Pressurized water supply pump
Estimated terminal pressure constant control (inverter), high head, 2-6 pump operation
Product description
①Multifunctional control
・If the same pump runs continuously for a certain period of time, the system automatically switches to the standby pump.
・Equipped with an operation time equalization control function to suppress unevenness in the operation time of each pump due to changes in water usage time and season.
・If trouble is detected, the pump automatically switches to the standby pump for backup operation and self-diagnoses whether the same malfunction occurs again with the retry function and self-determines the alarm output.
・The 2-tank circuit, the inflow solenoid valve circuit, and the 5P circuit with electrodes are standard equipment.
・A backup controller is available as a special specification to avoid water cutoff even in the event of a failure of the pump, inverter, or control board.
・"Function to limit the number of pumps in operation" is available as a special specification to temporary reduce the power supply capacity, such as when using an emergency power supply.
 ※When the number of pumps in operation is limited, unit control is also limited. And interlock function cannot be used.
・Equipped with a stainless steel vertical multistage pump SVM-e, the overall design including the control panel and anti-vibration (pump section) saves space.
③Designed for maintenance
・The cartridge-type mechanical seal and spacer coupling used in the SVM-e type pump allow for easy maintenance of the shaft seal.
・The operating time and total number of starts for each pump can be displayed as a convenient guide for replacing consumable parts.
・Alarm history display (Up to the last 5 times) is available for quick response in case of trouble.
④New water quality standard-compliant product
Stainless steel is used for the wetted parts, and all possible measures are taken to provide safer water as well as to prevent rusty water.
