Description
Automatic Liquid Nitrogen Pump
Compared to traditional liquid nitrogen pumps, SYDP-C Liquid Nitrogen Pump offers advantages such as stable liquid nitrogen output and controllable flow rate. It adjusts pressure to control the liquid output flow rate, maintaining a constant and steady discharge. The pump comes with real-time liquid level display, low liquid level alarm, prohibition of discharge at low liquid levels, real-time pressure display, high-pressure alarm, pressure compensation, over-temperature protection, emergency pressure relief and RS-485 communication interface, allowing convenient integration with other products.

Structure
SYDP-C liquid nitrogen pump consists of the following parts: the panel, pump head, seals, inlet rod and housing, thermal management system, valves and sensors. The key components - the cryogenic pump head, the thermally isolated drive mechanism, and the robust sealing system - are all designed to operate across a temperature gradient of over 200°C while managing the phase change from liquid to gas.
