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:

IST YYYYY A - B - C

IST = Basic Model Designation
Note: All IST models include the options of alcohol-gasoline compatibility, variable speed, and variable length as part of the base model.

YYYYY = Factory Installed Options
IST model designations may include one or more of the following characters in alphabetical order:

F = Floating suction adapter (1 1/2” 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)

*Note: if not otherwise specified, all IST models are supplied with standard model check valve (40 psi relief/35 psi reset for MLD and LS300)

A = Pump Motor Horsepower Rating**
VS4 = 4 hp variable speed

**Note: If not otherwise specified, 2 hp variable speed is implied.

B = Model Length
1 = 2 hp variable length range 59” – 87”
2 = 2 hp variable length range 90” – 151”
3 = 2 hp variable length range 122” – 213”
VL1 = 4 hp variable length range 64” – 92”
VL2 = 4 hp variable length range 95” – 156”
VL3 = 4 hp variable length range 127” – 218”

Note: IST-2 and ISTVS4-VL2 models fit 94% of all known installations.

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

Fixed Length Submersible Turbines Pumps

1. Remove “M” from Model Number for non-MagShell Pump Motor Assembly.
2. 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.
3. All models are supplied with Standard Check Valve unless factory option “R” or “W” is specified.
4. 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.
Model Length (B) can be a minimum of 37” to a maximum of 211”
Adder charge to List if Model Length (B) is 133” to 180” (charge is for boards to protect STP shipment)
