The 3 Inch Mud Hog Replacement Diaphragm – Neoprene (No Holes) gives you the toughness of neoprene in a blank format you can drill to fit your specific pump configuration.

Why the 3 Inch Mud Hog Replacement Diaphragm – Neoprene (No Holes) Is a Shop Staple
Pump repair shops and rental fleets see a wide variety of Mud Hog 3″ configurations. Keeping a no-holes blank in stock means you are never waiting on a pre-drilled part that does not match the pump in front of you. You drill it to spec, install it, and get the pump back into service without delay.
The neoprene in this blank is the same quality as the standard version. Once drilled and installed correctly, it performs exactly the same way in the field. Clean holes placed at the right spacing are the key to getting full diaphragm life. The material holds a bolt hole well and does not tear easily if the holes are cut properly and not positioned at the very edge of the diaphragm.
Cross-Compatibility
The 3 Inch Mud Hog Replacement Diaphragm – Neoprene (No Holes) is made for Mud Hog 3″ diaphragm pumps that require a custom bolt pattern. If your Mud Hog 3″ uses a standard configuration, the pre-drilled neoprene version is faster to install and listed separately on our site. We also carry the rubber versions for this same pump and neoprene and rubber options for the Mud Hog 2″.
Frequently Asked Questions
What Pump Is This Blank Neoprene Diaphragm For?
The 3 Inch Mud Hog Replacement Diaphragm – Neoprene (No Holes) is designed for Mud Hog 3″ diaphragm pumps that need a custom-drilled hole pattern. Measure your old diaphragm carefully before you drill and mark all hole positions before cutting. If you are unsure whether this version or the pre-drilled one fits your pump, call us before ordering and we will help you figure it out.
How Is This Different from the Standard Pre-Drilled Mud Hog 3″ Neoprene Diaphragm?
The material and overall size are the same. The only difference is that this version comes without holes, which means you drill them to match your pump’s bolt pattern. If your pump uses the standard Mud Hog 3″ configuration, the pre-drilled version saves time. Use the no-holes version when the standard pattern is not a match.
How Does Neoprene Perform After Custom Drilling?
Neoprene handles drilling well when holes are clean-cut and properly spaced from the edge. The material is thick enough to hold a bolt hole securely and elastic enough to keep flexing through mud and slurry conditions without tearing at the hole points. Take your time drilling, use the right bit size, and the diaphragm will perform just as well as a pre-drilled part.
Does This Come in a Rubber No-Holes Version?
Currently, this blank format for the Mud Hog 3″ is available in neoprene. If you need a no-holes rubber blank or a different material option, call us and we will check what is available and whether we can source it for your application. Our team is happy to help you find the right part for a non-standard pump configuration.
