  • Information including continuous working time, working temperature and medium is required to be pre-confirmed with professionals; pump cannot work with high temperature or corrosive fluids.

  • When pump is connected into circulation system, load current will be reduced to 70~85% of Max working current (opening outlet current).

  • The head means the Max vertical lifting height of water,the flow is 0L/MIN@max head.

  • The max flow rate means flow rate with no lifting height(according to the curve bellow)
