Sandpiper PB¼ ¼" Standard Duty AODD Pump Diaphragm for Non-Metallic Pumps
Genuine Sandpiper replacement diaphragms for compatible PB¼ ¼-inch Non-Metallic Standard Duty AODD pumps. Available diaphragm materials include Santoprene, Hytrel and PTFE according to the applicable pump configuration and manufacturer part number.
Product Overview
The Sandpiper PB¼ diaphragm, also searched as a Sandpiper PB1/4 diaphragm, is a genuine replacement wear component for compatible PB¼ ¼-inch Standard Duty air-operated double diaphragm pumps.
The PB¼ is a Non-Metallic pump available with polypropylene, PVDF or conductive acetal wetted construction. These materials describe the pump's fluid-contacting construction and are separate from diaphragm material.
Current Sandpiper PB¼ Design Level 4 service documentation lists Santoprene, Hytrel and PTFE replacement diaphragms. Confirm the pump identification, design level and existing diaphragm part number before ordering.
