The following items were reported by senior copy editor Jeannie Reall from Plastics Fair Dallas, held Feb. 13-15. LCI Corp. exhibited its new gear pump systems for high-molecular-weight high density polyethylene.
The EP-Series system uses a narrower gear profile with a larger shaft diameter to reduce gear shaft deflection in high-load conditions.
The combination can reduce bearing loading as much as 50 percent, according to Dan Smith, business manager, extrusion and compounding products, in the fluid systems division.
The system can replace a standard pump, as it has the same bolt pattern, he said.
Regional sales manager Dan Berger said that he expects to receive his second patent soon, for his redesign of parts for a gravimetric extrusion control hopper.
Socks used on standard hoppers can interfere with weighing. Berger eliminated the need for a sock by cutting the top of the acrylic cylinder at an angle, and cutting the material inlet flange correspondingly to reduce the gap to one-quarter inch.
Berger's first patent was for an LCI mounting system for an extrusion pump. LCI, formerly Luwa Corp., is in Charlotte, N.C.
