Variable Level Pump Switch

Single and double piggyback variable level switches for direct pump control

Features and Benefits

Zoeller Pump's variable level pump switches can be used to monitor liquid level conditions and activate dewatering, effluent, or sewage handling pumps used in non-potable water applications. The variable level pump switch is a convenient way of converting a non-automatic pump into an automatic pump. The standard pump switch is normally open when hanging vertically above the liquid level. When the water level rises and the switch is raised a few degrees above the horizontal position, the switch closes activating the pump. Normally closed models are also available for pump up applications. The float that encases the mechanical switch is constructed of durable PVC/polypropylene. Cord lengths of 15’, 25’, 35’, and 50’ are available.
