Variable Speed (Non-AG) Submersible Turbine Pump

Specifications

Power Requirements

VS models can only be powered by a MagVFC™ controller.

• VS4 models require three phase incoming power supply to the MagVFC™ for proper operation.
• VS2 models can operate with single or three phase incoming power supply to the MagVFC™.
• Incoming power supply to the MagVFC™ can be 200-250 VAC, 50 or 60 Hz.
• MagVFC™ outputs a three phase, variable frequency signal, valid for FE Petro Variable Speed pumps only.
• MagVFC™ max. Line Draw: 20 Amps.
• VS4 max. motor Draw: 15 Amps.
• VS2 max. motor Draw: 9 Amps.

Pump Motor

• 2 hp or 4 hp, variable speed, 2-Stage centrifugal type pump motor with integral, automatic, thermal overload protection
• Max. flow: VS2 = 110 gpm, VS4 = 140 gpm
• Max. pressure: selectable operating pressure on MagVFC between 24 psi and 42 psi deadhead.
• Available with MagShell™ expanded shell which results in 45% increased flow area around motor.

Liquid compatibility

• Max. liquid viscosity: 70 SSU @ 60 °F (15 °C)
• Variable speed (Non-AG) models are UL and cUL listed for fuel mixtures containing up to 15% ethanol or methanol, and 20% MTBE, 20% ETBE, or 17% TAME with gasoline.
• Variable speed (non-AG) models can also be used with diesel fuels, fuel oils, kerosene, Avgas, and jet fuels in a non-gelled pourable state.
• All wetted elastomers are made of a high grade, fluorocarbon viton compound.

Standard Features

• Variable speed (Non-AG) models are available in variable length and fixed length options
• Check valve: 2 3/4" diameter fluorocarbon viton seal constructed on cast aluminum body and steel backing washer.
• Pressure relief valve: available in four pressure relief settings, integral to check valve. Standard model relieves at 40 psi and resets above 35 psi.
• Siphon: venturi type siphon primer supplied with every submersible. Siphon check valve and secondary siphon sold separately.
• Air eliminator: every submersible includes tank return path, with one-way check valve, to provide active air elimination
• Electrical disconnect: electrical yoke for positive contractor disconnect during service

Approvals

• All variable speed models are UL and cUL listed.
• Consult factory for other applicable approvals.

quality certification

• Franklin Fueling Systems is an ISO 9001 certified manufacturer.

Designation System

Click here to view the diagram.

A typical turbine model designation has up to five
components to define the pump being supplied as follows:

STP YYYYY A - B - C
STP = Basic Model Designation
Note: For alcohol-gasoline compatibility, variable speed, and
variable length models, refer to Intelligent submersible
turbine models.

YYYYY = Factory Installed Options
model designations may include one or more of the
following characters in alphabetical order:
F = Floating suction adapter
(1 1/2” NPT female adapter)
K = Intake filter screen (IFS, factory installed to PMA)
M = MagShell™ (flow enhancing expanded PMA shell)
*R = Model R check Valve
(24 psi relief / 22 psi reset for PLLD)
*W = Model W check Valve
(16 psi relief / 13 psi reset for PPM4000)

*Note: If not otherwise specified, all STP models are supplied
with standard model check valve (40 psi relief / 35 psi reset for
MLD and LS300).

A = Pump Motor Horsepower Rating
VS4 = 4 hp variable speed
VS2 = 2 hp variable speed

B = Model Length**
VL1 = variable length range #1
VL2 = variable length range #2
VL3 = variable length range #3

**Note: VL2 models fit 94% of all known installations. See
Variable Speed Model Number tables for specific model length
range details.

C = Riser Pipe Length
Note: Riser pipe length is expressed as two numeric characters
that indicate the total length of the riser in inches. Riser pipes are
available from 7” to 69” in one inch increments (add’l charge for
risers 31” or longer).

Ordering Information

IST - Intelligent Submersible Turbine (Variable Speed, Variable Length, AG Compatible)

1. Remove “M” from Model Number for non-MagShell™ Pump Motor Assembly.
2. All above models are UL and cUL listed for compatibility with fuel mixtures containing up to 100% ethanol or methanol with gasoline, diesel fuels, and 20% MTBE, 20% ETBE, or 17% TAME with gasoline.
3. All models are supplied with standard check valve unless factory option “R” or “W” is specified.
4. All above models can only be powered by a MagVFC™. 4 hp models require three phase incoming
power supply, 2 hp models can be supplied with single or three phase incoming power.

* Model length (B) defined as the dimension from turbine manifold bottom to pump motor inlet. ** 4” riser pipe, if supplied locally, must be 4 1/2” OD by 3/16” wall thickness tubing. *** For riser pipe lengths 31” to 69”, adder charge applies.
