Biotech Systec ZHCR (Zero Hysteresis / Constant Run) Degasser Vacuum Pump with PCB Degassing Control System, Analytical, Dual-Stage (DST), Side Mounted, Variable 50-400 mmHg - Includes Pump, PCB and Air Bleed

Part Number: 9000-1921

This Degassing Vacuum Control System is designed for simple plug and play operation into most of our degassing chambers. Simply provide 24DC and the system will automatically provide vacuum to the specified vacuum level. Built in continuous head purges ensure that moisture and vapor are swept out of the pump to maintain consistent performance. An optional connector is available for LED error outputs.

This all new generation of pumps is characterized of being almost entirely silent – a remarkable upgrade from older versions. It’s also lighter and operates with less vibrations.

The DST Pump with PCB is a vacuum control system for use with degassing chambers. The system includes a dual stage (DST) vacuum pump and a Smart board controller to maintain vacuum levels. There is a connector for optional external LED indicators or error outputs. The prep versions are designed to handle high vapor loads from high flow rate chambers or fluids with low vapor pressure that will cause increased solvent pervaporation through the membrane.

PUMP CONTROL SPECIFICATIONS:

Power Requirements 24 VDC @ 0.75 Amp max. (< 5 Watts consumption average)
Temperature 50 o C or lower when run in ambient conditions (20- 25 o C)
Vacuum Sensor Calibration Accuracy Prep 80 mmHg +/- 5 mmHg Analytical 50 mmHg +/- 5 mmHg
Closed-Loop Control Setpoint 50 mm Hg absolute (analytical) or 80mm Hg (prep) pump runs at high RPM until near setpoint, then speed is varied to maintain a value of setpoint— load independent.
Errors Detected 1 – Pumpdown: Prep — Unable to reach 82 mm Hg in 10 minutes. Analytical — Unable to reach 52mm Hg in 10 minutes.
2 – High Vacuum: Prep — Vacuum > 110 mmHg for more than 6 min. in the running state (after pumpdown). Analytical — Vacuum > 82 mmHg for more than 6 min. in the running state (after pumpdown).
3 – Sensor Signal: Sensor Failure Detected Sensor signal >800 mm Hg or sensor signal <10 mm Hg.
