HIGH EFFICIECY AND ENERGY SAVING, RELIABLE AND LASTING, LOW NOISE AND SMOOTH

DPR vertical cold and hot water circulation inline pump is a new generation product after years of production experience of our company. Flow range 4.5~18.5m3/h, head range lift 5~28m. Though CFD fluid simulation analysis, this design optimizes hydraulic design, improves hydraulic eifficiency; application of fluorine rubber roller improves the seal's high temperature resistance and reduces the aging rate. EPDM type O seal increases the life span of sealing elements. Totally closed air cooling engine, ip55 protection level, safer operation and lower noise.

PROFESSIONNAL DESIGN TO ACHIEVE RELIABLE AND LASTING SERVICE

MAIN ADVANTANGES OF DAYUAN DPR PUMP
  • SOLUTION TO ULTRA- LOW-VOLTAGE START
    Ultra tolelrant voltage operation, ulta-low voltage start.
    Ultra tolerant voltage offers users to use the pump under voltage 180v~240v. On peak demand for electricity, voltage fluctuates frequently and voltage decreases evidently, which might cause the start problem of the old I version. The new DPR pump has good solution to this prolem and starts properly when the voltage is 145V.
  • HIGHT QUALITY SURFACE TREATMENT
    All hydraulic parts are with electrophoresis treatment or made of rust resistant material.
    The impeller is made of 304 stainless steel,and the shaft flow passage components are with stainless fabricated shaft white the rest with electrophoresis treatment, to achieve excellent rust resistance and longer life span, and avoid secondary pollution.
  • SUPER HIGH EFFICIENCY AND ENERGY SAVING
    Users cost less on electricity comparing like products and more environment friendly.
  • LOW NOISE SUPER HIGH TEMPERATURE RESISTANT GREASE BEARING
    Bearings with low noise and radiating cover and 150^ high temperature resistant grease.
  • MECHANICAL SEAL WITH HIGH TEMPERATURE RESISTANCE
    Mechanical seal of fluorine rubber, resistant to 100P hot water.
  • IP55 ENGINE PROTECTION LEVEL
    Entire closed air cooling engine, with meticulous designed rear cover, up to ip55 protection level.
