Defines the minimum requirements for the basic design inspection testing and preparation for shipment of liquid ring vacuum pump and compressor systems for service in the petroleum chemical and gas industries.

Api std 681 liquid ring vacuum pumps and compressors for petroleum chemical and gas industry services. Up to 10 700 m h suction pressure. The following figure shows construction of a typical cone type vacuum pump. Liquid ring vacuum pumps.

Liquid ring vacuum pumps are an economical and robust solution engineered to meet specific customer requirements. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid. The design technology behind liquid ring vacuum pumps is advanced to achieve optimum reliable performance for the rigorous demands of harsh industrial environments. Close attention must be paid not only to the design of the ring liquid system but also to how it is integrated into the user s process.

They are typically used as a vacuum pump but can also be used as a gas compressor the function of a liquid ring pump is similar to a rotary vane pump with the difference being that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression chamber seal. The design of the system is critical to the successful operation of the liquid ring vacuum pump or compressor. 33 up to 1013 mbar.
