1. Introduction
YMB constant pressure frequency water pump is made of special frequency inverter, pressure tank, water pump, sensor, check valve and substrate. It can adjust pressure automatically to meet the users requirements of constant pressure water supply, keep the constant pressure of water supply network, and make the entire water supply system always maintain high efficiency and energy saving.

2. Function
 Automatic control function: Frequency conversion system makes constant pressure speed operation to water pump. Operating on the sensor directly. Easy to use.
 Protective function: overload, overcurrent, short circuit, phase shortage, low voltage adjust, motor grounding, stop working when shortage of water.

3. Application scope
Application: General family, Small high-rise, senior villas, hotel and some place where need constant pressure water supply or other places where have no water tower and have not enough pressure need to boost.
Using places: Top house need to under second pressure, places can not have water quality of secondary pollution. Place where not need to use water tower to boost pressure and other places have not enough pressure need to boost pressure.
Suitable temperature of the liquid: Use in cold weather (using temperature: 75ºC max), hot water (using temperature: 120 ºC max)
