Grundfos 00335021 Flange Set
The Grundfos 00335021 is a heavy-duty 2 inch NPT flange set designed for seamless integration with high-head centrifugal pumps and circulators. Engineered to satisfy ANSI 250# flange pressure ratings, these cast iron components provide the structural integrity required for high-pressure commercial hydronic systems. The kit facilitates a secure, leak-proof transition between NPT threaded piping and flanged pump housings, ensuring optimal flow dynamics and minimal vibration. Each GF 50 flange set includes the necessary hardware, providing a precise fit for Grundfos models where a robust pump flange kit is essential for system longevity. These flanges are critical for maintaining mechanical seal alignment and preventing stress on the pump casing in demanding HVACR environments. By utilizing genuine Grundfos pump accessories, contractors ensure that the installation meets original equipment manufacturer specifications for bolt pattern alignment and load distribution.
- ANSI 250# Rated: Built to handle high-pressure hydronic applications beyond standard 125# residential components.
- Precise 2" NPT Connections: Ensures a clean, threaded interface with standard schedule 40 or 80 piping.
- Cast Iron Construction: High-density material provides superior resistance to thermal expansion and mechanical stress.
- Complete Hardware Kit: Includes industrial-grade bolts and nuts to facilitate immediate field installation.
- Direct Compatibility: Engineered specifically for Grundfos pump housings to eliminate alignment issues and gasket failures.
Common Questions
What is the maximum pressure rating for this flange set?
The Grundfos 00335021 is rated for 250# ANSI service, making it suitable for high-pressure commercial heating and cooling loops where standard flanges would fail.
Does this set include gaskets for the pump interface?
Yes, this 2 inch NPT flange set is a complete kit designed to provide a watertight seal between the pump volute and the piping system.
Can I use these flanges with other pump brands?
While these are Grundfos 2 inch flanges, they may work with other pumps utilizing a standard 2-inch bolt pattern; however, verification of the bolt circle diameter and flange thickness is required for non-Grundfos applications.
