Provide reliable alternating operation for four pumps with standard features that include:
HOA switches
NEMA 4X enclosure
Circuit breakers (1-phase) or overloads (3-phase)
Visual and audible alarm
Pump run indicator lights
Auxiliary contacts
Six level control floats
Six (6) float variable operation allows more multiple configurations to meet application needs
Alternates between four pumps to share the load
Use a three (3) or four (4) float operation to always run two pumps at a time where high flow is required (i.e., two lead pumps and two lag pumps)
Use a five (5) or six (6) float operation for true demand dosing and the control panelswill operate as many pumps as required (i.e., one lead pump and up to three lag pumps)
