Simplify is our way of making it easier for you to decide if this is the correct chemical injection pump for you. Make sure the wet materials are compatible with the chemical (use compatibility chart here), the pump can achieve the maximum pressure and flow rate, it can use the power source available and, the control is the one you need for your application. Anything else is "bells and whistle"

Don't lose prime anymore! Any metering pump user can tell you; the biggest headache is keeping the metering pump pumping. Other pumps lose their prime often, which interrupt the application of chemicals, without warning. 

With a double check valve in discharge and suction, and a unique membrane foot valve (no check valve), don't lose your prime!

Quick to install, easy to operate and very reliable metering pump. 

These high qualities and intelligently designed metering pumps are solenoid driven metering pumps that will reduce the time spent installing, maintaining and operating them in the field. Less time working on servicing the pump means more time for more productive tasks. With a facing forward design that simplifies maintenance, reduced footprint, and enhanced diaphragm endurance, #yamapump is the ideal device to optimize the service time and increase your productivity. They can directly replace any LMI pump.
