help Chesterton 1510/1510L FAQ
What type of pump seal is the Chesterton 1510?
The 1510 is a mechanical seal system used around a rotating pump shaft to control leakage between the process fluid and atmosphere. It is an engineered sealing product from A.W. Chesterton, not packing that is simply compressed into a stuffing box.
What is the difference between the Chesterton 1510 and 1510L?
The 1510L is a related configuration intended for applications requiring its alternative dimensional arrangement. Because pump shafts, chambers, and installation lengths vary, the two designations should not be treated as interchangeable without checking Chesterton's dimensional drawing.
What information is needed before ordering a 1510 or 1510L seal?
A supplier will need the pump model, shaft or sleeve diameter, seal-chamber dimensions, operating pressure, temperature, speed, and process fluid. Material selection also depends on whether the service attacks common elastomers, metals, or seal faces.
Why might a newly installed 1510 seal still leak?
Possible causes include damaged faces, incorrect setting, shaft runout, dry running, poor flush conditions, or an elastomer incompatible with the liquid. A mechanical seal cannot compensate for a badly worn bearing or a pump operating far outside its intended condition.
