Evolution® Series


The ProMinent® Evolution Series meets the most exacting safety requirements as extremely robust hydraulic diaphragm metering pumps. They stand out thanks to the PTFE multi-layer diaphragm with integral diaphragm rupture warning system and unique diaphragm position control. Their modular construction offers excellent flexibility for countless applications.
The ProMinent® Evolution hydraulic diaphragm family of metering pumps form an integrated product range with stroke lengths of 0 to 40 mm. This covers the capacity range of 0.79 to 1,955 gph at pressures ranging from 5800 to 145 psig. The ProMinent® Evolution product range is designed to comply with API 675. A wide range of drive versions are available, including some with ATEX certification for use in Zone 1 or Zone 2 areas at risk from explosion.

Applications

  • Chemical process applications
  • Boiler feed and Catalyst feed
  • Petrochemical applications
  • Low flow - high pressure applications
  • Heavy industrial applications
  • Water and wastewater treatment
  • Sodium hypochlorite (Bleach) feed applications
  • Dye injections

Features& Benifits

Maximum process reliability

  • PTFE multi-layer diaphragm with integral diaphragm rupture warning system is standard on all pumps
  • Integral hydraulic relief valve
  • The exclusive Diaphragm Position Control protects the pump against operating faults (e.g no damage in the event of a blockage on either the suction or discharge side)
  • Metering reproducibility is better than ± 1 % within the 10 – 100 % stroke length range under defined conditions and with correct installation
  • Continuous bleeding of the hydraulic oil chamber ensures reliable operation

Excellent flexibility

  • The Evolution’s modular compact construction allows for a wide range of applications. The Evolution can be multiplexed with up to five (5) metering units of identical or varying pump capacities for the greatest application adaptability
