GEOTECH Geosub Pump Controller

The Geotech 81200035 is a 240VAC input controller designed for the Geosub 2 pump, featuring variable DC output for groundwater sampling. It is designed for field durability and includes an internal processor to save settings for up to 80 individual wells.  The Geotech Geosub Controller is designed specifically for use with Geotech's Geosub 2 Stainless Steel Pump. It provides a safe, conditioned variable DC output power from an AC power source. Built-in sensing gives the operator accurate and precise control over the pump during sampling events. An average 1000-watt gasoline generator with 1 gallon of gasoline will operate the Geosub Controller and Geotech's sampling pump at full power for 18 hours continuously. Generally, much longer run times can be expected as the controller is used to reduce water flow for low-flow sampling. An easy-to-use programmable user interface with a bright display offers precise control over flow rates during groundwater sampling events. Site-specific settings and conditions can easily be stored and recalled for more efficient, repeatable sampling events. Rugged construction and easy-to-connect cables make setup and portability a breeze.

Part Number: 81200035
Variable Voltage Output: Converts 200–250V AC input into a variable 0–46V DC output (up to 300 watts) to precisely control pump speed and flow rate.
Dry Run Protection: Features a user-activated protection mode that senses current levels; it automatically shuts down the pump if it runs out of water to prevent motor damage.
Programmable Memory: An internal processor allows operators to save and recall specific parameters for up to 80 unique wells, ensuring repeatable sampling conditions.
Digital Interface: Equipped with a 2-line, 16-character alpha-numeric display that remains functional in a wide temperature range, controlled by simple push-button navigation.
Rugged Portability: Housed in a heavy-duty case rated IP67 when closed (IP51 when open and operating) for protection against harsh field environments.
Low Flow Control: Enables extremely low flow sampling rates, down to 10 mL/min, which is critical for maintaining sample integrity. 
Applications:
Groundwater Sampling: Precise, controlled pumping of groundwater from wells.
Environmental Monitoring: Used by environmental professionals to sample contaminated or clean sites.
Low-Flow Sampling: The controller allows for precise regulation of water flow, critical for low-flow sampling protocols.
Field Operation: Designed to operate with portable AC generators (e.g., 1000-watt generators) for remote field locations.
