Our casting quality is completed to a high standard and quality checked, any components with risk of corrosion are painted in Marine Grade Paint for maximum corrosion protection.

Impeller and Nut is constructed in Brass for proven longevity and has superior wear and corrosion resistance.

Bearings are NSK Brand Single Row Radial Ball Bearings.

Shaft Seal is a Silicon Carbide / Viton / Carbon / 316 Stainless Steel Seal.

Pump Flanges cast with Extra Thickness added for better strength and come standard universally drilled in both Chinese Bolt Pattern (Table H) and AUS Standard Bolt Pattern (Table D) providing better flexibility whether you are installing a new system or replacing an old system, removing the need to modify existing pipework to suit either bolt pattern.

Our Sealing Method is a Silicon Carbide / Viton / Carbon / Stainless Steel mechanical seal which runs in its own enclosed sealed chamber which is lubricated by food grade white oil, this sealing method protects the pump in instances where it may run for extended durations of time without water “ran dry” without risking damage to the pump or seal. This innovative new sealing method is a superior sealing method due to the reliability and the little maintenance required, mechanical seals provide a 100% seal rather than the outdated gland packing method which constantly leaks or sucks air, mechanical seals are proven to increase longevity of the pump mainly by protecting the bearings from residual moisture which is a proven factor in premature bearing failure.
