Polmac has been manufacturing sprayers for agriculture in Italy for more than half a century, with great care taken to protect the enviroment and the operators health Designing these sprayers has helped Polmac realize that the field requires acurate measurement, monitoring and management of the agrochemicals used in crop protection and the increase of crop yeilds. The purpose of Polmac's research has always been to find the best working solutions. In fact Polmacs equuipment allows you to quickly and simply achieve: Greater precision in the amounts applied, Greater safety of operations, Obsrevance of the strictest standards and excellent end result.
UNI EN ISO 9001 Quality Certification
Since June 2003 Polmac's quality system has been certified by the International Certification organisation TÜV in compliance with the provisions of UNI EN ISO 9001 : 2000. The Polmac company has been recognised as being in compliance with European and Onternational standards with certificate no. 50 100 2968 regarding the production and support of components, acceeories and machines for applying chemical products for spraying and crop protection.
NYLON FLOWMETERS
The tested and dependable production of axial turbine flowmeters was planned in a variety of 
different materials : Nylon, Aluminium and Stainless Steel
This type of flowmeter can guarantee control within the lowest tolerance.
The wide range of Nylon flowmeters was planned for measuring highly corrosive and aggressive liquids and liquids under low pressures.
TECHNICAL CHARACTERISTICS:
The Nylon flowmeters come in sizes from ½" to 4". They are made of the following materials: - Nylon body. - Supports (bearing & turbine) are made of 430 stainless steel. - Bushings and Supports are made of Graphite or Ceramic upon request. - Sensor bodies made from Stainless Steel and Nylon. - Sinusoidal wave sensors - Square wave sensors - The tollerance are less than +1%.
