Single Pump System (SPS)

flouride saturators

The SPS provides the most comprehensive ready-to-use, single LMI chemical-feed pump system available in the market today! The unit is designed to accommodate a single LMI feed pump and to provide either wall mounting or floor mounting of the entire assembly. In either case, secondary containment for chemical drips generated during preventive maintenance on the pump is a standard feature.

Applications include water treatment applications for industrial and municipal plants feeding all type of defoam-ers, disinfectants, inhibitor, oxidants, and other chemicals.


System Construction
Built of welded Polypropylene sheet for toughness, chemical resistance, drip containment and convenient mounting accessories. The equipment is very portable and very easy to start up out of the box.

On-board Piping
The piping layout includes a standard gas-trap design to prevent ingestion of any trapped air or gas found in the piping system. Ball valves are provided in the PVC piping with Viton seals (other materials available) along with a 100 mL calibration cylinder.

Chemical Supply
Configuration System may be fed with flooded suction or suction lift configurations. Consult system instructions.

Pump Mounting
The chemical feed pump can be mounted in any of three orientations: panel right, panel left or panel facing outward from the system for operator convenience.

Electrical Wiring
The system is provided with an on-board ground fault interrupter (GFI) for safely powering the pump and accessories. A receptacle and plug shield is provided for protecting the outlets when power cords are attached.

Control Accessories
Numerous accessories are available including: Digi-Pulse® flow verification sensors, ALM pump flow monitors (with visual and audible alarms for NO-FLOW), seven day-multi-event timers, pH-ORP control-lers, chart recorders, data acquistion systems, and more. Call NPI for additional options.

For single (SPS), dual (DPS) and multiple (MPS-X) pump and controller systems Call NPI for ordering information.
