12 and 24 Volt DC Motor Driven Bronze Marine MotorPumps™
Scot Pump Marine builds many high-performance DC Motorpumps™. These innovative electronic motors provide significant energy savings. Brush life is a prime consideration. Two pole motors have a shorter brush life than four pole motors. Applications for continuous duty should use four pole motors if possible. Two pole average brush life is approximately 2000 – 4000 hours. Four pole average brush life is appreciably longer.
Permanent magnet design DC motors will run in one direction with the positive line to one lead and the opposite rotation when the leads are reversed. This reversing does not damage a permanent magnet design unless the load connected to the motor cannot operate in the reverse direction.
