Shaft seals for pumps

All pumps have a shaft, and all shafts need to sealed. Through most of the 1900 - 1999 the most common method was with braided packing. Most pumps were cheaper if you bought them with packing rather than a mechanical pump shaft seal. Today things have changed. The cost of seals has come down (since 95% of them are made off shore) and the concerns of allowing a pump to leak water (6 drops per minute with most packing) has increased. The result is mechanical pump seals are more common than ever. So, most customers prefer a mechanical shaft seal. When replacing your shaft seal, you want a seal that is as good (easy for us) or better than the original pump equipment. Our objective is to be sure the pump seal you get from us lasts longer and fits precisly. OEM's will generally supply carbon Vs. ceramic faces, but if you have an abrasive, fast, chemical, Food Grade, or hot application stock seals will likely not last long. The seal may be more expensive but your overall cost will be dramatically less. Fewer man hours, material costs (multiple seals) and lost production always makes investing in quality shaft seals a good bet. For extra durable shaft seals, ask about our USA made seals CNC machined from bar stock.
