KAWAMOTO Package Booster Pump System

KF-R

Product code: KF-R

Application

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

Feature

A number of operation unit control type of KF2, performing from 2 units to 6 units rotary operation.
Easy maintenance due to the individual ball valve for each pump.
Reliable back up function. water supply suspension are avoided as much as possible with the backup functions that activate when there is pump failure, inverter failure as well as pressure transmitter failure and control PC Board failure.
Water level control system is compatible to twin reservoir and 5 electrodes, standardly integrating inflow valve control circuit and terminal for attaching heater.
Stainless steel precision casting The pump casing and flanges are made from precision cast stainless steel to withstand heavy load and free from strain. The connection section is mainly made of stainless steel, and resin, and the bronze components prevent
Adoption of low noise type TEFC motor. All models are equipped with a low-noise TEFC motor as a standard. Highly Resistant to insulation deterioration due to dust and moisture and has a long machine life.
High responsiveness and High pumping performance. Adopted a new control method with quick pressure response and low pressure fluctuation. With the high pimping performance of the high efficiency three-dimensional impeller, water supply is quiet, powerful
Compact and light weight for installation work improvement. Accomplished 45% reducing an inner volume in max. compared with previous model. Discharge direction is selectable in either right or left.
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.
