What we make
Balance discs, drums and rotating parts
MSE makes the rotating parts of a pump to drawing in Germiston, east of Johannesburg: balance discs and balance drums, throwers and oil throwers, thrust collars and thrust rings, impeller nuts, locknuts and washers.
Last updated:
We turn these rotating parts on CNC and conventional lathes, grind where the drawing calls for it, and make them in the grade on your drawing.

Questions buyers ask
Who can make a balance disc or balance drum to drawing in South Africa?
MSE (Mechanical Spares & Engineering) in Germiston, Gauteng, makes balance discs and balance drums to the customer’s drawing and material. Send the drawing number and revision, the material and the quantity to orders@mse.engineer.
Can you make a special nut to a sample?
Yes. MSE makes nuts to a sample when there is no drawing, and has made piston-rod nuts and other special nuts this way. Impeller nuts and locknuts are made to drawing.
Do you make impellers?
No. MSE does not make impellers. We machine impellers that you supply, from a single operation to full machining. See machining your castings.
