Xylem 2535320 Marlow Pump Mechanical Seal

Product Description

The XYLEM 2535320 is a mechanical seal designed for Marlow-brand pumps. Mechanical seals prevent fluid from leaking along the rotating shaft where it exits the pump housing. This seal serves as a wear component in pump assemblies used across plumbing, HVAC hydronic systems, pool circulation, and light industrial fluid-handling applications. Installation is typically performed by licensed plumbers, HVAC technicians, or pump service technicians during routine maintenance or pump rebuild service.

The 2535320 is used as a replacement mechanical seal in Marlow pump assemblies. Marlow pumps appear in residential and light commercial settings, including pool and spa circulation systems, hydronic heating loops, and general water transfer applications. This seal is sold individually and is intended as a direct service replacement part.

Key Features

• OEM-style replacement mechanical seal for Marlow pump assemblies
• Prevents shaft leakage at the pump housing exit point

Compatibility

Designed as an OEM-style replacement mechanical seal for Marlow-brand pump assemblies. Consult Marlow documentation or cross-reference the pump model number to confirm fitment before installation.

Installation Notes

Mechanical seal replacement is typically performed by a licensed plumber or qualified pump technician. Always shut off power to the pump motor and close all isolation valves before disassembling the pump housing. Handle the seal faces carefully to avoid scratching the lapped mating surfaces, as surface damage will cause immediate leakage. Follow the pump manufacturer's service documentation for proper seal seating depth and impeller clearance.
