Pump selection looks simple from the outside — pick something big enough and get it on site. In practice, getting it right involves a handful of technical factors that are easy to overlook until they cause a problem halfway through a project.
Flow rate and head aren’t the same conversation
A pump rated for high flow won’t necessarily handle the head pressure your site needs, and vice versa. Site elevation, pipe run length, and discharge distance all affect what “the right pump” actually looks like — which is why matching equipment to a spec sheet alone doesn’t always get it right.
Diesel or electric — it depends on the site, not preference
Power source is often decided by circumstance rather than choice. Remote sites without grid power lean diesel; sites with existing electrical infrastructure and noise or emissions restrictions often favour electric. Run time, fuel logistics, and refuelling access all factor into which makes sense for a given job.
Backup matters as much as the primary unit
A single pump with no contingency is a risk most projects can’t afford, particularly where downtime has a real cost. Standby units, monitoring, and support access all reduce that risk — and it’s worth factoring in before equipment goes to site, not after something goes wrong.
Experience shortens the guesswork
None of this is complicated in isolation, but getting all of it right, quickly, under project pressure, is where experience counts. It’s the accumulated pattern-matching from having done it before — recognising a site’s constraints and knowing what’s worked in similar conditions.
That’s the value we try to bring at AMG — not just supplying pumps, but helping get the selection right the first time.
