BENNETT - Submersible Piston Sampling Pump

Bennett Sample Pumps have automatic reciprocating piston motors, operated by compressed air, that generate power for operating a double acting, piston fluid pump. Models for lifts up to 500 feet have one motor piston; Models for lifts up to 1000 feet have two motor pistons, providing increased power for operating the pump. All models have a differential ratio between the motor pistons and the pump to accomplish lifts using low pressure air from small compressors.
