The Jabsco 30520-4104 is a 316 stainless steel flexible impeller pump with a Viton impeller, tungsten carbide mechanical seal and 1 in ports, supplied as a complete motor pump unit coupled to a 1-1/2 HP, 115/230V, TEFC, 60 Hz motor. It is self-priming and debris-tolerant.
Stainless steel flexible impeller pumps are especially useful where self-priming is required and for viscous or air-entrained liquids, handling liquids up to about 20,000 cps where the materials are compatible. They suit corrosive chemicals, alcohols and solutions, inks, dyes, paints and pigments, and viscous adhesives. The Viton impeller suits hydrocarbons and solvents, gives up to 6 ft of dry suction lift and up to 22 ft when wetted, and the tungsten carbide seal is chosen for highly corrosive or abrasive liquids. The pump relies on the liquid for lubrication and must not run dry for more than 30 seconds.

Frequently Asked Questions
Q: What routine maintenance does it need?
Inspect and replace the impeller periodically, watch the seal for leaks, and keep the suction line airtight so the pump primes reliably.
Q: Why choose a tungsten carbide seal?
Tungsten carbide seal faces resist wear from abrasive particles and attack from highly corrosive liquids better than carbon/ceramic faces.
Q: How do I confirm chemical compatibility?
Check your liquid against compatibility data for 316 stainless steel, the Viton impeller and the seal materials. Contact our team with your liquid for help.
Q: Can it pump thick liquids?
Yes. At lower speeds it handles viscous liquids up to about 20,000 cps where the materials are compatible.
