Print Brochure:


Legacy is introducing the next wave in high-pressure pumps, the Legacy HD pump. This heavy-duty high-pressure pump is the outcome of 2 1/2
years of research and development, resulting in a number of upgrades over previous pump models. Premium, long-life components and new design
features make the Legacy HD pump a standout among other high-pressure pumps. Tests prove it will hold up better in rugged working conditions.

We believe the Legacy HD Pump is the strongest, most durable pump in the market. We’ve tested the pump in
extreme conditions and are confident in it’s strength and performance. We ran the pump dry in separate tests
for 24 hours, and the pump showed no sign of wear.
We challenge you to try the new Legacy HD Pump. Run the pump dry. Run it in bypass. Take it apart and look
how well it holds up. The Legacy HD holds up in these extreme conditions. Imagine how it will perform with
everyday regular use!
