40RPS series pumps are designed for low flow applications of 48 GPM or under. They can be self-installed or placed using a local installer. At 100 feet of head the 40RPS20 will pump 52 GPM! 

This RPS pump uses a hearty 3 Wire Single Phase 2HP Motor and 3.85″ diameter pump end. The Outlet includes a built in check valve, most people add on an additional external check valve as well. The most efficient brushless motors mean no replacement of carbon brushes and years of smooth, reliable performance. Impellers are made of a composite material resistant to abrasion and chemical damage. Encapsulated winding for superior short protection. The entire body is made of corrosion resistant 304 stainless steel, and compliant to all drinking water standards. Includes a starter box matched to the pump HP with starting capacitor.

Using a pressure tank or pressure system? You'll need to add the depth of your well with the PSI in feet of head to get your "Total Head" number for sizing. 

10 PSI = 23 feet of head 

20 PSI = 46 feet of head 

30 PSI = 70 feet of head 

40 PSI = 90 feet of head 

50 PSI = 115 feet of head 

60 PSI = 140 feet of head

Example: 50 foot (well depth) + 90 feet of head (from a 40 PSI pressure tank) = 140 feet of total head. If your total head number exceeds this pumps ability range, size up to get a similar flow with higher head ability!

RPS Laser Welded Construction

No Plastic Parts

Other pump companies use a mix of plastic and sub-par metal parts to construct their pumps, often those parts crack or break within a few months. RPS only uses anti-rust stainless steel.

Water Tight Motor Housing

Laser welding the top and bottom of the motor housing results in a superior watertight seal that protects your pump. No leaks!

Our Pledges to You

  1. Be a company our Grandfathers would have trusted. The trend of ‘outsourcing’ customer support after the sale is a trend we wholeheartedly oppose. We are an American, family run company and our USA engineers support you before and after the sale.
  2. No sales pressure. Ever. Nobody in the company is paid on commission. We think this is important. Their role is to make sure they find the right pump for you and your well. If we don’t have a livestock solar pump that will suit your needs, we will help you find a solution elsewhere. Our job is to help get you water.
  3. Reliable Water. All manufactured products have occasional issues and we can’t claim to be perfect. However, we are proud of a near perfect track record in getting our customers water. This starts with selling a pump sized for your usage with our Water Assurance Plan and promptly addressing warranty issues to get you up and pumping again quickly.
  4. Give you the power! When you control your ability to pump water out of the ground, whether that is in the field or at home, it makes you more resilient and independent. We are here to help educate you about solar water pumping for livestock and our systems over the phone, with our manual - so you can install yourself. Take control of your water supply today.
  5. Fight for the American rancher. RPS is a David & Goliath story of a small American company fighting against a big European pump corporation that cares more about profits then the longevity of their pumps and the sky-high price for ranchers. Thanks to all our customers for the support of small business vs. foreign corporations trying to profit off some of the hardest working people in our great nation.

Taylor Hostetler (Cleveland, US)
3/4 hp 18gpm pump amd motor.

Fast delivery. Great customer service. Quality parts. Looks to be a usa rps pump but motor looks to be outsourced. Could ve wrong. Much much nicer quality then cheap store bought pump. Will definitely use them again if i need to do so

Ricky Dye (Charleston, US)
1/2 hp replace

Replaced my 40 year old Dayton with an RPS model after referral from another customer. Best move I could have made. Easy install, great construction on the pump, and trouble free thus far. Could not be happier.

The check valve seems to leak a little.

It pumps all right but seems to leak slowly back through the check valve .

Jeff F (Copper Center, US)

Vito Adragna (Gilroy, US)
3hp 35rps30

Worked as described, with great customer service. Will buy again in the future.

mark landa (Midlothian, US)
Great, so far !

I am east coast but could not find this motor anywhere around here at a decent price. Found these guys and ordered, product arrived in 6 business days and seemed to be a good quality built unit. We installed and unit is running as should. Now I just hope it will hold up for many years. I like the 3 wire system as from what I heard they are supposed to last much longer.

Elpidio Gonzalez (Helotes, US)
