Wilden shaft 15-3805-09

The Wilden 15-3805-09 shaft is the central rod (shaft) that connects two diaphragms and moves back and forth within the pump, enabling fluid transfer.

Material: Made of stainless steel. Some alternative designs or equivalents may include carbon steel. This material provides high strength and resistance to corrosion when in contact with the pumped medium (if parts of the shaft are immersed in liquid) and condensation in the air duct.

Weight: Approximate weight is approximately 0.98 kg (2.17 lbs).

Pump Compatibility

Size: Designed for Wilden 3-inch (76 mm) diameter pumps.

Pump Series: Used in a wide range of 3-inch models, including:

Turbo-Flo® (T15)

Construction: Used in both bolted and clamped metal pumps.

Part 15-3805-09 is often referred to as a "SOL Combo" (Solenoid Combination) shaft, indicating its configuration intended for use with certain types of pilot valves or solenoid control in an ADS system.
