Design Features

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.

Low NPSH

Viscous friction disk impeller gently accelerates fluid to exit velocity providing superior fluid handling at very low head inlet conditions.

100% Tested

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 solutions.

Versatile Motor and Controller

Integrated into the SC31 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 control circuitry.

SC31 Options

Controllers available for 12/24/48/100 VDC or 115/230 VAC power. Controller options for manual speed control, external control via PWM, or closed-loop 0-10V or 4-20ma transducer speed control.

Pressure transducers and optional bearing and elastomer materials available upon request.

ST21 regenerative turbine pump is available for high pressure and low flow applications.
