Abstract

A new and improved diaphragm metering pump is provided with a modular removable drive assembly. The removable drive assembly provides rotation to an eccentric shaft within the pump and is disposed outside rotary bearings for the eccentric shaft and outside sealing elements containing hydraulic fluid in the pump housing.
In a preferred embodiment, a readily accessible mechanically activated hydraulic refill valve cartridge is provided to hydraulically balance the diaphragm. In a preferred embodiment, a push to prime air bleeder valve is provided permitting automatic priming of the hydraulic system without requiring disconnection of any valves. The pump is designed to interchangeably receive a number of diaphragm assemblies including an improved leak detection diaphragm and a double-sided leak detection diaphragm. In a preferred embodiment, a diagnostics window is provided permitting visual inspection of the operating condition of various valves connected to the hydraulic system.
