Our advantage

1. Excellent hydrodynamic performance

Adopt precision casting + 5-axis CNC machining, blade profile error ≤0.1mm, ensure hydraulic efficiency ≥92%

The surface of the runner is polished to Ra0.8μm, reducing turbulence loss and saving 15%~20% energy than ordinary impeller

Dynamic balance rating up to G2.5 (ISO 1940), vibration value < 1.5mm/s

2. Super corrosion resistance

304/316 stainless steel (optional duplex steel 2205), acid and alkali resistance, seawater corrosion resistance

Passed 2000 hours of salt spray testing (ASTM B117) and intergranular corrosion testing (ASTM A262-E)

It is suitable for harsh conditions such as sour crude oil and chemical medium

3. Long service life

Anti-cavitation design (NPSHR value optimization 30%)

The surface can be nitrided (HV≥1000) or tungsten carbide spray, and the wear resistance life is increased by 3 to 5 times

Bench test life > 30,000 hours (API 610 standard)

4. Modular compatible design

Support ANSI/API/DIN and other interface standards

Traditional cast iron/bronze impellers can be replaced without changing the pump body

A full range of closed/semi-open/open impeller types are available
