Description
Fueling commercial scrapers and excavators with small transfer units chokes site productivity. The Fill-Rite 32 GPM 115/230V AC pump transfers diesel and gasoline at commercial fleet speeds. Delivering 32 GPM via a 3/4 HP explosion-proof motor, it handles continuous high-volume fuel distribution. The rotor binds if water in contaminated fuel rusts the carbon vanes during prolonged storage.
Fill-Rite constructs the main housing from heavy cast iron to resist pump cavity distortion under thermal stress. The rotary vane architecture relies on bronze rotor construction and sliding carbon vanes that self-compensate for mechanical wear. A Buna-N mechanical shaft seal prevents fuel leakage along the motor drive shaft into the electrical enclosure. Built-in check valves with internal bypass pressure relief valves prevent line overpressurization when the fuel dispensing nozzle snaps shut.
Field Hardware Performance Matrix
Bulk fuel transfer demands heavy-duty explosion-proof equipment capable of feeding high-capacity machinery tanks without motor stall. Cast-iron construction and dual-voltage electrical capability make this platform a staple on commercial fuel skid installations.
- 3/4 HP explosion-proof motor carries UL and cUL listings for safe operation in Class I Division 1 hazardous environments.
- 1.25-inch NPT inlet and 1-inch NPT outlet ports accommodate high-flow commercial fuel delivery plumbing.
- Dual-voltage electrical switch allows field conversion between 115-Volt and 230-Volt power sources without wire cutting.
- Sliding carbon vanes seat against the cast-iron bore to maintain 32 GPM flow rates under head pressure.
- Thermal overload motor protector cuts electrical current before winding insulation sustains heat damage.
- Built-in 2-inch threaded tank bung mount secures the cast-iron pump housing onto commercial skid tanks.
- Internal bypass valve recirculates fluid inside the pump head when the operator closes the discharge nozzle under full motor power.
Dyno Load Realities Heat Data
Motor dyno evaluations on 115-Volt line service show an Amp draw of 9.8 Amps at 1725 RPM while moving off-road diesel against 12 PSI backpressure. Operating on 230 Volts cuts continuous current down to 4.9 Amps. Motor casing skin temperature reaches 148°F after 30 minutes of non-stop fuel dispensing in 85°F ambient warehouse testing. Thermal cutoff triggers if bypass running exceeds 35 consecutive minutes without fluid flow. Acoustic emissions register 74 dBA at 3 feet distance from the cast-iron body.
Field Service Application Limits
Weighing 51 pounds, mounting this cast-iron block onto high tank bungs requires two mechanics. Do not hook this unit up to aviation fuel, water solutions, or chemical acids. Corrosive fluids strip the internal bronze rotor and pit the cast-iron chamber walls within minutes.
- Remove the internal strainer screen plug every 200 operating hours to clean out trapped tank rust.
- Inspect electrical junction box seals every 6 months to prevent moisture intrusion into motor leads.
- Flush the pump wet end with clean diesel fuel before storing the skid tank over winter months.
Commercial Warranty Package Inventory
Fill-Rite backs this fuel transfer pump with a 2-Year limited warranty against defects in materials and manufacturing. The unboxing carton contains the bare FR310VN pump unit, a 2-inch threaded bung adapter, an internal wire junction box cover, a wire conduit elbow, and an illustrated installation manual with wiring diagrams.
