Description
Maintain continuous domestic water pressure throughout rural homes, cabins, and outbuildings. The Star Water Systems Systems 1/2HP Cast iron jet pump system delivers dependable pressurized water. A 0.5-horsepower motor couples to a 20-gallon horizontal pressure tank. The shallow-well jet configuration cannot lift water from depths exceeding 25 feet.
Cast-iron forms the rugged jet pump casing, dampening vibration and resisting mechanical distortion under pressure. A heavy-gauge steel pressure tank features an internal butyl diaphragm that separates water from air charges. The single-phase 115/230-volt motor uses a continuous-duty capacitor for reliable starts. Precision brass injector nozzles channel water velocity into the pump volute. A pre-set pressure switch controls pump cycling.
Jet Pump Tank Architecture
Rural property owners supply pressurized water to outbuildings without separate tank plumbing. Pre-assembled tank groupings reduce field plumbing labor and save floor space.
- Dual-voltage 0.5-horsepower motor operates on standard 115-volt or 230-volt wiring
- Shallow-well jet pump produces 8.5 GPM to supply multiple water fixtures
- Integrated 20-gallon steel tank maintains line pressure to cut motor starts
- Heavy cast-iron pump body dampens operational noise and resists physical damage
- Factory pre-set 30/50 PSI pressure switch activates pump operation automatically
- Internal butyl tank diaphragm keeps air charges separate from fresh water
- Standard 1-inch NPT suction and discharge ports simplify field pipe connections
Pump Station Dyno Telemetry
Bench testing demonstrates the motor draws 6.8 Amps on 115-volt power during continuous 40 PSI line pressurization. Water output delivers 7.8 GPM from a 15-foot suction depth. Motor frame temperature reaches 136°F after 2 continuous operating hours. Sound meters record 66 dBA at 2 meters distance. Tank pre-charge air pressure holds at 28 PSI.
Operational Boundaries Field Realities
You bolt this compact pump skid onto concrete basement slabs with standard anchors. The integrated tank design fits inside tight utility crawlspaces. Do not run this jet pump without priming the casing with water first. Operating the internal diffuser dry melts the thermoplastic injector within two minutes.
- Check tank air pre-charge pressure with a tire gauge once every 6 months
- Drain the pump casing and tank before leaving unheated cabins in winter
- Clean the brass jet injector nozzle if water delivery volume begins falling
Commercial Warranty Manifest Terms
Star Water Systems provides a 1-Year limited warranty covering pump and tank components. The shipping box includes the 0.5-horsepower jet pump, 20-gallon pre-charged tank, 30/50 pressure switch, and complete plumbing installation manual.
