SPEC SHEET 203-001

Section:    203

Effective:  October 2005

Replaces:  December 1999

Design

Blackmers STX3 is made from 316 stainless steel with

external ball bearings, non-metallic Duravanes,

Teflon

®

elastomers, and Blackmer chemical

mechanical seals. The STX3 has an adjustable relief

valve, versatile mounting bracket and is self-priming.

Application

The STX3 offers flow rates up to 250 gpm (946 lpm)

with differential pressures up to 125 psi (8.6 bar)

and maximum speed of 800 rpm. The STX3 typical

applications are solvents, chemicals, sulfates,

vegetable oils, urea and many acids.

Benefit

Blackmers STX3 offers fast fluid off-loading. A typical

off-loading of a 6,000 gallon (22,700 liter) tanker

can be unloaded as quickly as 24 minutes.

Blackmers non-metallic vanes self-compensate

for wear and allow the STX3 to run dry for short

periods of time for self-priming and blowing lines

clean, with out pump damage.

Blackmers STX3 is designed to offer easy

maintenance because the internal wear is limited

almost completely to the sliding vanes, which can

be replaced with ordinary metric hand tools.
