Noncontact seal enables ultra-pure water pump
Yokota Manufacturing Co has developed a novel clean pump technology it claims provides particle-free cleanness with a novel noncontact shaft seal mechanism.
Centrifugal force removes gas and foam quickly
Novel degassing and defoaming equipment is ideal for the food industry.
This degassing pump, with an interlocked vacuum pump, extracts and discharges even dissolved gas in liquid with extremely high efficiency.
Its patented 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 liquid.
The separated gas is then drawn out by the vacuum pump.

Higher efficiency and output from sewage pumps

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.
(Model ASP-0510, when processing water at 20C at a flow rate of 25 litres/min or less).
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 0.06t/min.
and total head from 5 to 25m.
Models that meet sanitary specifications are also available.
This degassing equipment is capable of performing a wide range of tasks in processing applications including:; supply of deoxidised water to prevent water pipes or boilers from rusting; deaeration of foods and beverages; production of ultrapure water; degassing of gas-containing chemical liquid; degassing of liquid products before packaging to prevent overflow; deaeration of lubricants and hydraulic oil; deaeration of cleaning liquid to improve cleaning efficiency; and others.
Outstanding performance is also demonstrated in applications such as defoaming of various foaming liquids.
By 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 favourable results such as liquid homogenisation and reduced particle size.
There are no clogging problems like that with membrane type equipment, and no troublesome maintenance is required.
Moreover, 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 components.
Thus, use of ASP series degassing equipment greatly reduces costs of liquid processing.
