DP0070-1312-S6 Threaded Lower Housing, 316L Stainless Steel

The DP0070-1312-S6 is a threaded lower housing component designed for industrial pumps, likely AODD (air-operated double-diaphragm) or similar positive displacement pumps. Constructed from high-grade 316L stainless steel, it offers excellent corrosion resistance, making it ideal for applications in chemical processing, food and beverage, pharmaceuticals, and oil & gas industries where hygiene and durability are critical. The design features a central threaded port (protected by an orange plug in images) for fluid connection and an 8-bolt flange for secure mounting to pump bodies or manifolds. Key benefits include compatibility with sanitary and aggressive fluid environments, ease of installation due to threaded connection, and superior resistance to pitting and crevice corrosion compared to standard 304 stainless alternatives. Drawbacks may include higher cost than carbon steel options and specific compatibility limited to matching pump models (manufacturer unidentified, potentially Wilden, Sandpiper, or similar based on design). This unused open box item shows no signs of wear, with clean surfaces and intact protective plug, providing value as a surplus part. Advantages over competitors include robust build for high-pressure operations up to estimated 150-300 psi (based on flange style), though exact ratings require confirmation. Overall, it's a reliable spare for maintenance, reducing downtime in demanding settings.
