Standard Features

  • Flow rates from 0.48 to 1932.48 gph per head
  • Operating Pressures up to 5802 psig
  • Variable eccentric drive for accurate, robust operation and a smaller footprint
  • Four frame sizes to cover a broad range of applications
  • PTFE multi-layer diaphragm with integral diaphragm rupture warning system is standard on all pumps
  • Liquid End Materials in 316ss and Alloy 20, additional materials available on demand
  • 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). This advance in pump design technology means a more reliable metering pump in every application
  • Metering reproducibility is better than ±1 % within the 10 ‐ 100 % stroke length range under defined conditions and with correct installation
  • Continuous air bleeding of the hydraulic oil chamber ensures reliable operation
  • Integral adjustable internal hydraulic pressure relief valve with features that allow for oil cooling during extended periods of process upset conditions
  • Excellent flexibility
  • The Evolution's modular compact construction allows for a wide range of applications
  • Up to five (6) metering units of identical or varying pump capacities can be multiplexed for the greatest application adaptability
  • A rotatable drive housing allows for installation of motor in a vertical or horizontal position to better meet specific footprint requirements
  • Custom designs are possible to meet a variety of application demands

Available Options

  • Electronic stroke control (4-20mA, BUS Interfaces, etc.)
  • Jacketed liquid ends
  • Diaphragm leak detection: Guage only (Standard), Pressure Switches, Pressure Transmitters, Suitable for Classified Areas
  • Check valve configurations: Ball (single and double), Cone type, Plate type
  • Custom painting per specification
  • Custom wetted materials (Hastelloy, Monel, Zirconium, etc.)
  • Flanged and threaded connections to meet most ANSI or DIN/ISO requirements
  • Pump selections for high or low temperature applications

* Capacities are based on operating pressures up to 1500 psig. Derate flow 0.5% for each 100 psig over 1500 psig.

** Motor horsepower is based on maximum flow rate at 1500 psig discharge pressure. For pressures above 1500 psig or flows lower than the maximum, consult the factory for horsepower required.
