![]() ![]() PLANET 2050 is Cummins’ metrics-based sustainability strategy focusing on our operations, customers, and supply chain. ![]() Water is the primary medium through which we experience the effects of climate change – from drought to flooding. Cummins Water Works specifically aims to bring fresh water to 20 million people who will not otherwise have access to it. A problem this large requires coordinated action to effectuate sustainable, innovative and local solutions. Today, about 785 million people lack access to basic drinking water, and by 2050 at least one in four people will likely live in a country affected by chronic or recurring water shortages. The program focuses on being part of the collective action required to solve the growing global water crisis afflicting communities, with direct negative effects on health, education, gender equity and the growth of entire economies. These features are all absent on older shaft bearing versions of the shaft.Cummins Water Works is our multi-million dollar commitment to strengthening communities through sustainable water and addressing the global water crisis. Note : The 25120 shaft and bearing assemblies can be identified by the indentation machined into the shaft on the impeller end, the slightly undercut shaft in the key area which allows the seal seat to slide down the shaft to within 3/8” of the mechanical seal, or the lack of a snap ring groove between the impeller and the bearing closest to the impeller. Attempting to use the 25115 mechanical seal on an older shaft design will damage the shaft and mechanical seal which will cause a seal leak. The 25115 mechanical seal kit can only be used in either a P1722C pump or with a P1700 series pump that has been upgraded with the 25120 shaft and bearing assembly. The 25115 mechanical seal kit CANNOT be used on the standard P1700 shaft due to the design. Attempting to use the 15955 or 23799 mechanical seal with the 25120 shaft bearing assembly or in a standard P1700 pump will damage the seal and cause a shaft leak. This seal is an upgrade over the standard mechanical seal. Warning : The new 25120 shaft and bearing assembly can only be used with the 25115 mechanical seal kit which utilizes a pressed on seal seat. ![]() ![]() This seal kit includes a seal pusher that sets the proper height of the seal seat on the shaft.įor further information about this option and how to identify whether or not you have the seal upgrade, please click on the P1722C pump links and download the technical guide. Previous pump designs can be upgraded to this new design by utilizing the 25120-SHW shaft bearing assembly and the 25115-SHW seal kit. The pumps are equipped with a pressed-on silicon carbide seal seat and a new shaft and bearing assembly. The new P1722C pumps replace the P1722, P1722B, P1722X, P1722A pumps respectively. ![]()
