Shaft End Cover Components for Dry Valve Pumps

Last Updated: Feb 12, 2013 05:00PM EST
When building a dry valve pump and extra seal is needed, a dry valve pump while in the dry mode of operation creates an internal vacuum which effects the shaft seals ability to seal properly around the pump shaft, the extra seal is needed to prevent debris from entering through the shaft seal area. This seal arrangement is called a back-to-back seal and is common to all dry valve pump applications. When building dry valve pumps is should be noted that dry valve thrust plates and dry valve rings seals are required for optimum performance.

NOTE: The P7500/7600 is now offered in an integral gear shaft set for SAE "C" keyed (Part # ZE-0024L-3-**).
