Tornatech JP3 JP3/380V-415V/20HP/3PH/50HZ Jockey Pump Controller NEMA 2 (UL Approved)

The Tornatech Model JP3/380V-415V/20HP/3PH/50HZ is a full-service electric jockey pump controller engineered specifically to maintain uniform hydrostatic pressure within high-capacity fire protection piping systems. Acting as a pressure-maintenance guardian, this robust 20 horsepower device automatically initiates a localized jockey pump to compensate for minor system leaks, actively preventing the primary fire pump from short-cycling or unnecessary activation under non-fire conditions. Configured for across-the-line full-voltage (Direct-On-Line) starting, it operates seamlessly across international 380V, 400V, and 415V AC three-phase power lines at a system frequency of 50 Hz. The entire assembly is managed by Tornatech’s proprietary iPD+ solid-state microprocessor platform, allowing precise adjustment of cut-in and cut-out variables via door-mounted navigation keys without opening the unit. Built into a heavy steel, red powder-coated NEMA 2 drip-proof housing, it contains an advanced stainless steel pressure transducer rated up to 600 psi, multi-tiered visual LED status diagnostics, and a door-interlocked padlockable disconnect switch for safe field maintenance.
