ARO 92926 Polypropylene Valve Seat for 1 in. Metallic AODD Pumps

ARO 92926 Polypropylene Valve Seat

The ARO 92926 is a replacement polypropylene valve seat designed for compatible ARO 1-inch metallic air-operated double-diaphragm pumps. It forms part of the fluid-section check-valve system and provides the sealing surface used by the pump check ball during operation.

Polypropylene Construction

The 92926 is manufactured from polypropylene. This material is commonly used in ARO fluid-section components for compatible industrial liquid-transfer applications.

Always verify polypropylene compatibility with the actual process fluid, chemical concentration and operating temperature before installation.

Designed for 1 Inch Metallic Pumps

ARO replacement-parts references identify the 92926 specifically as a polypropylene seat for 1-inch metallic pumps.

Published pump parts listings show it in compatible 666100 and 666120 metallic Pro-Series configurations. :chatgpt-content-reference{index="1"}

Item 21 in the Fluid Section

Applicable ARO parts listings identify 92926 as Item 21 in the fluid section.

This reference helps technicians locate the correct valve seat during pump disassembly and rebuild work.

Four Seats in the Documented Assembly

Applicable ARO pump parts tables specify four 92926 valve seats per documented assembly. :chatgpt-content-reference{index="2"}

This quantity refers to the number installed in the pump and should not automatically be interpreted as the supplier sales-package quantity.

Check-Ball Sealing Function

The valve seat works together with the pump check ball to control directional fluid movement through the inlet and discharge passages.

Wear, grooves, deformation, chemical attack or debris on the seating surface can reduce sealing effectiveness and may contribute to reduced flow, poor priming or inconsistent pumping performance.

Compatible Model Examples

Published parts references include compatible models such as:

• 666100-322-C
• 666100-344-C
• 666120-311-C
• 666120-322-C
• 666120-3EB-C

This is a representative list rather than a complete compatibility list. Verify the full ARO pump model before ordering. :chatgpt-content-reference{index="3"}

Included in Some Fluid Section Service Kits

ARO-compatible parts listings indicate that the 92926 may be included in fluid-section service-kit configurations that include seats.

If multiple fluid-section components require replacement, compare the applicable service kit with purchasing individual seats separately.

Ordering ARO 92926

Before purchasing, confirm:

• ARO part number 92926
• Complete pump model
• 1-inch metallic pump configuration
• Polypropylene seat requirement
• Item 21 position
• Required replacement quantity

Using the exact manufacturer part number helps ensure the correct valve-seat material is selected for the pump fluid section.
