Product Overview

Tankless pump controllers greatly simplify installation and operation of rain harvesting systems while extending pump life.

When connecting a rain harvesting system to an irrigation system, it is no longer necessary to wire the pump into the irrigation control box. Instead, the pump controller senses the pressure drop when the irrigation valves open and then shuts the pump off shortly after the valves close. A delay is built in to prevent "hammering" - the on/off cycling that happened in the past.

Hose bibbs, toilets, urinals, pool top-ups and pond valves are controlled just as easily.

No programming is required. By default, the controller maintains approximately 50 PSI, however, an internal adjusting screw is provided to regulate other pressure level requirements.

Also features a brass plug that can be removed and used for the addition of a 1/4" water pressure gauge.

How it Works:

The pump controller’s function is to turn on the pump when demand starts and shut it off when the flow stops.  When flow stops (such as an irrigation valve closing, a toilet tank finishing its fill or a hose bibb being turned off, the pump controller applies several seconds of delay in order to avoid a common problem called “water hammer”. the concussion and accompanying noise that result when a volume of water moving in a pipe suddenly stops or loses momentum.

The cut-in pressure is the pressure at which the controller will turn-on the pump. So, if a pump’s maximum pressure is 100 psi at dead-head, the controller will turn off the pump when the flow is stopped. When water demand starts, the controller will leave the pump off while the pressure drops, and then it will turn on the pump when the “cut-in” pressure is reached. If the cut-in pressure is set for 50 psi (for example), that pressure will be maintained by the pump controller by turning on the pump every time the pressure reaches that low-pressure threshold.
