- Graco 1040 series fluid section pumps
- Industrial AODD fluid handling units requiring reliable check valve seating
Product Description
The Graco 15B633 Ball Seat 1040 is a precision‑machined seating surface designed to pair with the check‑valve ball inside the pump’s fluid manifold. It forms a critical sealing interface that ensures proper one‑way flow of material while withstanding frequent cycling and fluctuating pressures.
Manufactured to OEM standards, this ball seat is crafted from high‑quality alloy (or stainless steel) and finished for a tight, durable seal. When installed, it helps prevent back‑flow, leaks, and violation of the pump’s design specifications, thereby ensuring consistency in operation and reducing downtime caused by fluid section failures.
Key Features & Specifications

Why It Matters
In a high‑cycle diaphragm pump, the check‑valve ball and its seat endure frequent stress and must consistently create a leak‑free seal. A worn or improperly seated 15B633 will result in back‑flow, reduced suction lift, erratic output or accelerated wear of surrounding parts. Using the correct OEM ball seat ensures proper valve operation, optimal pump efficiency and longevity of your system.
Installation & Maintenance Advice
- Always relieve pump pressure and drain fluid before disassembling the fluid section.
- Remove the manifold and inspect both the check‑valve ball and the seat; replace the seat if pitting, scoring or deformation is visible.
- Clean mating surfaces thoroughly before installation—any debris or residue can compromise the seal.
- Re‑assemble per the manufacturer’s torque specifications and cycle the pump at low pressure first to confirm proper check‑valve operation.
- As part of scheduled maintenance, replace both the seat and ball together to ensure optimal fit and function.
