July Newsletter: Double Diaphragm Pumps, Hollow Shaft Encoders

GRACO EODD Electrically Operated Double Diaphragm Pumps

GRACO EODD double diaphragm pumpsGRACO E-series electrically operated diaphragm pumps offer all the benefits of air-operated diaphragm pumps without the necessity for a plant air system.

EODD pumps can run dry without damage, run against a closed valve or line blockage without damage, make suction lifts from a dry condition, reprime after an interruption of fluid supply on the suction side, just like their air-operated counterparts and can also minimize pulsations without a separate dampener. EODD operating expense is greatly reduced (compared to AODD operating expense) due to the direct use of electricity to drive the pump instead of using electricity to compress air to drive the pump.

When cart mounted, the pumps can be used as “utility” pumps all around your plant, eliminating the expense of purchasing/installing/maintaining pumps for intermittent usages. GRACO EODD pumps offer reliable, flexible service and simple maintenance with fluid contact repair parts available in kits.

Hübner Giessen FGH(J) 40 hollow shaft encoders are now also available in inches.

Hübner Giessen FGH(J) 40 incremental encoders for hollow shafts are robust and versatile heavy-duty specialists for a wide range of different applications. They record the speed on standard, main and auxiliary drives in steelworks, rolling mills, mining facilities and port and crane systems. These encoders are now also available for direct mounting on shafts with diameters of ⅜“, ½“, ⅝“, ¾“, ⅞“ and 1”. They are therefore now even more suitable for use in the USA, Great Britain and other countries that prefer to measure in inches.
