This degassing pump, with an interlocked vacuum pump, extracts and discharges even dissolved gas in liquid with extremely high efficiency
Yokota Manufacturing has launched a new type of degassing
equipment, the ASP series, for highly efficient and quick
degassing of gas-dissolved liquid.
The main part of this
equipment is a degassing pump with novel structure patented in
USA, UK, Japan, and elsewhere.
This degassing pump, with an
interlocked vacuum pump, extracts and discharges even dissolved
gas in liquid with extremely high efficiency.
mechanism comprising an orifice and multiple types of impellers
generates strong decompression and centrifugal force to
continuously extract and separate the dissolved gas from the
The separated gas is then drawn out by the vacuum pump.
The outstanding degassing power is evident by the remarkable
reduction of dissolved oxygen in water, for example, from a near
8ppm at the intake side to 0.5ppm or less at the outlet side.
This equipment degasses liquid mechanically without using any
chemical additive such as hydrazine.
Therefore it is safe, does
not cause contamination, and greatly reduces maintenance costs,
Models are available with bores from 25 to 40mm,
flow capacity from 0.01 to 0.06ton/min and total head from 5 to
Models that meet sanitary specifications are also available.
This degassing equipment is capable of performing a wide range of
tasks in industrial and laboratory applications including supply
of deoxidised water to prevent water pipes or boilers from
rustin, de-aeration of foods and beverages, production of
ultra-pure water, degassing of gas-containing chemical liquid,
degassing of liquid products before packaging to prevent
overflow, de-aeration of lubricants and hydraulic oil,
de-aeration of cleaning liquid to improve cleaning efficiency,
Outstanding performance is also demonstrated in
applications such as defoaming of various foaming liquids.
using this equipment, efficient defoaming can be achieved in
continuous processing, and time required to eliminate bubbles is
shortened, making it unnecessary to install a large tank for
stabilisation of liquid.
Also, the stirring operation of the
built-in impeller simultaneously provides favorable results such
as liquid homogenization and reduced particle size.
says Yokota, no clogging problems like that with membrane type
equipment, and no troublesome maintenance is required.
with the self-priming and pressurised discharge capabilities, all
processes including suction, stirring, defoaming and transfer of
liquid are achieved in this single, compact equipment, unlike
conventional methods which require installation of several
