THE BAKER / MONITOR PUMP JACKS are low cost, high quality units used to reciprocate a pump cylinder. They consist of a helical gear speed reducer driving two pumping arms ( cranks ) which are connected to the sucker rod by two long pumping angles and a cross head. These jacks are V-belt driven by either an electric motor or a gasoline engine mounted directly on the jack. Compared to worm gear pump jacks, Baker's jacks deliver 50% more power to the sucker rod. All these models are shippable via UPS.
THE BAKER   ZA   pump jack is a heavier duty model designed for deeper wells, heavier loads, and up to 2 hp motor. The pump jack can be mounted on a hand pump or directly on the well pipe itself. A spring-held pump rod pin in the crosshead can be quickly attached or withdrawn. The motor mount is easily adjusted for the base of your electric motor or gas engine and your V-belt length. You can operate the ZA pump jack during a power failure by rotating the jack's pulley with auxiliary power.
SPECIFICATIONS:   Maximum pump rod load is 1,500 lbs   ZA jack is geared 
9 to 1   Stroke is 6" Maximum of 42 strokes per minute   Weight is 131 lbs

Monitor Baker pump jacks and Dempster pump jacks for gas and electric powered pumping of water wells using a cylinder and sucker rod. With a pump jack you can pump water from a well without needing a windmill or a handpump. Pump jacks are lift pumps that are powered by gas or electricity to stroke sucker rod up and down in a well to operate a cylinder at the bottom.
