ADVANCED PROTECTION
SUBMERSIBLE TURBINE PUMPS
Available as a factory installed option on STPAG and IST® biofuel compatible
submersible turbine pumps, Advanced Protection defends STPs from accelerated
corrosion caused by the acetic byproduct of microbial activity.
HIGHLIGHTS
• Powder-coated and E-coated finishes protect exterior cast surfaces from
accelerated corrosion.
• Stainless steel fasteners, riser, variable length column pipe and coupler
protect against corrosion and provide long service life.
ORDER INFORMATION
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 (IST® for variable speed models)
• XXXXX = Factory installed options (Model designations may include one or
more of the following characters in alphabetical order.)
• AP = Advanced protection with coated exterior cast surfaces, stainless
steel fasteners and piping, alcohol-gasoline compatible)
• F = Floating suction adapter (1½" NPT female adapter)
• H = High pressure deadhead output (150 and 200 models only)
• K = Intake filter screen (IFS, factory installed to PMA)
• M = MagShell® (flow enhancing, expanded PMA shell)
• *R = Model R check valve (1.65 bar relief/1.52 bar reset for PLLD)
• Y = Pump motor horsepower rating
• 75B = 3/4 hp fixed speed, single phase
• 75C = 3/4 hp fixed speed, three phase
• 150B = 1 1/2 hp fixed speed, single phase
• 150C = 1 1/2 hp fixed speed, three phase
• 200B = 2 hp fixed speed, single phase
• 200C = 2 hp fixed speed, three phase
• VS2 = 2 hp variable speed**
• VS4 = 4 hp variable speed***
• A = Model length
• VL1 = Variable length range #1
• VL2 = Variable length range #2
• VL3 = Variable length range #3
• B = Riser pipe length
• 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).
Notes:
*If not otherwise specified, all STP models are supplied with standard model check valve (2.76 bar relief/2.41
bar reset for MLD, TS-LS300, and TS-LS500).
**Implied on IST® models unless VS4 is specified.
*** IST® models only.
