Simple MaintenanceException for the single-stage pumps with small
capacity and low head, all other pumps havea horizontally-split casing and the suction anddischarge nozzles are cast as an single integrated
unit along with the lower casing. So, interior
inspection can be done without removing thepiping and maintenance can be carried out easily.

Handling High Temperature WaterThe pumps are designed to handle hightemperature water above 100℃. They havea jacket around the stuffing box and bearing
housing to extend the service life of the glandpacking and ball bearings.

Sealing Water
When 2 pumps are installed, and one is used as aworking pump and the other as a stand-by pump,
air will enter the stand-by pump through thestuffing box, impairing the performance of theworking pump. In order to prevent this, sealingwater pressure is fed from the common dischargeline to the pump’s stuffing box.

NPSH
In order for the pump to be operated safely withoutcausing cavitation, the available NPSH must be greaterthan the required NPSH of the pump. The required
NPSH at the design point is shown on the right chart.
The available NPSH must be set giving a sufficientmargin for the required NPSH.
