Geotech Geopump Peristaltic DC Pump, Two-Station, Dual RPM

Two pumping stations. The first pumping station has a variable speed of 30 to 300 rpm. The second pump station has a variable speed of 60 to 600 rpm. Each station can be piggy-backed with additional pumping head (sold separately) for multiple-station pumping. Variable speed Peristaltic Pumps are exceptionally durable to withstand field work and deliver up to 1.67ml per revolution. The pump head opens by lifting a lever. There’s no threading required to install, remove or change tubing. Samples only come in contact with the tubing to preserve sample integrity. Pumps operate to a depth of 27’ at sea level and offer a reversible flow feature you can use for back flushing. Each measures 8”H x 8”W x 3-1/2”D and includes a power cord. 12V battery and tubing sold separately.
