Ordering Guide
A typical turbine model designation has up to five components to define the pump being supplied as follows:
STP XXXXX Y - 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).
B
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)
•
W* = Model W check valve (1.10 bar relief/0.89 bar
reset for PPM4000)
M = MagShell® (flow enhancing, expanded PMA shell)
R* = Model R check valve (1.65 bar relief/1.52 bar
reset for PLLD)
Z = Pump motor horsepower rating
•
•
A
VS2** = 2 Hp variable speed
VS4 = 4 Hp variable speed
A = Model length (see table)
•
•
•
VL1 = STP variable length range #1
•
Riser pipe length is expressed as two numeric
characters that indicate the total length of the riser in
inches. Riser pipes are available from 178 mm to
1524 mm in 25.4 mm increments (additional charge
for risers 787 mm or longer).
VL2 = STP variable length range #2
VL3 = STP variable length range #3
B = Riser pipe length (diagram above)
