Twin Screw Pump with Defoaming Function (VQ-type)Defoaming Pump

Defoaming Pump for
Ultimate Self-suction

Defoaming Pump

A new twin screw pump with defoaming function [VQ-type] (PAT) !
One of the largest challenges in liquid transfer by a pump is
air got into the fluid, which harms quality and makes defectives.
Focusing on this problem, we posed ourselves a difficult question, "Can't wemake a pump that has defoaming function?" and moved forward in ourdevelopment with focus on "vacuum defoaming." The resulting VQ-type pump has
excellent defoaming performance and reliability, and its system enables defoamingtransfer with compact size.
Furthermore, by mounting a vacuum generation device to the conventional twin screw pump tocreate high vacuum, the pump allows self-suction of high viscosity liquids, which had not beenachievable with conventional screw pumps.
This is a breakthrough pump that enables defoaming while transferring liquids, which had been awaitedby many users annoyed by defoaming problems.
Of course, the features of conventional twin screw pumps such as non-contact, no shear, no pulsation andno stirring are succeeded to this new product.

RequestSystem implementation diagram

Mixing of air causes the metal detector to have erroneous sensing
and makes it detect acceptable products as defectives, which is beinga big trouble.
However, reducing sensitivity of the metal detector may result in
failure to detect the metals that should be removed.
Is there any way to overcome erroneous sensing without reducing thesensitivity?

ResultTankForming defects could be reduced to 1/20 by defoaming transfer witha VQ-type pump.
Furthermore, liquid leaking problem could also be solved thanks to
not having a mechanical seal in the VQ-type pump.

System implementation diagram

Due to high viscosity, cleansing cream and toothpaste are difficult to besuctioned by a non-contact pump. However, we would not like to use acontact type pump for fear of contamination problems despite its highself suction power.
Although we currently transfer the fluid manually, is there a pump which
generates no contamination and suitable for high viscosity fluid?
