MMEI conventional Transfer pumps are most appropriate for ultra-high-lift applications. The Mini and Workhorse pumps will meet the majority of your conventional transfer applications. Both pumps are available in top and bottom feed versions and are designed for aluminum and zinc applications. The pumps can be driven by either air or the more controllable and economical electric motor. Unlike our competitor’s pumps, our risers are not structural members of the pump and can be easily replaced. The riser sits on a button located on the base and the riser clamp is attached to the motor mount with a bolt. The riser can be changed hot, limited down time.
