Safety processes as standard.
The ORLITA Evolution 1S together with the ORLITA Evolution hydraulic diaphragm metering pumps EF1a, EF2a and EF4a form an integrated product range with stroke lengths of 15 to 40 mm. This covers the capacity range from 3 to 7400 l/h at 400 – 10 bar. A wide range of drive versions is available, including some for use in Zone 1 or Zone 2 areas at risk from explosion with ATEX certification. The ORLITA Evolution product range is designed to comply with API 675.
Your benefits
Maximum process reliability:
- PTFE multi-layer diaphragm with integral diaphragm rupture warning / signalling system
- Integral hydraulic relief valve
- The new diaphragm position control protects against impermissible operating statuses (e.g. no damage in the event of a blockage on the suction or discharge side)
- Metering reproducibility is better than ± 1% within the 10-100% stroke length adjustment range under certain defined conditions and with proper installation
- Continuous bleeding of the oil chamber ensures reliable operation
