KAWAMOTO Package Booster Pump System

KFE-A/P

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

· 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 flanges are made from precision cast stainless steel to withstand heavy load and free from strain. By mainly adopting stainless steel, resin, rubber, and bronze for the portion contacting liquid make

· 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. Compact design with height less than 520mm so that it is installable in the space under the reservoir tank. Suction and discharge flanges are arranged on the same surface, and discharge pipe are

· 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.
