Pump Fed Central System – Interactive Guide

Featured System:
60/20 High Flow Level Master™
Model # 989108

“60/20” indicates 60-gallon day tank with refill rate of approx. 20 GPM

The 60/20 High Flow Level Master™ is a water driven chemical proportioner that will automatically refill the 60 gallon tank with ready-to-use chemical solution at a rate of 21.2 GPM @ 40 PSI.

When the solution in the tank drops below a pre-set level, the float valve triggers air-activated solenoids to start the water flow. Using city water pressure (35 – 125 PSI), this venturi injection system draws and blends chemical concentrate into the water stream to create an accurately diluted solution.

The system cycles continuously and a secondary fail-safe float prevents overfilling. Pump sold separately.

Ready-to-use chemical is pumped from the chemical room to applicators throughout the facility.

Looking for a smaller dilution and pumping system?

Model #989155

Lafferty offers a lower flow rate version of the system featured above. See #989106, which only includes one Satellite Mixing Station.

Alternately, the 16 Gallon Mini-Central System Complete includes all of the back-room components for a small Pump Fed Central System. 

It dilutes chemical at a rate of 5 GPM @ 40 PSI and pumps it from the holding tank to Foamers, Entryway Sanitizers, and other Pump Fed Applicators (up to 9 GPM @ 60 PSI). The compact design can be mounted on the wall, and is the perfect solution in remote areas or where floor space is unavailable.
