Centrifugal Pump
OBIL
Inline Pump
Purpose
- Circulation of heating and cooling systems, replacement for horizontal volute pumps, pressurization, and liquid transfer in industrial and agricultural applications.
Features
- Guarantees high efficiency and reliability.
- Shaft seal or impeller can be replaced without removing the pump casing.
- Flow speed is gentle and noise level is low.
- Motor and impeller shaft are easy to inspect, maintain, and repair.
- Can be installed either vertically or horizontally (application varies depending on horsepower).
- Does not require a vibration isolation stand.

Key Features of Built-in Inverter
- Individual inverter control function Controls the rotation speed with inverter. (can combine 3 inverters)
- Alarms An alarm is activated if the inverter, over current, waterlogging, high pressure, and low pressure sensor malfunctions.
- Select operating mode Set the operating mode according to the intended application. (heating and circulation)
- Save operating data Differential pressure control, temperature control, pressure control
- Powerful control functions Set the operating mode according to the intended application. (heating and circulation)
- Communication Inverter for each pump transmits and receives data.
- Automatic power failure recovery Once power is restored, it remembers the operating state and operates automatically.
- Emergency operation If the pressure transmitter fails, use the control panel to override and operate the system manually.
- Alternating operation Alternate operation according to the operation time setting of the main pump.
- Central surveillance Operating status is transmitted to the central control panel.
- Malfunction pump skip If a specific pump fails, the system automatically skips the pump and keeps the system operating.
- Self-diagnosis Increases reliability by monitoring failures and operating conditions around the clock.
- Waterlogger protection Prevents idling using a waterlogging sensor.
- Built-in MICOM Built-in 16-bit powerful CPU to execute faster commands.
