*1 Fresh water refers to tap water, industrial water or well water, with a temperature of 0 to 80C, a
pH of 5.8 to 8.6 and a chlorine ion concentration of 200 mg/L or less.
Contact EBARA regarding low-temperature liquid between -15 and 0C and high-temperature
liquid exceeding 80℃.
*2 Liquid that is not a slurry, not containing solid material (special specifications arise depending on
the property of the liquid)
The pump's total suction head is shown at a water temperature of 20℃. When the water differs
*3
from this temperature, and for particular hot water temperatures, suction performance is reduced.
Please discuss the situation with EBARA.
The tolerance value for voltage fluctuations is 5% or less, and the tolerance value for frequency
*4
fluctuations is 2% or less. For simultaneous fluctuations of voltage and frequency, the sum of
their absolute values is within 5%. However in either case, the motor's characteristics,
temperature rise, etc. are not in accordance with the rated values.
Fresh water (pH: 5.8 to 8.6) *1 cutting lubricant, cleaning fluid etc *2
-15C to 120C
Model EVMS/EVMSL pumps conform to the "Permeability standards for
water supply unit equipment" as per the Japanese Water Works Law.
