Flojet - 4000 Series High Flow Quad Pump
High Flow Quad Pump for On-Demand Water Delivery
The FloJet 4000 Series uses a four-piston diaphragm architecture to deliver up to 4.8 gallons per minute at pressures reaching 45 psi, with integrated pressure-switch control that activates the pump only when demand exists. The chemical-resistant polypropylene head and Santoprene diaphragm with EPDM valves handle both water and viscous liquids up to 250 cP, while self-priming to 2.4 meters vertical lift eliminates the need for foot valves in most installations.
Pressure-Activated Diaphragm Pumping
Self-Priming Intake
Four-piston diaphragm assembly creates suction to draw water from sources up to 2.4 meters below pump level without external priming or foot valves
High Flow Delivery
Quad-piston design delivers flow rates up to 17 liters per minute at system pressures reaching 3.2 bar, powered by 115V AC motor drawing 1.5 amps
Automatic Pressure Switch
Factory-set pressure switch activates pump at 30 psi and cuts out at 45 psi, running motor only when system demand drops below cut-in threshold
FloJet 4000 Series Technical Data
| Voltage | 115 VAC |
| Current Draw | 1.5 amp |
| Flow Rate | 17 L/min (4.8 GPM) |
| Max Pressure | 45 psi (3.2 bar) |
| Pressure Switch | 30 psi cut-in, 45 psi cut-out |
| Self-Priming Lift | 2.4 m vertical |
| Port Connection | 3/4" hose barb |
| Pump Head Material | Polypropylene |
| Diaphragm | Santoprene |
| Valve Material | EPDM |
| Viscosity Range | Up to 250 cP |
Application Range
The FloJet 4000 Series handles potable water, non-potable water, and chemical solutions up to 250 centipoise viscosity. Santoprene diaphragm and EPDM valve materials provide compatibility with most aqueous solutions, mild acids, and alkaline fluids. The 3/4-inch hose barb ports accept standard flexible tubing for quick installation in residential water delivery, light commercial dispensing, and low-viscosity chemical transfer applications. Not rated for petroleum-based fluids or solvents that degrade polypropylene or EPDM elastomers.
