How liquid ring pumps work and what devices are used to control the operation of a liquid ring pump system for proper operation designing steam jet vacuum systems open file 220 12 kb description. The impeller forces this sealing liquid to the periphery of the pump casing where it forms a moving ring of liquid.

The klrc is a non pulsating vacuum. 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. Pump designed to remove gases through the use of rotating impeller blades that enter and leave a ring of liquid. Api std 681 liquid ring vacuum pumps and compressors for petroleum chemical and gas industry services.

Through our ongoing commitment to innovation product research and development nash continues to. This includes both vacuum pump and compressor design and system design. 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. A liquid ring pump is a rotating positive displacement pump.

The design technology behind liquid ring vacuum pumps is advanced to achieve optimum reliable performance for the rigorous demands of harsh industrial environments. Our liquid ring vacuum pump design was the first of its kind at the turn of the 20th century and has been an industry leader ever since. 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 following figure shows construction of a typical cone type vacuum pump.

In this design the cells between the impeller rotor blades are open around the periphery. Up to 10 700 m h suction pressure. Liquid ring vacuum pumps. 33 up to 1013 mbar.

Liquid ring vacuum pumps are designed in two different types. Cone type and flat plate type. Sihi single stage or two stage design for handling of gases and vapours. Nash liquid ring vacuum pumps are a reliable and durable solution for challenging process applications.
