Common rules and regulations for pump manufacturers are:
API 674 contains the minimum requirements for performance, construction and design of reciprocating positive displacement pumps such as plunger pumps for use in areas such as the oil, gas and chemical industries.
API 677 describes the requirements for the gear units used and their dimensioning. Typical applications for which this standard has been developed are water pump systems in cooling towers.
API 671 and API 610 compose the requirements for the design and construction of couplings. Their observance should enable the safe operation of the machines over long periods of time. The standard is also intended to ensure the long-term supply of spare parts for the couplings.
API 614 describes the requirements for lubricating oil systems. The standard includes, among other things, the specifications for the system components as well as the measurement and control systems.
API 670 describes the requirements for the machinery protection systems (MPS). The systems ensure safe machine operation by measuring various quantities such as vibrations, temperatures and rotational speeds.
API 520 and API 526 define requirements for the process side safety valves in applications such as refineries or chemical process plants. The safety valves are designed to protect the reactors and vessels used from overpressure. The standard compiles the most important requirements for this. Externally heated containers are not part of the standards.
API 676 describes the requirements for lubrication oil pumps operating according to the displacement principle in the oil and gas industry.
The National Electrical Manufacturers' Association (NEMA) and the International Electrotechnical Commission (IEC) have developed numerous regulations and standards for electrical drives. They compose the requirements for electric motors, such as those used, for example, to drive pump systems.
URACA can take all current API, IEC or NEMA regulations into account in the design and manufacture of pump units. The common standards of material selection such as NORSOK, STAMICARBON, NACE MR0175/0103 or SHELL DEPs can also be implemented. Even country approvals such as SELO for China or KGS/KOSHA for Korea are no problem for URACA products. If you would like to know more about this topic, contact URACA now.
