Product Features
This pump adopts a centrifugal impeller with high flow rate, high efficiency,and low noise.
Adopting high-quality bearings, stainless steel shafts, high-quality mechanical seals, no leakage,and long service life.
Application Occasions
HVAC supporting facilities such as air energy and solar energy;
Pipeline pressurization, pool water supply,and industrial equipment matching.
Usage Conditions:
·Medium temperature: 2-100℃
·Environmental temperature: ≤50℃
·Input voltage: 220V±10% / 50-60Hz
·Medium conditions: clean, free of solid substances,and non viscous
·Chemical properties: approximately neutral,non corrosive,non explosive The maximum ethylene glycol content is 30%.If transporting special liquids, please consult the manufacturer first
·Maximum system pressure: ≤10bar
·Minimum inlet pressure:
a.Liquid temperature at +50℃, minimum inlet pressure>0.05bar
b.Liquid temperature at +90℃, minimum inlet pressure>0.3bar
c.Liquid temperature at +110℃, minimum inlet pressure>1.0bar
Note: The above values are only applicable at an altitude of 300 meters. For every 100 meter increase in altitude,the inlet pressure of the water pump needs to increase by 0.01 bar, To prevent noise caused by cavitation,a minimum inlet pressure should be maintained.
