walrus tq200 water supply and pressure booster pump

If the pressure limit cannot the original setting within 2 minutes, the pump will stop and attempt to restart every 10 minutes until the function is deactivated.Īutomatic stop when flow stops:The pump will automatically cycle down as water usage decreases. Once the pump starts to operate, the pressure sensor will automatically detect the pressure limit. Dry-run protection: The pump will automatically shut down to protect against dry running. This ensures a stable water supply even though occasionally the output flow is over the capacity.

The pump will maintain a constant operating pressure at the pressure setting. The inverter controller (VFD) has a pressure sensor to detect down-stream pressure and adjust the motor speed to keep it at the required psi. VFD is varied by changing the frequency of the motor supply voltage which allows continuous process speed control.Product Features:The pump will start smoothly when water is consumed. Also known as variable speed drives (VSD). The Inverter controller is a variable frequency drive (VFD).

Preset Flow Rate : 300l/m 3 Bar Constant Pressure.

The VSD also allows for a soft start and stop which reduces the violent torque, therefore extending the life of motors. One of the main reasons why drives save energy is because they can change the speed of an electrical motor by controlling the power that is fed into the pump. A Variable Speed Drive (VSD) regulates the speed and rotational force, or torque output, of the motor. The special operating system makes our variable speed drive centrifugal pumps an appropriate solution in all cases where water flow rates do not ensure suitable operating pressures.

Walrus multistage centrifugal variable speed drive (also known as variable frequency drive VFD, VSD or Inverter Control) pressure booster pump system is suitable for distributing water under constant pressure & flow in residential housing, supermarkets, commercial buildings, resorts, complexes & industrial applications where the incoming municipal water supply pressure is inadequate.
