Repeater Relay Chemical Pump - Econ Integrator™ Series From Stenner



Repeater Relay Chemical Pump - Econ Integrator™ Series From Stenner

The Econ Integrator™ Repeater Relay Chemical Pump provides proportional injection for water treatment on livestock farms without the expense of additional equipment.

The Integrator is an efficient, compact pump and has cULus for indoor and outdoor use. The pump has a water meter operational mode that is time adjusted to accurately inject a fixed amount of chemical per volume of water determined by the pulse rate of the water meter in use. A built-in repeater relay provides a dry contact output signal that replicates the same signal the pump receives. The relay feature is especially useful in livestock operations where an existing dry contact water meter is being utilized to tally water consumption to a controller. Water consumption, a key indicator for animal health is uninterrupted. The relay feature is also perfect for installations requiring multiple pumps, all of which can be activated by one dry contact pulse water meter.

The Integrator is economical; it doesn't require an additional water meter dedicated to chemical feed for water treatment. Quality water is proven to contribute to livestock health, production and maintenance of the water supply equipment.

Select the Econ Integrator™ for Water Treatment

  • Water and water line disinfection; pH adjustment.

  • Injection of nutrients and supplements into water lines.

  • Oxidation of iron, hydrogen sulfide or manganese.

  • Injection of polyphosphate solutions for corrosion and scale control on plumbing fixtures.

Unique Stenner Features

  • Patented quick release pump head for periodic tube replacement, without tools.

  • Inject common undiluted chemicals without harm to the pump; eliminate daily stock solution maintenance.

  • Solid one piece pump tube construction.

How It Works

Wire two of the Integrator leads to the water meter, connect another two leads to the house controller, plug the pump into a receptacle and install an injection point in the pipe. The pump is equipped with a safety lockout feature and a standby mode. While in the standby mode the pump is inactive and the relay will continue to register water consumption to the controller when the pump has power applied to it. The standby mode also allows tube replacement in the pump head without disconnecting power and/or the lead wires. The pump has a 20:1 turndown ratio in 1% increments adjustable by a digital keypad with a backlit LCD screen.
