Astral Hurlcon Pumps Mechanical Seal 75508 / 75509 / PS3868

Astral Hurlcon Mechanical Seal – Extra Heavy Duty (PS3868 / 75508 / 75509)

Replace the mechanical seal on your Astral Hurlcon pool pump with this genuine Astral Pool extra heavy duty mechanical seal. The mechanical seal prevents water from leaking along the pump shaft between the wet end and the motor. A worn or failed mechanical seal causes water to drip from the pump body, which can damage the motor bearings and lead to motor failure if left unaddressed.

Frequently Asked Questions

How do I know if my mechanical seal needs replacing?

The most common sign of a failed mechanical seal is water dripping from the pump body near the motor end, or a wet patch forming under the pump during operation. You may also notice the pump losing prime more frequently. Replace the seal promptly — water ingress can damage motor bearings and lead to motor failure.

Can I replace just the mechanical seal, or do I need to replace the whole pump?

In most cases the mechanical seal can be replaced without replacing the entire pump. The pump wet end needs to be disassembled to access the seal. If you are not comfortable with this repair, contact a pool technician.

Is this a genuine Astral Pool part?

Yes — PS3868 (also referenced as 75508 and 75509) is a genuine OEM Astral Pool replacement mechanical seal, not an aftermarket substitute. Genuine parts ensure correct sizing and reliable sealing.

Does this suit the Viron XT pump?

This seal suits the Viron XT P320 and P520 produced between November 2020 and June 2021, and the Viron XT MKII P320C and P520C. If your Viron XT was produced outside this date range, check your pump’s parts diagram or contact us to confirm compatibility before ordering.
