Features
- Flap valve pump can handle solid parts virtually at the same size of the suction port
- Non-metallic construcion (GFPP body)
- Suitable for liquids which contain large and irregular particles
- Top-suction / bottom-discharge design to easily handling of solid parts: the gravity force helps to keep clean the flap valves
- Advanced and efficient air valve
- Self priming and dry run ability without damage
- Easy access to the flap valve (bolted cover valve for a rapid inspection)
- In line maintenance without removing the pump from installation
- Clamped construction for a quick disassembly
- Good abrasion resistance
- Main applications: slaughtering, mining , steel mill, livestock farm, waste water treatment
