Diaphragm Type Metering Pumps

This article and video will walk you through the step by step process of replacing the flexible shaft in a Madden MF series diaphragm metering pump. The process is the exact same for the MH series pumps.

Replacing a flexible shaft is a quick and simple process, as are all repairs on a Madden pump. Madden Pump’s diaphragm metering pumps are not “throw away” pumps. They are industrial duty metering pumps intended for many years of service, with only occasional minor repairs ever needed. And because of that, we made sure our pumps could be easily repaired with common, everyday tools. We have built our metering pumps with quality, durability, and simplicity in mind for 60+ years and we are excited to continue doing so for years to come.

Watch the video to learn how replacing a worn out MP048 Flexible Shaft can be done in as little as 3 minutes.
