Every Primus Titan pump features a silica carbide mechanical seal face with FKM (Viton) elastomers and a PP (polypropylene) housing and impeller. The motor uses cold-rolled non-oriented silicon steel, and all wetted materials are saltwater-compatible. Q Can I use these pumps with ozone? Yes. The FKM (Viton) seal elastomers are ozone-resistant out of the box. No seal upgrades or material changes are required for ozonated aquaculture systems. Q What is the motor housing made from? The motor housing is silicon steel — specifically cold-rolled non-oriented electrical steel. This provides high magnetic efficiency and durability in demanding aquaculture environments. Q What does HO mean? HO stands for High Output. HO models deliver 45–50% higher flow because of their lower head compared to base models at the same power rating. Available in single-phase (220V) and three-phase (380V) with the same hydraulic performance curve. Q Unsure which model you need? Give us a call with your pumping heights, plumbing size/length/fittings, and required flow rate and we will run a friction loss calculation to size the perfect pump for your application. Q Are these pumps rated for continuous duty? Yes. Primus Titan pumps are rated for S1 continuous operation. The motors feature 30% more copper winding than standard motors for cooler running and extended service life. Q Do you offer trade or bulk pricing? Yes.
