How we verify a bolt-on replacement
The quotation follows a drawing-led check before you place an order.
Send the original model
Share the nameplate model and your required duty.
We check the interface
We verify flange size and orientation, foundation bolt pattern and shaft height, then send the equivalent model and outline drawing.
You confirm before quotation
You review the drawing; after confirmation, we prepare the quotation.
What you get with the quotation
Tell us the duty point (capacity, suction pressure, seal-liquid temperature) and we return, normally within one working day:
- Performance curve — capacity against suction pressure at your seal-liquid temperature — not a catalogue figure
- Dimensional outline drawing — flanges, bolt pattern, shaft height, so you can check the fit before ordering
- Material specification — wetted-part materials for your gas and liquid, with certificates on delivery
- Utility figures — seal-liquid flow and motor rating, for sizing the supply and the starter
If the drawing does not match your original, we say so and do not quote.
Confirm the drawing before you order
Send the original model and duty. We will return the equivalent selection, outline drawing and performance curve with the quotation.
