SPECIFICATIONS
Power Requirements
• 1½ 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.
• 1½ 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 1½
Hp pump control.
• Syphon: venturi-type syphon primer supplied with every
submersible. Syphon check valve and secondary syphon sold
separately.
• Max. motor draw: 11 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
• 1½ Hp fixed speed, 3450 rpm, multi-stage centrifugal
type pump motor with integral, automatic, thermal
overload protection.
SUBMERSIBLE
PUMPING SYSTEMS
General
• 1½ Hp fixed speed models are available in variable length
and fixed length options.
• STPAP/STPAG (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.
• Standard pressure (150, two-stage) model, max.
pressure = 32 psi.
• High pressure (H150, three-stage) model, max.
pressure = 45 psi.
• 1½ 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.
• All wetted elastomers are made of a high grade,
fluorocarbon compound.
• Consult factory for applicable approvals.
