PVDF1/4PTFE-EX
Pneumatic membrane pump, PVDF body
Applications: Compatible with a vast range of chemicals. Recommended for use with acids and bases
Pneumatic membrane pump, PVDF body
Descriptive
Pump marking: Ex II2 GD IIB/IIC 95°C.
Construction materials
- Body: PVDF
- Membranes: PTFE
Specifications and advantages
- Pumps designed for the transfer of aggressive and/or viscous liquids. Plastic pumps are recommended for strong acids and for bases.
- Dry self-priming pumps. The priming height varies depending on whether the pump is dry or wet.
- Adjustable flow rate by adjusting the pressure and flow rate of the air (see the accessories).
- In case of dry running, the pump continues to run without overheating or wear. Metal pumps are significantly resistant to solvents, hydrocarbons, etc. If the delivery of liquid is stopped, the pump stops automatically without getting damaged.
