Deskripsi
Sandpiper HDB2/HDB50 2" Heavy Duty Ball Valve AODD Pump Check Balls for Metallic Pumps
Genuine Sandpiper check ball replacement parts for compatible HDB2/HDB50 2" Metallic Heavy Duty Ball Valve AODD pumps. “Metallic” identifies the compatible pump construction; the check-ball material or type is selected separately from the manufacturer-listed options below.
The Sandpiper HDB2/HDB50 check ball is a wet-end check-valve component used in compatible Heavy Duty Ball Valve AODD pumps. As the diaphragms cycle, the check balls move against their valve seats to help control one-way fluid movement through the pump. Select the replacement by exact pump model, check-ball material or type and Sandpiper manufacturer part number.
Product Overview
The Sandpiper HDB2/HDB50 check ball is intended for servicing compatible 2" Metallic Heavy Duty Ball Valve AODD pumps.
The ball and valve seat work together as a one-way wet-end check valve. During each pump stroke, the ball lifts away from or returns to the seat according to the pressure difference across the fluid chamber.
Manufacturer-listed check-ball selections for this model include Santoprene, Weighted Buna, Weighted EPDM, Weighted Neoprene, PTFE. Select from the exact pump configuration and manufacturer part number, not from nominal pump size or wetted pump material alone.

How to Select the Correct HDB2/HDB50 Check Ball

Confirm Ball-Valve Family
Check that the pump belongs to the Heavy Duty Ball Valve range rather than a Heavy Duty Flap Valve configuration.
Select Material / Type
Identify the manufacturer-listed material and use a weighted designation only where Sandpiper specifically identifies one.
Verify Part Number
Match the selected check ball to the exact Sandpiper manufacturer part number in the applicable service manual.
