The Jabsco 30520-4003 is a 316 stainless steel flexible impeller pump with a nitrile impeller, carbon/ceramic 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 nitrile impeller suits oil-based products, gives up to 10 ft of dry suction lift and up to 22 ft when wetted. 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: When should I choose a different seal?
For abrasive or highly corrosive liquids, a tungsten carbide seal version is the better choice. Ask our team if you are unsure.
Q: How do I confirm chemical compatibility?
Check your liquid against compatibility data for 316 stainless steel, the nitrile 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.
