Solar Power System Pumps (Panel Wash, RO/DI, Glycol & Site Utilities)
Utility-scale PV and C&I rooftops run on clean water, reliable distribution, and low-touch service. We outfit RO/DI skids for spot-free panel washing, inline/multistage for distribution and pressure boosting, self-priming for field transfer, and submersibles for sumps. For chemistry (anti-scale, detergents) we pair sealless mag-drive transfer with digital/peristaltic metering. Brands: Grundfos, Goulds, Griswold, Gorman-Rupp, BJM, Finish Thompson, Iwaki, LMI, Neptune, Emec, Walchem, Flux, J.L. Wingert, Wilden, Yamada, ARO.
Best-Fit Pumps for Solar Power Sites
| Service | Best Pump Type | Recommended Brands | Why It’s Best |
|---|---|---|---|
| Spot-free panel wash water (RO/DI feed) | Multistage centrifugal (VFD) | Grundfos CR | High head, compact footprint, quiet pressure control to RO array |
| RO permeate distribution / boost | Vertical inline / End-suction centrifugal | Grundfos TPE; Goulds; Griswold | Efficient, serviceable pressure and flow control across long runs |
| Anti-scale / detergent dosing | Digital diaphragm / Peristaltic metering | LMI PD/TD & KML/KBL; Neptune; Emec; Walchem (control) | Accurate ppm with validation hardware; hose option for off-gassing chemistries |
| Chemical transfer (acid/caustic/antiscalant) | Mag-drive sealless centrifugal (PP/PVDF/ETFE) | Finish Thompson DB/UC; Iwaki MX/MD | Leak-free containment; broad compatibility and simple maintenance |
| Field water transfer / truck fill | Self-priming centrifugal | Gorman-Rupp | Fast prime, above-grade clean-out; rugged for dusty sites |
| Equipment pads / drains / sumps | Submersible solids-handling | BJM | Reliable pit dewatering with guide-rail service |
| Portable wash carts / remote zones | AODD (bolted) | Wilden; Yamada; ARO | Self-priming, run-dry tolerant, simple field maintenance |
| Drum/IBC handling for RO chemicals | Drum/IBC pump + injection hardware | Flux; J.L. Wingert (columns, quills) | Ergonomic loading with calibrated injection and sampling |
Note: We bias low-TOC wetted materials for RO/DI and protect wash quality with antiscalant control, proper back-pressure, and clean injection.

How We Engineer Solar Duty
- Water quality first: RO/DI with proper antiscalant and back-pressure controls.
- Quiet pressure: VFD multistage/inline near BEP to reduce energy and noise.
- Field serviceability: self-primers and guide-rail submersibles for fast O&M.
- Chem containment: sealless mag-drive transfer for corrosives and detergents.
- Validated dosing: calibration columns, anti-siphon, back-pressure, and quills.

Solar Pump FAQs
Why multistage for RO feed on wash systems?
Multistage pumps supply the high, stable head RO membranes require while staying compact and energy-efficient under VFD control.
How do you keep dosing accurate in the field?
Digital/peristaltic metering with back-pressure, anti-siphon, calibration columns, and quills maintains ppm even with long runs and elevation changes.
When is self-priming better than submersible?
Use self-priming for above-grade clean-out and quick service; submersible wins for compact sumps or where noise/footprint is constrained.
