Bearing
If you know a little bit about the role of bearing in the water pump – be it for Cummins engine or anything else, you can guess how crucial the bearing is for the performance of a water pump. To explain further, a bearing can help you avoid tragedies, for instance, water pump failure.
You’ll notice a leak in the water pump if the bearing starts malfunctioning. In that case, there will be a noticeable change in the sound produced by the bearing. That practically tells you that you should bring a change shortly. Therefore, you must pick a water pump that comes with a sound bearing.
Weep Holes
These days, most of the water pumps come with weep holes. They are brilliantly multi-tasking water pumps. If you like to purchase a water pump for your Cummins engine with weep holes, you have to keep some factors in consideration.
Some weep holes tend to have leaks at the bottom. If this happens to you with your water pump, you’ll experience tragedy someday. Hence, make sure the weep holes are free from any leak at the bottom.
Bearing Seal
Bearing seal is another crucial factor to be highly serious when you invest money for the water pump. It holds a significant share of importance. The water pump is likely to be exposed to contamination by the course of use. The bearing seal makes sense when your water pump needs to keep safe from any sort of contamination.
Impeller Blades
Impellers blades are pretty fragile which tend to break down in heavy pressure if not durable enough. It is more of a newly-experienced issue that is seen in the case of plastic-made impeller blades.
If the blades break, you’ll notice a vibration sourcing from the pump housing. Consequently, the broken blade can lead the engine to fail by overheating the engine. So, consider the quality of the blades during purchasing.
