The pump hoist shown here is one of the larger units. At the start of the pumping cycle, the follower plate is placed on the product manually using two push buttons, after which automatic mode is initiated. During the demonstration, it can be seen how the pump reacts to the level sensor held by the operator. Once the follower plate reaches the bottom of the bowl, it automatically goes back up to the initial position. The bowl can then be taken away.
