Function

Applications:

Suitable for pumping clean water and other liquids with similar physical properties. Ideal for domestic water supply, automatic irrigation systems, small air-conditioning systems, and as a component in other equipment.

Also frequently used in sectors such as petroleum, chemicals, synthetic fibers, pharmaceuticals, and fertilizers, as well as for small boiler feed applications; suitable for transporting non-corrosive liquids.

Pump Features:

  1. Cast iron pump body treated with a special anti-rust process.
  2. Brass impeller (featuring brass casting or stainless steel inserts to effectively prevent impeller jamming after long periods of inactivity).
  3. AISI 304 stainless steel welded shaft (prevents shaft corrosion and subsequent leakage caused by prolonged water exposure).
  4. Maximum liquid temperature: +60°C
  5. Maximum suction lift: +8m (requires a foot valve at the inlet and a primed pipeline; the pump is not self-priming).
  6. High-efficiency bearings (maintenance-free/lubrication-free).
  7. Motor with copper windings (100% copper wire; true specifications).
  8. Single-phase motor with built-in thermal protection.
  9. Insulation class: F
  10. Protection class: IPX4
  11. Maximum ambient temperature: +40°C
