ปั๊มหอยโข่ง EBARA ชนิดใบพัดคู่ รุ่น :CDA
PERFORMANCE CURVE SPECIFICATIONS
The specifications below qualify the curves shown on the following pages.
Tolerances according to ISO 9906 Annex A
The curves refer to effective speed of asynchronous motors at 50 Hz
Measurements were carried out with clean water at 20°C of temperature and with a kinematic viscosity
of = 1 mm2/s (1 cSt)
In order to avoid the risk of over-heating, the pumps should not be used at a flow rate below 10% of best
efficiency point.
Symbols explanation:
Q = volume flow rate
H = total head
