All these methods involve taking a measured amount of a chemical and then injecting that product into a pipe or similar vessel. A dosing pump will deliver this precise flow rate of chemical or other product by a number of different methods but it generally involves drawing a measured amount into a chamber and then injecting this volume of chemical into the pipe or tank being dosed. They are controlled either by an external control system or more commonly an internal pump controller that can alter the flow rate, the on/off function and also things like alarms and warnings for run dry, degassing and low product levels. The injector also has a spout so that the product is delivered into the middle of the flow rather than the side wall. This is a one way valve so that when the dosing pump pushes an amount of product into the line it can overcome the pressure in the delivery pipe and allow the product out into the flow. Flow Technology offers a wide range of hydraulically actuated Double diaphragm pumps.The design of the pump head ensures that the diaphragm cannot be damaged under critical conditions such as a blocked pipe or closed valves upstream or downstream of the pump.The freely defl ecting diaphragm makes the pump suitable for the metering of slurrieS. PLUNGER PUMPS DOSING PUMP • Low investment costs • Simple design • Easy maintenance DIAPHRAGM PUMPS DOSING PUMP: A leak-proof pump is the right choice whenever product purity or sterility are imperative or when toxic liquids must be handled. The injector. At the point at which the product is injected into the product, there is an injector point. The mechanics of the pump can vary (see below). hot water or super high pressure applications the line can be stainless steel. It should have a weight on it so it remains in the bottom of the drum of product and sometimes it has a float switch attached to it so the pumps has an alarm activate if the product runs out. چنانچه شما همین مقاله آموزنده را دوست داشتید و می خواهید اطلاعات بیشتری در آیتم دوزینگ پمپ مواد شیمیایی لطفا از تارنما ما دیدن کنید.
