The Portable Pump is a device for collecting samples from various liquid sources. You can power this compact unit with several different batteries or power supplies. Among them are the Isco Lead-Acid Battery Pack, Isco AC Power Pack, or an external 12-volt DC source,such as a deep-cycle RV or marine battery. Two switches control pump action. The PUMP CONTROL switch is a four-position rotary type and controls direction of pump rotation. The SPEED CONTROL switch is a potentiometer which controls pump speed. Controlling the speed of the pump allows taking very low turbulence samples.
