Variable volume pump
The variable volume pump immediately responds to changes in the discharge line to provide optimum delivery of a liquid with changing viscosity.
The variable volume pump is part of the 220 Series of rotary piston pumps. The 220TV pump immediately responds to changes in the discharge line to provide optimum delivery of a liquid with changing viscosity. The 220TV reduces resistance to flow and eliminates pipe fittings in critical suction applications with the suction port. Because it protects itself without bypassing any liquid, the pump allows smaller drives. The 220TV's design is based on the positive displacement rotary piston pump principle and is designed with only three moving parts. It is equipped with 4-in flanged ports and an extra-long bronze shaft bearing. It is designed for high-viscosity liquids to 5,000,000 ssu with speeds matched to viscosity up to 2200 GPM.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
