It can alternate up to 2 pumps to control the level of sumps, tanks, or wells. Learn more

Forget about complicated wiring, installations, level switches, and unintelligible devices. Precision Digital Pump Controllers are an efficient and informative solution. Watch the video on how to alternate pumps with the PD6000 Pump Controller.


Applications

How to alternate pumps with the PD6000 Pump Controller

The PD6000 Pump Controller can alternate up to 8 similar pumps for applications where pumps are used to control the level of tanks, sumps, or wells. Alternating pumps helps extend the life of the pumps by evenly distributing the load among the pumps in service. In the application below, two relays are set up to alternate when an on/off pump cycle is completed. Two other relays are used for alarms.

Pump Controllers Key Features Overview

Check out this short introduction to the PD6000, 765, and PD8 pump controllers with integrated level displays. These pump controllers include features that allow for clear and convenient level monitoring as well as control. They are rugged enough to handle almost any application environment, including hazardous areas requiring explosion-proof approvals.

Sump Level Control with PD6000 Multi-Pump Alternation

See how the PD6000 Pump Controller alternates pumps in a lift station while monitoring the level. Using the dual-scale feature, the PD6000 will be displaying gallons on the upper display and height in feet on the lower display. Two relays trigger high and low alarms, and two others trigger the pumps that drain storm water.
