Corcoran Pumps has been offering problem solver solutions Since 1957, R.S. Corcoran Company has been manufacturing Corrosion-Resistant Centrifugal Pumps for the Chemical Processing Industry, the Pollution Control Industry and OEM Marine Markets.

We fabricate pumps from plate material in 316(L) Stainless Steel, Carpenter 
20 Cb-3 (Alloy 20) and Mo-4, Hastelloy B-2/B-3, C-22 and C-276, Duplex Stainless Steel, Monel, Nickel, Commercially Pure Titanium and other metals.

We offer a complete line of HORIZONTAL Pumps (close-coupled, ANSI B73.1 dimensional) single seal, double seal, cartridge seal, or packing – each with SELF-PRIMER and/or Vortex (Recessed) Impeller option. Also, a complete VERTICAL line, with submerged bearings or CANTILEVER shaft design. In addition, we manufacture a series of industrial design 316(L) Stainless Steel and exotic alloyed SUBMERSIBLE Sump Pumps available in 1/2 through 2 HP and heavy duty 316 stainless steel (EXPLOSION-PROOF motors) SUBMERSIBLE sump pumps from 1 to 150 HP.
