Industry Application

Pumps For Corrosive Hot And Viscous Chemical Duty

Chemical duty is where the wrong seal, the wrong elastomer or the wrong grade of stainless shows up fastest. The range here covers corrosive transfer, thermal oil circuits and viscous media, with seal free options where a leak is unacceptable.

What Goes Wrong On This Duty

Any leak is a safety event

Magnetic drive pumps have no shaft seal, so there is no path for the liquid to escape and no gland to maintain.

Thermal oil destroys standard pumps

Above 80 degrees a water pump is out of its range. The heat transfer line is rated for hot oil duty to 350 degrees.

Viscosity stalls the pump

Centrifugal pumps lose head as viscosity rises. Progressing cavity and gear pumps displace a fixed volume regardless.

What Buyers Ask For

  • Wetted materials matched to the chemical, not to the catalogue default
  • Seal free options for hazardous and volatile liquids
  • Pumps rated for the working temperature, stated clearly
  • Material certificates where the project requires traceability
  • Fittings and valves in the same grade as the pump

Typical Scenarios

Where The Equipment Sits

Corrosive Transfer

Moving acids, alkalis and solvents between storage and process with stainless wetted parts.

Thermal Oil Heating

Circulating heat transfer oil between heater and consumer at temperatures a water pump cannot survive.

Viscous And Solid Laden Media

Resins, pastes and slurries that stall a centrifugal impeller but move steadily through a screw pump.

How We Work

Getting The Specification Right

Liquid Data

Chemical name, concentration, temperature, viscosity, specific gravity and solids. All of it changes the answer.

Material And Seal

Casing and impeller grade, seal type or a magnetic drive, and the elastomer for the chemistry.

Documentation

Material certificates, test records and the documentation package the project demands, agreed before build.

Delivery And Spares

Works test, export packing, and spares held against the model number for the life of the installation.

Delivery

What You Get With The Order

  • Casing and impeller in cast iron, stainless steel or bronze as the liquid requires
  • Mechanical seal, gland packing or a magnetic drive with no seal at all
  • Fluid temperature ratings stated on every data sheet
  • Material certificates on request at enquiry stage
  • Stainless fittings and valves in matching grades

Answers

Chemical And Petrochemical FAQ

Which pump has no seal at all?

The magnetic drive micro pumps and the heat transfer pumps are magnetically coupled, so there is no shaft seal and no leak path.

How hot can the liquid be?

The chemical centrifugal versions carry their own temperature limits on each data sheet, and the heat transfer line is rated to 350 degrees for hot oil duty.

Can you supply material certificates?

Yes, if you ask at enquiry stage so the material is traced from the start of the build.

What about abrasive slurry?

Use the progressing cavity or rubber lobe line. Gear and centrifugal pumps wear quickly on abrasives.

Do you supply valves and fittings in the same grade?

Yes. Sanitary and industrial stainless fittings are built in the same works, in 304, 316 and 316L.
