300 PSI Case Working Pressure
Rigid stucture is designed for maximum casing strength.
High Motor Efficiency
94% efficient permanent magnet motor minimizes heat input to fluid
in heat sensitive applications like chillers and refrigerant handling.
ST21 Series pumps may be operated under adverse inlet conditions
without audible or measurable cavitation.
Special inlet design provides superior fluid handling ability
with low head inlet conditions.
Every pump is fully tested to verify performance prior to shipment.
Leak Free Sealless Design
Canned Sealless motor eliminates downtime, risk, and damage associated
with mechanical seal failures. More compact and reliable than mag-drive
Versatile Motor and Controller
Integrated into the ST21 motor, a Variable Speed Controller accepts
115/230VAC or 12/24/48/100VDC power inputs and features variable
speed output (2,000 - 10,000 RPM) that can be controlled via closed
loop feedback from 4-20ma, 0-10VDC, or PWM transducers or other
Volatile Fluid Handling
The turbine impeller handles vapors up to 20% by volume, minimizing
the possibility of vapor lock.
