Self-priming diaphragm pump with 12v or 24v DC electric motor. Flow rates from 4-8 litres/min (1-2.1 US gallons/min) |
Self-priming diaphragm pump with 12v or 24v DC electric motor. Flow rates from 4-8 litres/min (1-2.1 US gallons/min), pressure switch control or with a bypass, or both, capable of pressures up to 6.5bar (95psi) |
Flojet's G56 Series pumps are designed for water boosting for filtration systems, supply carbonators, non-carbonated dispensing valves, carts, coffee machines, hand sinks, ice machines and FCB equipment.
Supplies up to 4gpm (15lpm). If pumping over 1.7gpm (6.4lpm), a pulsation dampener or accumulator tank should be utilized to reduce pulsation, due to momentary shifts in flow requirements. (See Flojet's K56 series Water Booster Systems)
|
The Model G57C is designed to be the ultimate in performance and reliability. Our robust design combines innovative features and relentless testing to offer a pump that has a long, trouble free service life. The pump incorporates all the great features and
benefits you expect with Flojet products — and now it’s fitted with Kalrez®.
The uniquely designed shuttle valve check valves, and its high performance capabilities have
been combined to accomplish the ultimate in compact air operated double diaphragm pump
technology. The Model G57C Pump can supply up to 5 GPM (18.9 /min.).
|
Flojet's K56 Series Water Booster Systems are designed for supplying consistent water pressure to beverage dispensers, coffee machines, water filtration systems, carbonators & ice machines. Supplies up to 4 gpm (15 lpm). For use when water requirement is over 1.7 gpm (6.4 lpm).

The Flojet 2840 Series Booster Systems are designed to provide a constant water pressure of 0 to 40 psi (0.7 to 2.7 bar) and a maximum flow rate of 4.5 gpm at 10 psi (0.7 bar). The pump is fully automatic, with built in inlet strainer, pressure switch and check valve, and supplies smooth flow from tricke to full flow. Typical uses include applications where available water pressure is very low, and fluctuates widely. Easy installation requires only that the water lines be connected, and the power cord plugged in. |
The R4400 DC VSD provides pulse free constant pressure operation on any DC voltage from 10-29 volts. Operation from no flow to maximum flow is system controlled, eliminating unwanted pump cycling and the need for an accumulator tank. The system provides reduced amp draw and quite operation when less than maximum flow is required. Standard features include soft start to reduce splash, thermal overload, over-current and reverse polarity protection. |
