• Air eliminator: every submersible includes a tank return path with one-way check valve to provide active air elimination.
• Electrical disconnect: electrical yoke for positive contractor disconnect during service.

Pump Motor

• 2 Hp or 4 Hp, variable speed, two-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™ which results in 45% increased flow area around motor.

Approvals

• cULus listed.
• Consult factory for applicable approvals.

Power Requirements

• Variable speed pumps can only be controlled by a MagVFC™ variable frequency controller:
• VS2 models can operate with single- or three-phase incoming power supply to the MagVFC™.
• VS4 models require three-phase incoming power supply to the MagVFC™ for proper operation.
• 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.
• VS2 max. motor draw: 9 Amps.
• MagVFC™ max. line draw: 20 Amps.

Liquid Compatibility

• Max. liquid viscosity: 70 SSU at 60 °F (15 °C).
• STP variable speed models are UL and cUL listed for fuel mixtures containing up to 10% ethanol, and 20% MTBE, 20% ETBE or 17% TAME with gasoline.
• IST variable speed models are UL and cUL 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.
• All variable speed (non-AG) models can also be used withdiesel fuels, fuel oils, kerosene, Avgas and jet fuels in a non-gelled pourable state.
• All wetted elastomers are made of a high grade, fluorocarbon compound.

Quality Certification

• Franklin Fueling Systems is an ISO 9001Certified Manufacturer.

Ordering Guide

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

XXX YYYYY Z – A – B

• XXX = Basic Model Designation
  • STP = These standard variable speed and variable length models are capable of up to 10% ethanol with gasoline
  • IST** = These variable speed and variable length models include alcohol-gasoline compatibility (up to 85% ethanol, up to 20% biodiesel, or 100% biodiesel).
• YYYYY = Factory Installed Options
  • Model designations may include one or more of the following characters in alphabetical order:
  • F = Floating suction adapter (1½” 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)
• Z = Pump Motor Horsepower Rating
  • VS2** = 2 Hp variable speed
  • VS4 = 4 Hp variable speed
• A = Model Length (see table below)
  • VL1 = STP variable length range #1
  • VL2 = STP variable length range #2
  • VL3 = STP variable length range #3
• B = Riser Pipe Length (see diagram above)
  • 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 1″ increments (additional charge for risers 31″ or longer).

• *If not otherwise specified, all models are supplied with standard model check valve (40 psi relief /35 psi reset for MLD, TS-LS300, and TS-LS500).
• **If not otherwise specified, 2 Hp variable speed pump motor horsepower rating is implied for IST models.

Variable Speed Submersible Turbine Pumps

Variable speed, variable length.

Variable Speed Intelligent Submersible Turbine Pumps

Variable speed, variable length, and AG compatible.

• 1. Remove “M” from model number for non-MagShell™ pump motor assembly.
• 2. All STP models are UL and cUL listed for compatibility with fuel mixtures containing up to 10% ethanol with gasoline, diesel fuels, and 20% MTBE, 20% ETBE or 17% TAME with gasoline.
• 3. All IST models are compatible with 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.
• 4. All models are supplied with a standard check valve unless factory option “R” or “W” is specified.
• 5. 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.
• 6. 4″ riser pipe, if supplied locally, must be 4½” OD by 3/16″ WT tubing.
• 7. For riser pipe length 31″ to 69″, additional charge applies.
• *Model length (A) defined as the dimension from turbine manifold bottom to pump motor inlet.

Variable Speed Conversion Kits

With variable speed conversion kits you can achieve higher, consistent flow rates, in turn boosting your profits, while eliminating the wear and tear hydraulic hammer can cause. Installation is easy with a variable speed pump motor assembly, MagVFC™ variable frequency controller and four-wire contractor’s plug. All-in-one variable speed kits are compatible with both FE Petro™ brand 4″ submersible turbine pumps, as well as other competitive systems. The MagVFC™ works with the existing system to increase flow as more fueling points go live, delivering the flow you need as you need it. Your customers will know the difference between sites that provide steady flow and faster fueling during peak business hours and those sites that don’t.

• Note: Kits include variable speed pump motor assembly, MagVFC™ variable frequency controller, four-wire contractor’s plug and installation instructions.
