Case Study

Case Study Volute Pumps


Automotive Industry, UK.

Scope of work

A manufacturer of parts to the car industry delivered 2 x 30 year old pumps to our Leeds workshop. As the original manufacturer no longer existed, replacement parts were not available; therefore the work to protect the pumps against a chemically corrosive environment was required.


Corroglass 600 series.


Cast iron.

Coating system

  • Stripped pumps, rebated suction/drained flanges
  • Pre-machined all fitted areas
  • Masked all areas not requiring coating
  • Blasted internals, Sa2 1/2 to achieve profile of 50 microns
  • Lined internals with Corroglass 600 to DFT of 1.25mm
  • Removed surface dressing, dress edges
  • 100% visual inspection
  • Post machine fitted areas to original sizes
  • Externals blasted to Sa2, applied Plasmet ZF
  • Reassembled and pressure tested
  • Packed ready for dispatch and recommissioning
