Sandpiper PB-1/4 ¼" Standard Duty AODD Pump Check Balls for Non-Metallic Pumps
Genuine Sandpiper check ball replacement parts for compatible PB-1/4 ¼" Standard Duty AODD pumps with Non-Metallic pump construction. The pump construction identifies the compatible product family; select the actual check-ball material or type separately from the manufacturer-listed options below.
The Sandpiper PB-1/4 check balls form part of the pump’s wet-end one-way check-valve system. As the diaphragms cycle, each check ball moves against its valve seat to help control the direction of fluid flow. The correct replacement depends on the exact pump model, configuration, material and manufacturer part number.
Product Overview
The Sandpiper PB-1/4 check ball is a wet-end replacement component for compatible PB-1/4 ¼" Standard Duty AODD pumps with Non-Metallic pump construction using a ball-type check valve.
Correct seating between the check ball and check-valve seat is important to check-valve operation. During maintenance, check balls should be inspected for wear or damage and matched to the applicable Sandpiper part number.
Available check-ball options for this configuration include Santoprene, Hytrel, PTFE. Material compatibility must be checked for the pumped fluid, and pump size alone should not be used to select the replacement part.
