The Maruyama model MSD41 is a 3/4 direct drive piston pump that sets to deliver a consistent and reliable application. It uses uniflow technology which achieves 6 GPM and 570 PSI and it requires less horsepower on its peak performance and lessens the consumption of fuel. It is constructed of chemical-resistant aluminum with modular design to ensure a simple and worry-free repair and maintenance.
I use this pump on a daily basis going on two years and have had Zero issues with it. I typically average about 300-psi through it and it takes everything i throw at it. I have used other pumps that are 2 & 3 times the price of this one that require constant maintenance and the MSD41 performs just as good if not better. I would definitely recommend this pump .
