C7D03GBA303024 90-L-075-KA-5-CD-60-S-4-C7-D-03-GBA-30-30-24 90L075KA5CD60S4C7D03GBA303024 Another important aspect to consider when using Danfoss Series 90 piston pumps is the operating temperature range. Running the pump outside of the recommended temperature range will affect its performance and may cause damage over time. Danfoss provides temperature guidelines for its pumps to ensure optimum performance and lifetime. For example, Danfoss Series 90 piston pumps have a recommended operating temperature range of -40°C to +80°C (-40°F to +176°F). Running the pump outside of this range can lead to problems such as increased wear, reduced efficiency and even pump damage. It is also important to ensure that the hydraulic fluid used in the system is suitable for the operating temperature range of the pump. Using fluids that are not designed for the intended temperature range can cause issues such as changes in viscosity, which can affect pump performance and efficiency. In addition to the operating temperature range, other environmental factors that may affect pump performance, such as humidity, dust and vibration, must also be considered. Proper protection and maintenance of pumps and hydraulic systems can help prevent problems caused by these factors. Optimum performance and service life of Danfoss Series 90 piston pumps can be ensured by following the manufacturer's guidelines and performing regular maintenance and inspections.
