When trying to find a new bonding material dispense system, one manufacturer tested a series of pumps — all of which leaked due to the abrasiveness of the bonding material. The manufacturer also had been attempting to manage shot size
manually with their previous system, and was not able to keep dispense consistent. The company searched for
a system that could accurately dispense programmed shot sizes while also eliminating the leaking issues they
had experienced with previous pumps. Graco provided a Check-Mate pump with SmartWare software, and the manufacturer is now able to automatically dispense shots of bonding material as small as one ounce without leaks.

endless energy efficiency
game of whack-a-mole, motors have historically always been one of the go-to moles. They’ve been in the spotlight since 1992. Over the past few decades, repeated efficiency laws have seen motor efficiency get whacked into tighter and tighter shape.
The changing landscape of hydraulic drives is leading many fluid power specialists to quickly adapt to using variable speed pump drives. Optimum utilization of these drives requires, in many cases, additional system design considerations.
After a brief introduction to the importance of gear pumps in internal combustion engines, as well as in the most diverse hydraulic applications, a calculation method was applied that allows for sizing with considerably higher delivery rates. Upon identifying and analyzing a traditional pump, along with two construction solutions of asymmetric gear pumps, we then compared their related performances.
