<strong>Fishman</strong> NoFlex <strong>Linear</strong> <strong>Drive</strong> <strong>System</strong><br />
<strong>Fishman</strong>’s patented NoFlex <br />
<strong>Linear</strong> <strong>Drive</strong> <strong>System</strong> makes the LDS9000,<br />
hands down, the most repeatable dispenser in the world<br />
Pressure loss is enemy number one to<br />
hydraulic positive displacement<br />
dispensers. Pressure loss<br />
occurs when:<br />
A leak in the hydraulic line<br />
will cause pressure loss<br />
The <strong>Linear</strong> <strong>Drive</strong> <strong>System</strong> design assures<br />
Zero Pressure Loss. Here are some reasons why:<br />
Sturdy precision machined<br />
screw and precision motor<br />
assure zero backlash during<br />
operation which eliminates any<br />
chance of pressure loss.<br />
Weak “Reverse<br />
Motion” guide wire<br />
creates lags and<br />
backlash resulting in<br />
pressure loss<br />
The precision motor is<br />
directly engaged with<br />
the screw eliminating lags<br />
and backlash and<br />
preventing any chance of<br />
pressure loss<br />
Loose fit between the<br />
drive rod and the<br />
piston results in<br />
slippage causing<br />
pressure loss<br />
Loose fit between<br />
the piston and the<br />
stabilizer will<br />
cause pressure<br />
loss, resulting in<br />
poor performance<br />
Piston slides North-<br />
South and rocks<br />
East-West,<br />
movement causes<br />
pressure loss<br />
Using a .007" interference fit<br />
pneumatic piston for AirFree <br />
dispensing allows fluid blowby,<br />
causing pressure loss<br />
O-ring failure will<br />
cause pressure loss<br />
Piston does not<br />
easily detach<br />
from stabilizer<br />
when the<br />
syringe is empty<br />
Using a thin wall pneumatic<br />
piston for AirFree dispensing can<br />
result in the side wall collapsing,<br />
causing pressure loss<br />
Thin-walled pneumatic piston<br />
can flex under pressure<br />
causing pressure loss and<br />
resulting in poor<br />
performance<br />

<strong>Fishman</strong> Piston Comparison<br />
Why Air Pistons cannot be used for AirFree <br />
Pressure loss destroys dispensing repeatability<br />
dispensing<br />
.007 Interference fit does<br />
not seal the chamber,<br />
thin wall flexes under<br />
pressure, allowing fluid<br />
to flow by—creating a<br />
pressure loss<br />
PosiLok <br />
industrial<br />
thread locks the piston<br />
to the drive rod<br />
guaranteeing no<br />
slippage during<br />
dispensing—no<br />
pressure loss<br />
.015 Interference<br />
fit completely<br />
seals the<br />
chamber—no<br />
pressure loss<br />
No interlocking<br />
connection between<br />
the piston and the<br />
drive rod. Piston<br />
slips during the<br />
dispense, creating<br />
pressure loss<br />
The Competition<br />
Thin wall flexes under<br />
pressure, creating<br />
pressure loss<br />
Thick, maximum-strength wall for high-pressure<br />
dispensing—no flexing/no pressure loss<br />
