TECHNICAL SPECIFICATION

Stuart Turner reserve the right to amend the specification in line with its policy of

continuous development of its products.

Note:

For information on other voltages/frequencies which are not shown, consult any
supplementary instruction sheet supplied, or the rating label attached to the 
pump.

*Note:

Max working pressure is the maximum pressure that can be applied to the 
pump internal casing under any installation conditions.

**Note: In normal circumstances the temperature of stored water should never exceed 

65°C.  A stored water temperature of 60°C is considered sufficient to meet all 
normal requirements and will minimize deposition of scale in hard water areas.

Maximum permissible water temperature 65°C.
