Frequently Asked Questions

What is a Geolast diaphragm?

Geolast is an elastomer that holds up better than standard Santoprene when pumping chemicals that contain petroleum products, giving longer diaphragm life on harsh mixes.

When should I choose the Extreme Duty version?

Choose it if you spray oil-based or petroleum-containing chemicals that shorten the life of standard diaphragms.

What are the electrical specs?

12 VDC, up to 8.5 amps, 14 AWG leads 6" long with a 2-pin connector.

Does it fit the same plumbing as the standard 7812?

Yes. It has the same 3/8" FNPT ports and 60 PSI demand switch as the 7812-201-SB.

Can I pump fuel with it?

No. Do not use it with flammable or combustible liquids such as gasoline or diesel.
