What are the maintenance requirements for Sumitomo gear pumps?

The maintenance requirements for the Sumitomo gear pumps are pretty simple, and you will be guided throughout the article. You should do regular checks on the seals and gaskets to avoid any leakage when they get worn out, while constant greasing of the inside parts makes it easy for them to slide against each other, thus reducing friction and wearing. Moreover, monitoring fluid levels and checking hydraulic fluid’s condition remains indispensable since low or contaminated levels can lead to poor performance. Cleaning filters and strainers regularly is also advisable to keep them at their best. Finally, a periodic general examination by skilled employees is essential because this may prevent any anticipated problems from leading to considerable downtime.
Routine checks and care
To ascertain their smooth functioning, several critical practices should be followed when undertaking routine Sumitomo gear pump checks and maintenance. First, it is important to do frequent visual checks to search for any hint of leaks or wear on gaskets and seals. Regularly lubricate the system; whether the oil levels are correct or the lubricant is in good condition may prevent rub-induced damage. Besides, monitoring pump temperature during operation is advisable since high temperatures can be a pointer to other problems. Blocking filters and screens periodically will prevent blockages and maintain optimal flow rates. Lastly, keeping service records helps monitor performance over time, thus facilitating the detection of trends that could indicate the need for repairs or replacements.
Common issues and troubleshooting
Several typical problems may arise while using Sumitomo gear pumps, each with its troubleshooting instructions. One of the prevailing problems is abnormal sound when the pump is operating, suggesting a lack of lubrication and incorrect alignment. While testing this, the systems for the oiling should be working well, and the pump should be checked to ensure it was correctly installed. Overheating is also a common problem resulting from excessive loads on the system, poor cooling mechanisms, and dirty hydraulic fluid. Their operational temperatures and the quality of oils used should be monitored to reduce this impact. Finally, leakage through gaskets or seals around pumps often implies wearing out or breakage; thus, substituting these worn-out parts will prevent further worsening and prolonged usage of gear pumps. Regular maintenance checks can be carried out to ensure that such issues are minimized, increasing the life span of gear pumps.
