Wall flange for hand pump (no. 4)

 

SKU: 050-236 • Brand: Other

 

This heavy-duty wall flange is a direct-fit mounting and sealing solution designed for 4" (No. 4) hand pumps and well pump platforms. It provides a stable, corrosion-resistant base for manual and cast-iron pump bodies, creating a vermin- and weather-resistant seal between the pump and well casing or mounting platform. Ideal for replacement parts, restoration projects, and farm or garden hand-pump installations, the flange is compatible with common 4" hand pump standards and four-bolt pump bases used across residential and agricultural well systems.

 

Key features

 

   
• Designed for 4" (No. 4) hand pump installations and standard four-hole pump connections.
   
• Robust construction—available in cast iron or plated steel options to resist outdoor conditions and mechanical wear.
   
• Works with common rubber gaskets, O‑rings, and bolt kits to create a secure, leak-resistant seal.
   
• Simple bolt-on installation: slip over casing, place gasket, orient pump spout, and tighten bolts uniformly to ensure vertical alignment and a tight seal.
 

 

Why choose this flange

 

Whether you’re replacing an aging flange or building a new pump stand, this No. 4 wall flange offers reliable mechanical mounting, sealing against groundwater and pests, and compatibility with common hand pump hardware. Use with a silicone bead or plumber’s putty where extra vermin-resistance is required, and check flange-to-platform clearance to accommodate frost heave or concrete platforms as recommended for long-term performance.

 

Applications & maintenance

 

Perfect for well houses, garden pumps, backup hand pumps and restoration of antique cast-iron pumps. Periodic inspection of the gasket and fasteners will preserve a watertight seal and prevent rust—replacing the rubber gasket or applying anti-seize on bolts extends service life.
