KAWAMOTO Package Booster Pump System

KB

Product code: KB

Application

Constant pressure 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

Low operation sound and silent operation design. Multistage pump, duplex casing and adoption of low noise motor realize silent operation sound.
Preventing water from discolor to red, Adopting highly stiff precision stainless cast steel for pump, check valve, and pipes in package unit, and bronze and resin materials used in pump parts prevent generation of red color water.
Constant pressure water supply. Controlled by optical pressure sensor and flow sensor, stable water supply is possible with less repetition of start and stop during water supply.
Compact design. Space saving design wih less installation area and low height.
High reliability. Safe system design composed from backup operation, retry function for just in case, standard adoption of TEFC motor strong against dust and humidity, and reliable operation control by microcomputer (exclude alone operation model) adoptin
Water hummer less check valve adopted. Shock absorber type stainless check valve dedicated design to this package unit prevents water hummer.
Optical pressure sensor adopted. Long time stable operation with contact less sensor which has no mechanical wear and fluctuation of pressure setting.
BL approved model is also available.
