The Shurflo 2088-554-144 is a 12V diaphragm beverage pump rated at 3.5 GPM and 45 PSI, the OEM-spec replacement pump for mobile applications where you need food-safe positive-pressure water or beverage delivery and don't have access to 115V AC. Food trucks, RVs, mobile bars, festival beverage rigs, and any setup running off a 12V battery bank.

Why 12V Over 115V

The 2088-series 12V Shurflo is the right call when AC power is unavailable, unreliable, or impractical. Generators are noisy and expensive; 12V battery banks are silent, light, and the right format for true mobile beverage operations. The 45 PSI output matches typical beverage system requirements without an additional regulator.

Application

Pairs with bag-in-box syrup, water transfer, and beverage delivery scenarios. Built-in pressure switch starts the pump on demand and shuts off at setpoint, the standard 'open-the-faucet, pump-runs' behavior. Diaphragm design is self-priming up to several feet of vertical lift.

Service Notes

OEM Shurflo replacement pumps are interchangeable across most beverage rig setups using 2088-series pumps. Confirm voltage, GPM, and PSI specs match your existing pump before swapping. Pairs with standard 1/2 inch NPT or barb fittings. Service kits and replacement diaphragms available separately for in-field repairs.
