1 Bennett Sample PumpsSubmersible Piston Patent No. 4295801 Canadian Patent nos. 1166075 & 1187331 Portable and dedicated units Pumping lifts-0 to 1000 feet Infinitely variable flow rates inch & inch diameterpumps Stainless Steel Construction Compressed air or bottledgas operated Reels, tube bundles & wellcasing caps for completeportable & dedicatedsystemsBennett Sample Pumps , Box 7644 Amarillo, Texas 79114(806) Sample Pumps have automatic reciprocating piston motors, operated by compressedair, that generate power for operating a double acting, piston fluid pump. Models for lifts up to 500feet have one motor piston; Models for lifts up to 1000 feet have two motor pistons, providingincreased power for operating the pump. All models have a differential ratio between the motorpistons and the pump to accomplish lifts using low pressure air from small compressors.

Cycle rate is easily con-trolled by adjusting air pressure supplied to the PISTONWATER DISCHARGE TUBEWATER LEVEL INDICATOR contact PISTON Lip type seals provide cylinder wall cleaning Pumps may be operated in any position from horizontal to vertical. These Pumps willoperate submerged to great depths or above water with a drop tube attached to the fluid Sample Pumps may be used as portable units, capable of sampling multiple boreholes,or used in dedicated well systems. They are constructed to permit easy dis-assembly in the field forcleaning and replacement of pump seals and valves, using ordinary tools.
