The wilo-crono gland pumps, manufactured from Dortmund (Germany) type wilo pumps, are designed for long term use in air conditioning facilities, industrial facilities, and large private and commercial properties. Service temperatures are drawn in such heating and cooling systems , Can be between -20 ° C and 140 ° C Therefore, Wilo selected high temperature DuPont ™ ®zytel80g14ahs protection coupled pump lantern to connect the motor-driven pump hydraulic. "Polymer parts can be more economical to manufacture and assemble than made Metal perforated plates, which are commonly used for such applications. Even without coating, they contribute to the beauty of wilo-crono pumps, "Detlef Jäkel, Project Engineer Gland pumps, wilo." Glass fiber reinforced nylon 66 , Combined with DuPont's excellent strength, flexibility and impact resistance properties are also maintained for a long time, despite the conditions required to submit today's heating and cooling system. The principle factor that we choose for the material is to choose from when the boot is made of zytel®80g14ahs For maintenance purposes and urging to go back and break the accessories used in the break without breaking down, even after years of use. "Under the guise of manufacturers and co-developers , Germany - Energy • Technik's multimedia resource library - Umstadt (Germany), working closely with Wilo DuPont and material selection. "We produce samples for DuPont after comprehensive mechanical testing, and we optimize mold processing, Managing Director physician Felix Schmidt. "This helps us reach the very economic cycle of producing surface structures that are exactly the same in quality and accurately fit parts."
