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If the drawing does not match your original, we say so and do not quote.
