The SS Geosub sampling pump is the most versatile single stage 12 Volt DC pump in the industry. Designed with all stainless steel components, the SS Geosub allows you to sample with confidence even in the harshest well conditions. The SS Geosub Pump operates with the Geotech SS Geosub Controller.

The SS Geosub Controller is designed specifically for use with Geotech's SS Geosub 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 powered generator with 1 gallon of gasoline can operate the SS Geosub Controller and Geotech's sampling pump at full power for up to 18 hours continuously (generally much longer runtimes can be expected as the controller is used to reduce water flow for low flow sampling). The DC to AC inverter can be used to power the pump using a 12 V car battery as well!
