About Hill Pumps
Ernest H Hill Ltd has been engineering in Sheffield since 1844, and its pumps are the reference point the rest of the market gets measured against. The MK-series hand pumps set the standard for dry-air filling with the Dry-Pac moisture system, and the EC-3000 compressor line, now succeeded by the Evo 310, brought the same philosophy to electric filling: low RPM, air cooling, 75 dB operation, and full UK design and assembly. Hill publishes complete manuals, service kits, and even a stroke-count formula for its hand pumps, a level of documentation almost nobody else in the category matches.
