VACUUM PUMP & CONTROLLERS FOR HPLC DEGASSING

Presenting the ZHCR® Zero Hysteresis - Constant Run stepper motor driven vacuum pump. This is the perfect pump for vacuum degassing of fluids containing organic solvents and really excels in vacuum stability, quietness and lifetime.

Systec Degassing Vaccum Pump 2
The ZHCR® pump is specifically designed and developed for membrane vacuum degassing of HPLC mobile phases and other mixed aqueous-organic fluids. Employing a micro-stepping RPM control strategy, permits the pump to run continuously, cycling between low and high speeds. The high speed provides quick pull-down, while the low speed sustains a consistent vacuum level.

Fluctuations in baseline due to vacuum hysteresis are eliminated by not having to repeatedly stop and start a single speed pump. This also greatly reduces wear and noise. The low wattage DC stepper motor runs quietly and coolly while also being very adaptable in its power supply requirements. The brushless motor is especially appropriate for an environment where solvents vapours may be present.

Flow path materials were chosen for their ruggedness and compatibility with exposure to organic mobile phase vapours. The need for a vent valve has been eliminated by the continuously purged head design and built-in anti-backflow duckbill check valves. The pump will start into a full vacuum, and vacuum will not be released in the event of a power loss. The entire pump assembly is compact in design.

  • Inert flow path
  • High vacuum level
  • Quiet stepper motor/ball bearing drive
  • Cool running DC motor
  • Long life expectancy at low rpm
  • Continuously purged two-stage PTFE diaphragm head
  • Built-in anti-backflow check valves
  • Compact in size
