POFS – Fluid polymer system for online mode
The POLYMER ONLINE FEEDING SYSTEM (POFS) is a fluid-polymer solution appliance (Online Mode) producing super-effective, ready-to-use polymer solutions automatically. The system can also be used in Batch Mode. The polymer is injected directly into the closed mixer system by a PID controller using an eccentric-screw pump.
Using special inverter unit and a rotary pump the polymer parent solution and water are mixed to form a ready-to-use solution. The additionally installed reflux component for partial polymer solution flow guarantees optimal energy application at the inverter even when the solution flow volume varies.
The POFS is delivered as a self-contained unit fixed to a stainless steel frame. It includes all internal piping and wiring and a switch and control cabinet tested to VDE/UVV Guidelines. The only other operational requirements operation are water and electricity supply connection.
VERDOS offers both systems in different automation stages so they are custom-built to suit your exact requirements. As well as the features listed below, we offer you a variety of options to suit your requirements even better. We manufacture all the devices in a range of models. Please refer to the technical data sheets for further information.
The POFS PP is designed for fully automatic operation and can be operated in both online and batch modes. The built-in water flow controls (induction flowmeter and control valve) maintain constant water flow even when the mains water pressure varies. A booster pump maintains constant energy application at the inverter.
The polymer is injected directly into the closed mixer system by a PID controller using an eccentric-screw pump.
Overall unit control is effected via modern PLC system. At the touch panel all the parameters needed for optimal operation can be set and all process data can be monitored.
The POFS MC is designed for fully automatic operation and can be operated in both online and batch modes. The solvent water equipment with pneumatic valve and pressure reduction, particle flowmeter with minimum-contact switch as well as a downstream pressure booster maintain a constant water supply and energy application at the inverter.
The polymer is injected directly into the closed mixer system by a PID controller using an eccentric-screw pump. The water flow control built into the pressure line of the stock polymer pump guarantees a constant supply of stock polymer to the inverter unit. Overall unit control is effected via a modern PLC with a 2-line display. The polymer dose is set at the operating unit through a membrane keyboard.
