This defoaming/degassing pump, with an interlocked vacuum pump, extracts and discharges even dissolved gas in liquid with surprising efficiency.

Degasses liquid mechanically without using any chemical additive such as hydrazine. Therefore it is safe, does not cause contamination, and greatly reduces maintenance costs.
We also manufacture pumps that meet sanitary specifications.

Principle of degassing (PAT.)

DP type ASP type

When pumping liquid flows through the orifice into the intake part of the pump, the dissolved gas in the liquid is separated from the liquid by decompression, and the generated gas-liquid mixture is fed to the inducer.

The liquid in the gas-liquid mixture is pushed against the periphery and stratified by rotation of the inducer, and the gas accumulates in the central area of the casing at the same time.

The gas remaining in the liquid is further separated from the liquid, as such liquid stratum is broadly exposed to high vacuum.

The gas is then drawn out by the vacuum pump through the impeller.

Any remaining liquid in the gas drawn out by the vacuum pump is separated by the impeller, and returned to the intake side of the inducer.

The outstanding degassing power is evident by the reduction of dissolved oxygen from a near 8mg/L at the intake side (raw water at 20 degree C) to 0.5mg/L or less at the outlet side.

The "YOKOTA Defoaming/Degassing Pump ASP type" received the 19th Nissyoku Excellent Food Machinery/Material Award in the machinery category.

The 19th Nissyoku Excellent Food Machinery/Material Award ceremony, established by the Japan Food Journal Co. Ltd., was held September 9th, 2016 in the Dai-ichi Hotel, Tokyo (Tokyo Minato Ward, Shinbashi) where the company's Defoaming/Degassing Pump ASP Type received the award in the machinery category.

The Nissyoku Excellent Food Machinery/Material Award was established by the Japan Food Journal Co. Ltd., in 1998, aimed at the development of machinery and robots supporting the food industry and materials industry, and to reward and show appreciation for their contributions, with this year being the 19th time that the award was presented. The target products include all machinery/robots, intermediate materials/sub-intermediate materials, and the software utilized by them, which are useful to the quality improvement of food products and support the food industry, such as food product-related machinery/robots/apparatus and their software, intermediate materials/sub-intermediate materials for packaging containers, food additives, essence, food ingredients, and functional raw materials. The awards are decided by a selection committee made up of representatives in various food industries and academics who discuss with and consult each other in reaching decisions.

The company's "Defoaming/Degassing Pump ASP Type" enables the instant and continuous removal of wasteful bubbles and gas occurring in the food product manufacturing process, and it has been credited with contributing to the improvement of product quality and production efficiency, which led to it winning the 19th Nissyoku Excellent Food Machinery/Material Award in the machinery category.

YOKOTA's proposal: Troubled with stubborn bubbles ? ........ The ASP type pump is the solution to the problem.

What if the ASP type pump, originally designed for degassing, is applied to defoaming ?
As expected, the defoaming tests have proven excellent defoaming performance as indicated below.

II. Examples of defoaming test

Defoaming test equipment (ASP-0310 3.7kW-2900min-1 / water ring vacuum pump 3.7kW)

Defoaming test equipment (ASP-0310 3.7kW-3000rpm / water ring vacuum pump 3.7kW)

Test results with various kinds of liquid are shown in Fig.1-Fig.3.
Curves on the left side of each figure show the relation between flow rate and total head, which vary depending on gas amounts (0%, 50%, 60%, 70%).
A curve on the right side of each figure shows the relation between the gas amount (%) at the intake side and the gas amount (%) at the outlet side.
Calculation of defoaming efficiency is as follows:
For example, if the gas amount is 70% at the intake side and 20% at the outlet side, then,

Defoaming efficiency = 1 - (Gas amount at outlet side / Gas amount at intake side) = 71.4%



Fig.1 Defoaming of normal water

Defoaming, Degassing Pump, Degassing Equipment / Defoaming of normal water

The graph indicates removal of approx. 95-98% of gas bubbles from normal water.



Fig.2 Defoaming of green tea

Defoaming, Degassing Pump, Degassing Equipment / Defoaming of green tea

The graph indicates removal of approx. 92-95% of gas bubbles from green tea in a condition ready for consumption (tea powder dissolved at the ratio of 0.55g powder/80cc water).



Fig.3 Defoaming of detergent

Defoaming, Degassing Pump, Degassing Equipment / Defoaming of detergent

The graph indicates removal of approx. 67-72% of gas bubbles from detergent dissolved in water at 1% density. Despite the propensity of detergent to produce large quantities of difficult-to-remove bubbles, our degassing equipment performed well.


The above test results prove our degassing equipment's surprising defoaming efficiency as well as its capability of continuous processing.


Moreover, YOKOTA Degassing Equipment enables remarkable cost reduction in the processing of various foaming liquids.

No clogging problems like that with membrane type equipment, no troublesome maintenance required, and the pumps easily meet sanitary specifications.

Time required to eliminate bubbles has been shortened, making it unnecessary to install a large tank for stabilization of liquid.

The stirring operation of the built-in impeller simultaneously provides favorable results such as liquid homogenization and reduced particle size.

With the self-priming and pressurized discharge capabilities, all processes including suction, stirring, defoaming and transfer of liquid are achieved in this single, compact pump, unlike conventional methods which require installation of several components.


Use of YOKOTA Degassing Equipment greatly reduces costs of liquid processing.


Equipment suitable for defoaming relatively large amounts of liquid is also available.
