Direct connecting

KFED

Application

Direct connection to water main for booster

Feature

By pump section's high efficiency design and IE4 equivalent PM motor, the KFE type realized top class total efficiency in the industry.
Enhanced control panel improves operability, and adds new functions such like Eco-drive, Remote monitoring (necessary optional accessory).
Redesign figure and materials brings downsizing and weight down.
Quiet & energy saving: Water supply with less pressure fluctuation and low operation noise by 2 VFDs equipped with microcomputer for water supply.
Less impact to water main: Soft start and stop pump minimizes impact to the water main.
Clean water supply without red discoloration: Stainless steel, Resin, and Bronze materials are adopted for portion contacting water such like Pump, Valve and Pipes, thus, free from concern about rusting and red discoloration of water.
Water level control of Overhead tank: Combination with level relay (standard accessory) makes it usable to direct connection boosting for overhead tank & gravity water supply system.
Supply terminal for heater with switch: Labor-saving for heater installation with supply terminal for heater as standard terminal.
Inspection work switch: Inspection work switch showing the states of "during maintenance work" improve maintenance work efficiency.
Direct boosting function: In case power failure and pump stop, city water main pressure pushes water to pump secondary side through bypass.
Fully equipped component: As well as Low sound TEFC motor and DC reactor, cumulative operation timer and counter is equipped as standard.
Pump stop in small capacity: When water demand is small such like midnight, pump will stop. for equalizing pump load in each, when pump stop in small capacity, automatically carry out alternate operation.
Temperature detection: In case of temperature rising of water in the pump, it stops pump for protection.
