1½ Hp Fixed Speed
Submersible Turbine Pumps
Active Air Eliminator
FE Petro™ brand STPs come standard with active air elimination, which eliminates air through the highest point in the pump head at all times when the pump is running, assuring air does not pass into discharge piping.
Safety and Ease of Maintenance
FE Petro™ brand STPs include a contractor electrical disconnect, which requires loosening only one bolt, allowing motor wiring to be disconnected without venting the dangerous tank vapors into the sump when servicing FE Petro™ submersible products.
Manual Pressure Relief
As a standard FE Petro™ feature a vent screw is provided to bleed line pressure to zero when necessary. By turning this screw, product is diverted back to the tank, dropping line pressure to zero. This reduces fuel discharged into the sump manhole or dispenser pan during servicing, further protecting service technicians and the environment.
If ever required, the pump can be easily removed from the tank by unthreading three bolts. There is no need to disconnect the syphon system or to remove the leak detector from the system to service the STP.
The VL2 pump fits 94% of all known tank diameters and tank bury depth combinations. The VL1 and VL3 are available to handle installations shorter or longer than this range. The telescoping connection is a patented FE Petro feature. Pump length can be set by making one simple measurement and setting the pump length without affecting the UL listing.
Reliable Check Valve
The STP uses the proven FE Petro™ line check valve. At 2 ¾" in diameter, this valve reduces pressure loss at high flow rates resulting in faster fueling times. FE Petro™ line check valves are offered in multiple configurations to best suit your line leak application.

Use this diagram below along with the Ordering Guide to help you build your variable speed submersible turbine pump.
A typical turbine model designation has up to five components to define the pump being supplied as follows:
STP XXXXX Y - A - B
- STP = Basic Model Designation
- XXXXX = Factory Installed Options (Model designations may include one or more of the following characters in alphabetical order.)
- AG = Alcohol-gasoline compatible (up to E85, up to B20, and B100) (Note standard models up to 10% ethanol capable)
- 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)
- Y = Pump Motor Horsepower Rating
- 150 = 1½ Hp fixed speed
- A = Model Length (see table)
- VL1 = Variable length range #1
- VL2 = Variable length range #2 (Note VL2 models fit 94% of all known installations)
- VL3 = Variable length range #3
- B = Riser Pipe Length (see diagram)
- 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).
STP Horsepower Model Length Range Model Length Designation 1.5 Hp 60" - 88" VL1 91" - 152" VL2 123" - 214" VL3 1.5 Hp high pressure 61" - 89" VL1 92" - 152" VL2 124" - 215" VL3
- *If not otherwise specified, all STP models are supplied with standard model check valve (40 psi relief /35 psi reset for MLD, TS-LS300, and TS-LS500).
