Procurement questions
What buyers usually ask before the first order
Final commercial and technical terms are confirmed in the quotation.
Are the parts guaranteed to fit?
Interchangeability is verified against the submitted pump model, position number and available dimensional data before the order is accepted.
What if I only have a nameplate photo?
Email the photo together with any available dimensions or service details. Engineering will confirm what can be identified and what additional information is needed.
Which certificates are supplied?
Depending on the component, the shipment can include EN 10204 3.1 MTR, PMI results, dimensional inspection and Certificate of Conformance.
Can you supply obsolete ANSI pump parts?
Yes. Reverse engineering can be reviewed when an OEM number, sample, drawing or sufficient dimensional data is available.
