ORDERING INFORMATION
4 Hp Submersible Pump 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)
ISTAP = These variable speed and variable length models include
alcohol-gasoline compatibility (up to 85% ethanol, up to 20%
Biodiesel, or 100% Biodiesel) and Advanced Protection with
powder-coated, e-coated, and stainless steel components
(B)
RISER
LENGTH
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)

LENGTH
Z = Pump Motor Horsepower Rating
VS4 = 4 Hp variable speed
A = Model Length (see table)
VL1 = STP variable length range #1
VL2 = STP variable length range #2
VL3 = STP 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 60" in 1" increments (additional charge for
risers 31" or longer).
