In Austin, Texas, Mike needed stable water pressure boosting and clean water delivery for his stainless storage tank and beverage system. His requirements were clear: a food grade diaphragm pump suitable for potable water transfer, quiet automatic operation, and reliable performance under low inlet pressure from a water tank supply.
He chose the Flowatt 24VDC 100W food grade solar diaphragm water pump . Built for food-contact liquid transfer, it delivers up to about 7L/min flow and 0.8 MPa pressure, with roughly 1.5 m self-priming capacity—ideal for moving water from tank to outlet in everyday beverage dispensing and drinking-water setups.
How the 24V Food Grade Diaphragm Pump Work?
This Flowatt 24VDC 100W food grade solar diaphragm water pump runs on 24V DC power, so it can connect directly to a solar-powered water pump system.
During the day, solar panels generate electricity that passes through a solar charge controller (or a storage system with DC output) to deliver stable 24V power to the pump. When sunlight is low or at night, a 24V battery bank can keep the diaphragm pump running—so water continues to move from the storage tank to the outlet without interruption.
With a rated power of about 100W, the setup stays relatively lightweight: a modest 24V solar panel array plus a compact battery is usually enough for intermittent potable water transfer and beverage dispensing.
For users like Mike who want clean water delivery with less grid dependence, solar direct power + battery backup is a flexible, energy-efficient way to run a food grade diaphragm pump.
Mike’s Solar Panel Setup for the 100W Diaphragm Pump
For Mike’s Flowatt 24VDC 100W food grade diaphragm pump, a practical solar array starts at about 150–200W.
Because the pump draws up to 100W, sizing panels at roughly 1.5–2× the pump power helps cover real-world losses, cloudy periods, and battery charging.
Suggested setups (24V system):
- Light / intermittent use: about 150–200W solar panels
- More stable daily supply: about 200–300W solar panels
Common example: 2 × 100W or 2 × 150W solar panels wired for 24V, plus a solar charge controller and 24V battery
With this range, the solar-powered water pump can run from PV by day and use battery backup when sunlight is low—keeping potable water transfer steady from tank to outlet.
Performance After Installation
After installation, Mike noticed more stable pressure boosting in daily use. Because this is a food grade diaphragm pump, it can be used for potable water / drinking water transfer—not just general boosting.
It effectively raises water pressure from the storage tank to the outlet, runs quietly, starts and stops automatically, and delivers more consistent flow for safer, easier everyday water supply.
Other Application Scenarios
Beyond Mike’s potable water pressure boosting and beverage transfer setup, this Flowatt 24VDC 100W food grade diaphragm pump also fits many clean-water and food-contact applications: food trucks and mobile catering, RV fresh water systems, café and beverage liquid transfer, small food-processing ingredient handling and cleaning loops, and solar-powered off-grid potable water setups.
Wherever drinking water or food-grade liquid transfer is required, a food grade diaphragm pump is the safer choice over a standard pump.
