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If the drawing does not match your original, we say so and do not quote.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.
