Does the improved pulsation output from CoPulsation™ cause liner slap?

There are some who believe that a long C phase (phase where the liner closes) is required to slow the liner movement down to prevent the liner from slapping the teat. Those who believe that do not understand the movement of liners. The typical conventional pulsator provides a C phase that is in the 120 to 180 millisecond range. CoPulsation™ provides a C phase of about 60 milliseconds. If you consider the time it takes for the liner to move and the distance it has to move the resulting liner velocity is around 1/10th of a mile per hour (less than 1/10th of a km/hour). The velocity of a slap is well over 20 miles per hour (over 12 km/hour). Anyone who places their finger in the working liner of a CoPulsation™ Milking System can feel the gentle compressive massage and note that there is not slapping action. If you place your finger into the working liner of a conventional machine you will feel a pinch or a light crushing action on the end of your finger which soon becomes a painful continued sucking feeling from the pull of the vacuum and the inadequate rest phase.

Why havenít the other companies made a better milking machine?

That is a common question we are often asked. Many farmers donít understand why the other companies have not improved their milking machines when mastitis is still the most costly problem in the industry and so many cows have slow quarters, uneven udders and mastitis. The fact of the matter is that the other companies have been trying for many years to solve these problems and have been unsuccessful in designing a milking system that provides the performance of the CoPulsation™ Milking System.

Their attempts are documented in numerous patents for products claiming to solve such problems as liner crawl, incomplete milkout, teat irritation, and damage to the teat/udder. You can read several examples of these on this site at the Known Problems page. The companies that make conventional milking systems like yours have actually documented the fact that your milking system causes these problems! Wouldn't it be nice if they had told you?

What makes your product different?

We are often asked what is different about our product. Simply put, it is the only milking machine on the market that provides a true massaging rest phase. All other systems provide a reduced milk phase in the form of a pinching action of the liner. The CoPulsation™ Milking System removes the vacuum from the teat canal and massages the full length of the teat thus preventing the typical problems of liner crawl, pain, teat damage and ultimately mastitis.

How does it work?

The CoPulsation™ Milking System is unique in that it requires two independent solenoids to control the fresh air and the vacuum. One solenoid controls the vacuum and the other controls the fresh air inlet. The fresh air enters a .5 inch diamter hole (about 16 times larger area than conventional) and does not have to squeeze around the plunger as it does in a conventional pulsator. This design creates an extremely efficient pulsation action that causes the liner to open and close differently than other milking systems. The liner fully closes below the teat canal and it massages the full length of the teat. The massaging action is very similar to the effect provided by support hose socks worn by individuals with poor circulation in their legs. This liner action enables proper blood and fluid flow in the teat during the rest phase so that the teat is not swollen and reddened upon removal of the machine. Your milking systems literally sucks continuously on the teat and canal throughout the milking process causing swelling, liner crawl and the break down of the canal resulting in scar tissue formation.
