Main Products    Canned Motor Pumps    Sefety Monitor system



The one of weakness of canned motor pumps is the difficulty of the recognition of rotation direction since the rotating shaft is located inside of the pump. But Halla's bearing monitor can show rotation direction with green/red light on the bearing monitor. Also it can show the degree of bearing wear so that it enables

users to make easy maintenance.

Bearing is standard on all Halla canned motor pumps and can be used for both Mount on Terminal Box Type and Remote Panel Type according to customer's demand.


1) Motor protection in case of motor overheating in excess of thermal limit of wiring
Thermostat protects motor in case of allowing motor wiring to radiate excess heat.
2) Variety setting temperature by Halla thermostat type

3) Standard on all Halla Canned Motor Pumps


1) Standard on HT Type(Super Heat Resistant Type) that is capable of continuous pumping of high temperature fluids.
2) Optional for all models according to customer's demand


1) Load currents are detected by integral current transformers, and the internal solid state circuitry compares with preset underload. When the current level falls off below set point, red LED illuminates and after the preset delay time, internal SPDT relay switches output contacts.


2) Advantage
- Under-load protection / Dry-run protection
- Visual trip indication(LED)
- Definite Trip Time Characteristic
- Manual(Instantaneous) / Electrical(Remote) Reset
- Ambient insensitive
- Shutdown motors when unloaded
- Non-fail-safe Operation
