Where our pumps run
Founded as SolarJack
Jim & Sandy Allen
Founders, SolarJack
Families, ranchers, and farmers in remote places struggled with the same basic challenge: reliable water. Off the grid, that meant diesel generators, windmills, or hauling by hand. It was a burden, financially and physically.
The Allens believed there had to be a better way. With that conviction they launched what was then known as SolarJack.
At the time, solar energy was hardly mainstream. It was considered experimental, unreliable, or just too expensive. But Jim and Sandy were determined.
Their vision was simple but powerful: harness the sun’s energy to create water systems that just worked: no fuel, no noise, no constant maintenance. Over time, their small company grew into a trusted name in the solar pumping industry.
Every step taken on a job site, not in a boardroom.
Jim & Sandy Allen begin building solar pumps for off-grid ranches in southeastern Arizona.
The submersible diaphragm pump that customers still call us about. Many of these earliest SDS pumps are still running.
The SolarJack operation is incorporated as Sun Pumps, Inc. same shop, same focus on rural off-grid water.
A working network of installers across the western U.S. who install, service, and stand behind every system.
Annual training in Safford. Dealers, installers, and NRCS technical service providers around one bench.
Expanded the lineup with helical rotor (HR) and helical surface (HS) pumps for deeper-well and high-head applications.
Hoisington families take the reins" Body: "Garrett & Tate Hoisington, and their families, continue the legacy. Same building. Same phone number. Same promise.
Across 7 countries. Pumps from 1985 still pumping. Parts in stock for 15+ year-old systems.
Today · the next chapter
Garrett & Jenna Hoisington and Tate & Tiffinny Hoisington stepped in to continue what Jim and Sandy started with the same perspective the Allens had: livestock to water, equipment to fix, and problems to solve with your hands.
Co-Owners · Engineering & Operations
Garrett runs the engineering side of the shop, the application sizing calls, the dealer training, the room where pumps get torn down and rebuilt. Jenna keeps the business running, the team taken care of, and the families behind every order remembered by name.
Co-Owners · Strategy & Customer
Tate handles strategy and customer relationships, the long phone calls with ranchers in their tenth year of owning a Sun Pump, the dealer conversations that turn into 20-year partnerships. Tiffinny supports across the business as needed, raising the family alongside the shop.
“We grew up in a small agriculture town, where solving problems with your hands wasn’t an option. It was a way of life. Between raising livestock, repairing equipment, and finding creative solutions for everyday challenges, we learned early on how much difference a reliable water system makes.”

Our purpose
Sustainable solar water pumping and power solutions for the people and places that need them most. For ranchers keeping cattle watered in remote pastures. For farmers irrigating a field. For families powering an off-grid home.
We help families stay on the land they love, ranchers care for their herds, and communities thrive even when the grid doesn’t reach that far. Reliability matters. Service matters. Trust is earned over time, not sold in a box.
Equipment can't fail in the places we serve. Every system is engineered to outlast the warranty paperwork.
A real person picks up the phone. Parts in stock for pumps we built 15+ years ago.
Solar in, water out. No fuel, no noise, no carbon, for forty years and counting.
Helping families stay on the land they love. The work is the point.
Looking ahead
Technology changes, but the needs of rural families, farmers, and ranchers remain the same: water when and where it’s needed. We continue to refine our designs, explore new possibilities, and stand behind every product we make.
What started nearly 40 years ago as a bold idea has become a lifeline for countless people around the world. Yet the heart of Sun Pumps remains unchanged: we build products that last, we stand behind our work, and we help people live and work where they belong. Even when the grid doesn’t go that far.
