Overview
Manufactured in the US, PI-R is Kay Industries' rotary phase converter that's a totally enclosed weatherproof unit that will produce balanced 3-phase power from a 1-phase supply from 1-100 HP. It is specifically designed for all types of irrigation and pumping equipment but is equally suited for any application in harsh environments where utility 3-phase is not available or too expensive to obtain.
The PI-R rotary phase converter is a rugged totally enclosed construction designed to give years of reliable outdoor service. The converter will run any combination of pivot motors, end gun, and submersible pumps simultaneously. All motors develop their full nameplate HP and will enable the pumps to deliver their rated flow. The Type PI converter is guaranteed compatible with variable frequency drives.
Besides the robust performance, the PI-R is far less expensive than alternatives such as generators or 1-phase motors and less costly than bringing in utility 3-phase lines. All converters and accessories are available in a few days as compared to weeks or months for a line extension. The rotary phase converter is also extremely efficient and so it may reduce overall energy usage of any given system it's added to.
The converter can be connected to any existing 230 or 460 volt 1-phase service. Installation is as simple as "2 wires in and 3 wires out" and can be performed in a few hours. The unit doesn't need to be bolted down making installation even easier. Occasional lubrication and overall inspection are the only required maintenance procedures.
The flexibility of the PI-R rotary phase converter is also empowered by the accessories that are offered for it, including automatic controls, a disconnect switch, surge protection, and a step up transformer. All rotary phase converters also come with a standard five year warranty and may be extended up to ten years at a nominal additional cost.
Key features of the PI-R:
- Lowest cost alternative
- Easy to install - low maintenance
- Self contained
PI-60-R PI-R Features
1. PI-60-R Automatic Controls
For unattended or cyclical applications, this accessory adds fuses, magnetic contactor, and timing relay to allow remote supervisory control or to start and stop the converter as demanded by the load.
2. PI-60-R Disconnect Switch
Accessory that adds fusible disconnect switch complete with time delay fuses supplied separately of factory mounted directly on the phase converter for local on-off control.
3. PI-60-R Surge Protection
Accessory that adds internally mounted lightening arrestors protect the converter from linear surges and other harmful transients.
4. PI-60-R Step Up Transformer
Accessory that adds single-phase dry type transformers to change 230 volt supply lines to 460 volts typically required for pivot irrigation systems.

- Lubrication
- Phasemaster converter bearings are pre-packed with a heat, moisture, and rust resisting polyurea based lubricant rated to operate in the temperature range of -35 to +350ºF. This initial charge plus a generous additional amount placed in the bearing housing during manufacturing is normally enough to last the lifetime of the bearing. Converters exposed to severe operating conditions of high heat, moisture, dirt or limited ventilation require periodic lubrication. To grease the bearings in a smaller converter not having grease fittings, remove the end-bells and remove the excess grease. Replace it with a generous supply of a compatible lubricant such as MOBIL Polyrex EM. To lubricate a larger converter, inject a small amount of grease slowly into the grease fittings. Do not use high-pressure equipment. Take care not to saturate the windings with grease over an extended time. Remember, this grease goes somewhere when it leaves the bearing. Lithium based lubricants are incompatible and may cause bearing failure.
- Inspection
- Inspect the converter periodically to verify the ventilation slots are clear. In dusty or dirty environments, remove the end-bells and clean the windings of excess grease, dust and debris.
