Lead-Lag Pump Alternation Control
All About Pump Control
Precision Digital features easy to use, and feature-packed devices that can satisfy a wide variety of pump control applications. They are available in 1/8 DIN panel mount, explosion-proof and NEMA 4X wall mount configurations.
The PD6000 Pump Controller and PD8-6000 Explosion-Proof Pump Controller are loaded with features like an informative dual-line 6-digit display, a 24 VDC power supply to power any level transmitter, and user-friendly programming without the need for a PLC. It can alternate up to 8 pumps to control the level of sumps, tanks, or wells. Learn more
The PD765 Pump Controller and PD8-765 Explosion-Proof Pump Controller have features including a huge 1.2 inch (30.5 mm) display that can be seen from afar, user-friendly programming, and a 24 VDC power supply to power the transmitter. 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.
NEMA 4X Enclosures
For wall mounting configurations, choose from a wide selection of NEMA 4X enclosures that can house from one to multiple pump controllers. They are available in plastic or stainless steel.
