Vacuum Pump Parts,Kits and Services

When a pump needs repair, or DuoSeal series pump parts are to be\r\npurchased, there are often possible short-term cost savings, and probable\r\ndelivery advantages, to buying Non-OEM repair parts. In addition, the water or\r\nsewage capability may have a well equipped machine shop that can manufacture\r\nvarious pump parts. Some do so effectively and save money in the process, while\r\nother facilities do so ineffectively and fare poorly in terms of pump, pump\r\nlife cycle costs and plant reliability.

Buying pump spare or DuoSeal\r\nseries pump parts on the basis of cost as well as delivery alone is\r\nnormally not the best advance for consistency focused pump users. There are\r\ndecisive functional factors to consider, other than price as well as delivery,\r\nwhen making the decision on whether to purchase OEM or non-OEM parts.

The use of non-OEM parts may influence the manufacturer\'s\r\nwarranty.

Non-OEM parts may not meet OEM routine specifications. Appropriate\r\nimpeller vane contours are tricky to copy, and delicate changes can have a\r\nsubstantial effect on pump performance.

Since non-OEM pump parts are often copied from worn OEM Parts,\r\nserious fits as well as tolerances on copied parts may not meet OEM specifications,\r\nwhich can lead to impulsive failures. For instance, if a shaft fillet radius is\r\ntoo small, it will augment the shaft stress concentration and could lead to a\r\nfatigue failure. If a shaft fillet radius is too large, it may obstruct with\r\nappropriate assembly stack up. Machining marks under a shaft lip seal may cause\r\nit to leak in process. Oversized ball bearing fits on the shaft can cause\r\nextreme pre-loads which drastically shorten bearing life. Non-OEMs do not have\r\nResearch & Development facilities, so they cannot keep up with the latest\r\npart changes.
