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.

Models

Model D Close Coupled

Direct-mounted Model D units are mounted directly to the motor rabbet through a stub shaft. The design is ideally suited for 6 pole,4 pole and most 6 pole applications. Motors are available through 75 HP in the TEFC enclosure. they are lightweight and eliminates the bearing pedestal.

Model D -SP Close Coupled Self-Priming

Direct-mounted Model D units are mounted directly to the motor rabbet through a stub shaft. The design is ideally suited for 6 pole,4 pole and most 6 pole applications. Motors are available through 75 HP in the TEFC enclosure. they are lightweight and eliminates the bearing pedestal. Corcoran self-priming pumps secure self-priming action through the use of priming chambers and an internal recirculation system. Liquid is circulated through the impeller resulting in a low pressure area which draws the air in the suction line into the pump. the combined air and liquid are circulated through the air separator where the air is separated from the liquid and the liquid is returned to the impeller to trap more air. The process is continued until the pump is fully primed.

Model F Pedestal Pump

Flexible-coupled units consist of a pump bolted to a bearing pedestal to which power is transmitted by a flexible coupling from a power source. Flexible-coupled units are required by many end users – 1) standard rigid base motor is preferred 2) C-face motors are not available 3) ease of motor replacement 4) certain electrical, mechanical or corporate code require a channel mounted, flexible coupled pump.

Model F - SP Pedestal Pump Self Primer

Flexible-coupled units consist of a pump bolted to a bearing pedestal to which power is transmitted by a flexible coupling from a power source. Flexible-coupled units are required by many end users – 1) standard rigid base motor is preferred 2) C-face motors are not available 3) ease of motor replacement 4) certain electrical, mechanical or corporate code require a channel mounted, flexible coupled pump.

Model DVL In Line Vertical

Pipeline mount or supported by an integral mounting plate; available with all sealing arrangements and materials of construction.

Model VE / Model VEC Vertical Sump

Corcoran supplies a wide selection of pumps with vertical extended shafts in two basic styles. Model VE pumps provided with submerged bearings and Model VEC – vertical cantilever shaft pumps with all bearings above the mounting plate and no rubbing parts in the fluid being pumped.

Model US- RX Explosion Proof Submersible

Commercial submersible centrifugal sump pump: abrasive resistant extra heavy duty for hazardous location with explosion- proof motor design for erosive/abrasive slurry/sludge transfer service. Motor sizes from 1HP to 150 HP.

Vortex Pumps

A recessed impeller removed from the fluid flow path. Vortex impellers are used when pumping liquids with solids in suspension which cannot be degraded by impeller contact or with solids in solution or suspension which will erode a standard impeller. The recessed vortex impeller creates a whirlpool or vortexing action which swirls the solution into and out of the pump casing with no appreciable impeller contact.

Nuclear Waste Cleanup Pumps Heavy Duty Submersible

Corcoran provides submersible sump pumps and commercial horizontal pedestal mounted pumps for erosive/abrasive slurry/sludge transfer service. Water, radioactive with uranium and other main constituents in suspension.
