General Information
This manual provides information about the installation, operation, and safety precautions of
Zaiput Flow Technologies laboratory scale Back Pressure Regulator (BPR-1000). We recommend
keeping this manual near the device for quick and easy reference.
The device is designed for the maintenance and use of a user selected value of back-pressure in a
flow system or batch vessel. The device has two methods of operation: “Set It and Forget It”,
“Pressure Relief” or “Adjustable on Demand”.

Principle of operation
This Back-Pressure Regulator compares the pressure of the process fluid (main stream) to a
reference pressure. Flow of the main stream is allowed only if its pressure meets or exceeds
the reference pressure. This reference pressure is set by charging the BPR with gas through the
valve on the top of the device.
