The MSD41 Piston Pump is manufactured by Maruyama and is a 3/4 direct drive piston pump that delivers a consistent and reliable application. The MSD41 piston pump is an essential component used in our custom spraying rigs. It is constructed of chemical-resistant aluminum with modular design to ensure a simple and worry-free repair and maintenance.

The pump comes equipped with a regulator and can pump out 8 gallons a minute at 570 pounds of pressure. It also features a Uniflow design to ensure that fluid only moves in one direction, which makes it so there is low pulsation and vibration while the MSD41 is being operated. If your piston pump has been compromised, this replacement Maruyama MSD41 piston pump will get your spraying rig back working the way that it should.

Tools Needed

There will be tools necessary to install the Maruyama MSD41 piston pump onto your spraying rig. Refer to the instructions that come with the part to see what you need.

How to Use

• Step 1: Following the manufacturer instructions, remove the old piston pump from your spraying rig and replace it with the Maruyama MSD41 Piston Pump. Tighten to secure.
• Step 2: Fill the crankcase of the MSD41 piston pump with lubricating oil up to the center level of the gauge and feed a few drops of oil into the 3 holes of the crankcase. You will then need to attach the strainer for the hose coupling and insert the suction hose and overflow hose into the chemical tank.
• Step 3: Make sure the pressure regulator is set to START and then close the valve before starting the engine. When you're ready to spray, regulate the pressure to your desired output and open the valves.
• Step 4: When you are done spraying, close the valve and turn the pressure regulator knob back to the START position.

Where to Use

Special Considerations

The Maruyama MSD41 Piston Pump is a specialized part of our custom pesticide spray rigs. Refer to the pump's manual for detailed operating procedures and maintenance information.

The MSD41 Piston Pump requires an engine to power it as it will not function on its own. A 3.6 hp (GX160 gas engine) is required.
