The high pressure diaphragm pump heads of the LEWA M800 series represent an extension of the M500 series with a discharge pressure up to 800 bar. Due to an integrated diaphragm monitoring system, in combination with a PTFE sandwich diaphragm, high process safety is ensured. High pressure diaphragm pump heads are available from Petrenee .
With this series of high pressure diaphragm pump heads, the use of zero-leakage diaphragm pumps, exceeding the present pressure limits of plastics diaphragms, is considerably economical than using metal diaphragm pump heads.
Following are the advantages of M800 diaphragm pump head series:
- Maximum pressure 800 bar
- Temperature range –20 °C to +80 °C
- Hermetically tight system
- High process safety due to diaphragm monitoring system
- Long diaphragm service life
- Low life cycle costs due to wearfree plunger seals and long diaphragm service life
- Suitable also for difficult fluids e. g. suspensions with hard particles for fluids with high viscosity
- High suction ability due to diaphragm position control
- Safe against high suction pressure by full rear diaphragm support
- Safe against overload of the pump by integrated pressure limiting valve in the hydraulic part
Following options are available with the M800 diaphragm pump head series:
- Special valves
- A variety of connection dimensions
- Heating and cooling equipment
- Easy to clean pump heads (CIP)
- Hygienic designs for food stuffs, pharmaceutical and bio-technology applications
- Special materials
