The high performance, durable pneumatically operated L80 has an adjustable pulsation rate and ratio to fit vacuum conditions in the milking parlour, pipeline or bucket milking system, and the needs of differing animal species. This vacuum operated pulsator is manufactured in tough, long lasting materials and functions without electricity. It is easy to install, meets the ISO standard for pulsators, and can cope with all difficult farm conditions. Reliability – Controlled Flexibility – Stability The pulsator is in many respects the most important part of your milking plant. It must maintain a constant pulsation rate and ratio, regardless of temperature, humidity and other factors. Based on its well proven design,L80 has features which give optimal performance, high reliability and maximal durability. This pulsator L80 has an adjustable pulsation rate to fit vacuum conditions in the milking plant. It is manufactured in tough, long lasting materials and works without the need of electricity. Pulsation rate and pulsation ratio Constant intervals between the changes in pressure are important to ensure rapid milking and good udder health. These changes are governed by the pulsation rate. The relationship between the length of the suction and the massage phase is an important factor for ensuring optimal teat treatment. This relationship is determined by the pulsation ratio. By replacing the pulse slide, other pulsation ratios can be achieved. pulsator L80 assures constant pulsation rate and ratio to give you maximal milking performance. Adjustable pulsation rate The pulsator must consistently maintain the same rate, delivering the same number of pulses each minute. Our pulsator L80 is supplied pre-adjusted to give 60 ppm at 50 kPa. If a lower installation vacuum is used, the pulsator can be re-adjusted to give the same pulsation rate. Deviation can be adjusted by turning the spindle. Adjustable pulsation ratio The pulsation ratio is define to be a compromise between the faster milk extraction possible and the minimum stress on the teats to avoid health trouble. L80 is designed to allow 3 different pulsation ratio: 60-40; 65-35; 30-70. Installations Most importantly, the pulsator L80 functions without electricity. This allows for easy installation, safe execution and the flexibility to perform under all environments and conditions.
