KAWAMOTO Package Booster Pump System

KFE-T

Product code: KFE

Application

Automatic water supply from ground and underground reservoir
Water supply to buildings and factories
Condominium, hotel, hospital, and industry
Small regional drinking water
Other general water supply

Feature

By pump section's high efficiency design and IE4 equivalent PM motor, the KFE type realized top class total efficiency in the industry.
New type control panel brings new functions such as upgraded functions, improved operability, eco drive function, and remote monitoring (special option) (compare with previous models)
Energy saving drive. In accordance with the change in the amount of water used, the power consumption of the pump is reduced by the water supply method that inverter controls the rotation speed of the pump.
Stainless steel precision casting The pump casing and pipes are made from precision cast stainless steel so free from strain. By mainly adopting stainless steel, resin for the portion contacting liquid make it free from red water generation.
Expanded product line Adjustable pressure setting range is expanded up to 110m, so the selection range is also expanded more than previous KF2 type.
High responsiveness and High pumping performance. Adopted a new control method with quick pressure response and low pressure fluctuation. Redesigned impeller and guide vane provide silent, powerful, smooth water supply.
Compact and light weight for installation work improvement. Compact design with height less than 520mm so that it is installable in the space under the reservoir tank. Surface of suction and discharge flanges (in KFE-A/P series, 3.7kW or less model) is co
Heater terminal is attached. Standardly equipped with heater terminal. Easy attaching of heater.
Temperature detective function It has the function to stop the pump when the pump internal water temperature rises.
Unified dual frequency specification. It is available either in 50Hz and 60Hz. And also, either in positive and negative suction.
