Wilden 04-3529-52 center block gasket

The Wilden 04-3529-52 Center Block Gasket is a specialized center block gasket used in Wilden air-operated pumps.

Key Features:

Purpose: Provides a tight seal between the center block and the air valve (ADS), preventing compressed air leaks.

Material: Buna-N (NBR, nitrile rubber). This material is oil-resistant and maintains its elasticity under normal operating conditions.

Weight: Approximately 0.11 kg (0.25 lbs).

Compatibility:

Pump Series: Specifically designed for Pro-Flo® V systems (models PV4 and PV15) and some classic P4 and P15 models.

Sizes: Fits pumps with 1.5" (38 mm) and 3" (76 mm) port diameters.

Construction: For use in metal pumps (aluminum, stainless steel, cast iron).

Important information:

In current Wilden parts catalogs, part number 04-3529-52 is often replaced by its modern equivalent, 04-3529-56 (made of the same material but with an updated configuration for increased durability). During maintenance, it is recommended to inspect the gasket for cracks and deformations, as any loss of seal in this component will result in reduced pump performance.
