API 610 is a standard developed by the American Petroleum Institute for pumps with end seals. The main fields of application of these pumps are petroleum and petroleum refining industries. However, the pumps can operate in any industrial sector where a high reliability and operating safety are required.

The standard sets strict requirements for the structural and material design of the pumps and their operating characteristics, such as:

  • service life and time between overhauls;
  • availability of replaceable wear rings for the body and the impeller;
  • reliability in wide ranges of temperature and pressure;
  • a maximum vibration level;
  • the shaft beat;
  • the pump test pressure;
  • the base frame structure.

Besides, the application of standard API 610 makes it possible to unify the pumps and pump assemblies made by different manufacturers.

As technologies and production processes advance, requirements for pumps are increased; therefore standards API are systematically verified and updated. We offer the pumps which are manufactured according to the latest revision of standard API 610. Our product line includes all the pump types under API 610: overhung pumps, multistage pumps and semisubmersible pumps produced in a wide range of operating characteristics.
