The Hypro 4101 Roller Pump is manufactured by Hypro and is an essential component in pesticide spray rigs. The purpose of Hypro roller pumps is to deliver a pressurized spray of a variety of fluids for pest control and lawn care applications.The Hypro 4101 Roller Pump is used for agricultural and industrial spraying and transfer of a variety of fluids, including insecticides, herbicides, emulsives, aromatic solvents, liquid fertilizers and many other liquids.

This pump features a max flow of 7 gpm. and a max pressure of 150 psi. A speed of 2600 rpm. and a 5/8" solid stainless steel shaft. It doesn't need the assitance of check valves which significantly reduces friction and torque so it performs efficiently.

Tools Needed

To use the Hypro 4101 Roller Pump you will need to install it onto a pesticide spraying rig. For this, you will need a base plate (sold separately), two Lovejoy couplets and a pressure regulator. You will also need a strainer to catch any debris.

How to Use

• Step 1: Following system installation instructions that come with the Hypro 4101 Roller Pump service manual, install the roller pump to your pesticide spraying rig system. The Pump hooks up to the gas engine via 2 Lovejoy couplets and you will need to mount it on a base plate which will hold it onto the frame then configure plumbing.
• Step 2: Prime the pump by making sure all connections are tight and do not leak air. Also, make sure the strainer line is free of debris. If the pump does not self-prime, disconnect the suction hose, fill it with water and reconnect it to the liquid source. A squirt of oil into the pump ports will help to prime by sealing clearances.
• Step 3: After every application, flush the pump with a cleaning solution that will neutralize the liquid pump then flush it with a 50-50 solution of car antifreeze and water to prevent corrosion. Turn the shaft several times to drawl the protective liquid through the pump to coat the entire inner surface and then drain the pump and plug the ports to keep air out.

Where to Use

The Hypro 4101 Roller Pump can be used on power sprayers and pesticide spraying rigs and is essentially the heart of the sprayer. It can be used as part of a spraying rig on industrial sites, residential areas or agricultural settings.

When to Use

Use the Hypro 4101 Roller Pump when you need to replace an older Roller Pump that has lost pressure on your power sprayer or spraying rig. This is a great pump for applications requiring high volume, but not necessarily high pressure.

Safety Information

The Hypro 4101 Roller Pump is safe to install and operate when done so by following the service manual instructions. Use the proper PPE (gloves, long-sleeved clothing) when operating and maintaining the roller pump.

Special Considerations

Never pump corrosive or abrasive liquids as these will cause rapid wear or deterioration of body, rotor, shaft, and seals in the pump. The pump should be used only with liquids compatible with pump component materials. Never exceed maximum specified rpm and pressure. Never run the pump dry. Failure to follow this warning will void the product warranty.
