SPECIFICATIONS
Power Requirements
• ⅓ and ¾ hp fixed speed models require single-phase,
208-230 VAC, 60 Hz incoming power.
• Check valve: 2¾" diameter fluorocarbon seal constructed
with cast aluminum body and steel backing washer.
• ⅓ and ¾ hp fixed speed models incorporate a starting and
running capacitor, with internal bleed resistor, rated 370 Volt,
15 microfarad.
• Pressure relief valve: available in four pressure relief settings,
integral to check valve. Standard model relieves at 40 psi
and resets above 35 psi.
• SPGC-220 single-phase Guardian Series™ Controllers and
STP-CBS single-phase control boxes are available for ⅓ and
¾ hp pump control.
• Syphon: venturi-type syphon primer supplied with every
submersible. Syphon check valve and secondary syphon
sold separately.
• ⅓ hp max. motor draw: 4 Amps.
• ¾ hp max. motor draw: 7 Amps.
• Air eliminator: every submersible includes a tank return path
with one-way check valve to provide active air elimination.
Liquid Compatibility
• Max. liquid viscosity: 70 SSU at 60 °F (15 °C).
• Electrical disconnect: electrical yoke for positive contractor
disconnect during service.
• Standard STP models are UL and cUL listed for fuel
mixtures containing up to 10% ethanol with gasoline, and
20% MTBE, 20% ETBE or 17% TAME with gasoline.
Pump Motor
• ⅓ and ¾ Hp fixed speed, 3450 rpm, two-stage
centrifugal type pump motor with integral, automatic
thermal overload protection.
• STPAG/STPAP (AG compatible) models are UL listed for fuel
mixtures containing diesel fuel with up to 20% Biodiesel,
100% Biodiesel, up to 85% ethanol with gasoline, and 20%
MTBE, 20% ETBE or 17% TAME with gasoline.
• ⅓ Hp models have a max. pressure of 27 psi.
• ¾ Hp models have a max. pressure of 30 psi.
• ⅓ and ¾ hp fixed speed models can also be used with
diesel fuels, fuel oils, kerosene, Avgas, and jet fuels in a
non-gelled pourable state.
Approvals
• cULus listed.
• Consult factory for applicable approvals.
• All wetted elastomers are made of a high grade,
fluorocarbon compound.
