electricPTFEfor cooling water

As an extremely robust hydraulic diaphragm metering pump, the ORLITA Evolution E1Sa/E2Sa meets the most exacting safety requirements. It is characterised by its PTFE multi-layer diaphragm with integral diaphragm rupture warning / signalling system and unique diaphragm position control. Safety processes as standard. The ORLITA Evolution E1Sa/E2Sa product ranges together with the ORLITA Evolution hydraulic diaphragm metering pumps product ranges EF1a, EF2a, EF3a and EF4a form an integrated product range with stroke lengths of 15 to 40 mm. This covers the capacity range from 3 to 7,400 l/h at 400- 10 bar. A wide range of power end versions is available, including some for use in the Zone 1 or Zone 2 areas at risk from explosion with ATEX certification. The entire ORLITA Evolution product range is designed to comply with API 675. Maximum process reliability: Capacity range from 0.9 – 134 l/h, 260 – 30 bar 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) The metering reproducibility is better than ±1 % in a stroke length adjustment range of 10 - 100 % under defined conditions and with correct installation Continuous venting of the oil chamber ensures reliable operation
