The Jabsco 30530-2104 is a 316 stainless steel flexible impeller pump with a Viton impeller, tungsten carbide mechanical seal and 1-1/2 in NPT internal ports, supplied as a replacement pump head only, without a motor, designed to mount on a 184TC C-face motor. It is self-priming and debris-tolerant, with a nominal flow of 50 GPM (189 LPM). Use a NEMA 184TC frame C-face motor rated 5 HP at 1750 RPM with an appropriate service factor. The motor must handle high axial loads, ideally with the front ball bearing locked against axial movement, and deliver at least 14.5 ft-lbs forward and 43 ft-lbs reverse torque.
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: Can it run at variable speed?
Yes. These pumps suit single or variable speed operation, and running slower helps with thick or delicate liquids.
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.
