Corrosion-Resistant Pumps for Chemical & Industrial Applications

Cortrol supplies corrosion-resistant pumps engineered for safe, reliable operation in demanding chemical process and industrial fluid handling environments. Our pump offerings include sealless magnetic drive, air-operated double diaphragm (AODD), centrifugal, self-priming, vertical, multistage, and drum pump technologies from manufacturers with proven track records in corrosive service.

Pump selection in corrosive applications requires careful matching of wetted materials, hydraulic performance, and drive technology to the specific chemical, temperature, and flow conditions. Cortrol’s pump offerings are backed by technical support to help ensure the right pump is matched to the right application.

ANSIMAG

Sealless Magnetic Drive ETFE Lined Pumps

ANSIMAG (a division of Sundyne) manufactures sealless magnetic drive ETFE lined pumps specifically designed for chemical processing and downstream refining applications where safety and reliability are critical.

All ANSIMAG wetted parts are molded ETFE components capable of handling a wide range of corrosives and solvents at temperatures up to 250°F (121°C) without corrosion. A patented, fully encapsulated magnetic drive hermetically seals the inner magnets to isolate them from process fluid and maintain magnet integrity for the life of the pump. A Kevlar-fiber reinforced vinyl ester shell provides additional structural reliability.

Key advantages of ANSIMAG sealless magnetic drive pumps:

  • No seals, no leaks, no emissions
  • Energy efficiency
  • Drop-in replacement capability

Finish Thompson

Magnetic Drive, Centrifugal, Vertical, Drum & AODD Pumps

Founded in 1951, Finish Thompson manufactures a wide range of industrial pumps for corrosive and demanding fluid handling applications. Cortrol supplies the full Finish Thompson product line, offering pump solutions across multiple technologies and configurations.

Finish Thompson pump types available through Cortrol include:

  • Plastic mag-drive centrifugal pumps
  • Plastic self-priming mag-drive pumps
  • Plastic sealless multistage pumps
  • Vertical pumps
  • Sealed stainless steel centrifugal pumps
  • Drum pumps
  • Air-operated double diaphragm (AODD) pumps

This range of pump technologies allows Cortrol to match the right pump type, material, and configuration to your specific chemical, flow, and installation requirements.

RamParts

Heavy Duty Air-Operated Double Diaphragm Pumps

RamParts Pumps (a division of Andronaco Industries) manufactures super heavy duty, sealless air-driven diaphragm pumps designed for continuous operation with the most demanding fluids. Whether the application involves sludge, abrasives, corrosives, or any combination of the three, RamParts pumps are built for the punishment.

RamParts AODD pump specifications:

  • Size range: 1½” to 6″
  • Flows to 380 GPM
  • Pressures to 125 PSIG
  • Temperatures to 300°F
  • Air driven for intermittent or continuous duty
  • State of the art controllers for precise air management

RamParts pumps are well suited for chemical transfer, slurry handling, and abrasive service applications where conventional pumps experience frequent seal failures, excessive wear, or inability to handle thick or particle-laden fluids.

Where Pump Solutions Are Used

Corrosion-resistant pumps supplied by Cortrol are used across a wide range of applications including:

Chemical transfer and process circulation Acid, caustic, and solvent handling Wastewater treatment chemical feed Slurry and abrasive fluid transfer Drum and container emptying Tank loading and unloading Below-grade and sump pumping

Technical Support & System Integration

Selecting the right pump for a corrosive or industrial application requires careful consideration of:

  • Chemical compatibility and wetted materials
  • Flow rate, head, and system curve Temperature and pressure requirements Suction conditions (flooded, self-priming, below-grade)
  • Solids content and viscosity
  • Drive type (magnetic drive, air-operated, motor-driven)
  • Installation layout and space constraints

Cortrol provides guidance to ensure pump solutions integrate effectively with your broader piping, valve, and fluid handling system. The right pump selected in isolation can still underperform if it is not matched to the piping layout, suction conditions, and downstream components.

Pump Frequently Asked Questions

Cortrol supplies sealless magnetic drive pumps, air-operated double diaphragm (AODD) pumps, sealed centrifugal pumps, self-priming pumps, vertical pumps, multistage pumps, and drum pumps for corrosive and industrial fluid handling applications.

Cortrol partners with ANSIMAG (a division of Sundyne), Finish Thompson, and RamParts Pumps (a division of Andronaco Industries), each an established manufacturer of corrosion-resistant pump solutions.

A sealless magnetic drive pump uses a magnetic coupling to transmit torque from the motor to the impeller without a mechanical shaft seal. This eliminates seal-related leaks, fugitive emissions, and seal maintenance, making magnetic drive pumps well suited for hazardous and corrosive chemical service.

ANSIMAG pumps feature molded ETFE wetted components that can handle a wide range of corrosives and solvents at temperatures up to 250°F (121°C). Chemical compatibility should be confirmed for each specific application.

Air-operated double diaphragm pumps are used for chemical transfer, slurry handling, abrasive service, and applications requiring a sealless pump that can handle variable viscosities and run dry without damage.

Magnetic drive pumps are centrifugal pumps best suited for continuous, lower-viscosity chemical transfer where leak-free operation and energy efficiency are priorities. AODD pumps are positive displacement pumps better suited for variable-viscosity fluids, slurries, abrasives, and applications requiring intermittent or continuous duty with the ability to run dry.

Yes. Cortrol provides technical guidance to help match pump type, material, and configuration with your chemical, temperature, flow, pressure, and installation requirements.
