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

YYYYY = Factory Installed Options
Model designations may include one or more of the
following characters in alphabetical order:
AG = alcohol-gasoline Compatible
(100% ethanol or methanol capable) Note: Standard
models 0% to 15% ethanol or methanol capable)
F = Floating suction adapter (1 1/2” NPT female adapter)
K = Intake filter screen (IFS, factory installed to PMA)
*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
33 = 1/3 hp Fixed Speed
75 = 3/4 hp Fixed 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
specific fixed 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

Notes:
1. Above models are UL and cUL listed for compatibility with fuel mixtures containing:
STP (Non-AG) = up to 15% Ethanol or Methanol with Gasoline, and 20% MTBE, 20% ETBE, or 17% TAME with Gasoline.
STPAG (Alcohol-Gasoline) = up to 100% Ethanol or Methanol with Gasoline, and 20% MTBE, 20% ETBE,
or 17% TAME with Gasoline.
2. All models are supplied with Standard Check Valve unless factory option “R” or “W” is specified.
3. All above models require Single Phase, 208-230 VAC, 60 Hertz 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.
