Function

Applications:

Suitable for conveying clean water; small-scale domestic water supply systems; automatic sprinkler and irrigation systems; small air conditioning systems; and use as auxiliary equipment.

Commonly used in sectors such as petroleum, chemicals, synthetic fibers, pharmaceuticals, and fertilizers, as well as for small boiler feed-water applications; designed for conveying non-corrosive liquids.

Pump Features:

1. Cast iron pump body treated with a special anti-rust process.

2. Brass impeller (featuring brass castings or stainless steel inserts) to effectively prevent impeller seizure when restarting the pump 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
