Electromagnetically driven, precision-geared pumps provide smooth, accurate, pulseless flow. Torque improvements and compact size are achieved with NdFeB magnets. Control speed by using a 0 to 5 VDC input signal, a 4 to 20 mA current loop, or manual control. Drives feature thermal and overload protection.
Choose a system with a suction shoe pump head to self compensate for wear, temperature, and pressure, and to maintain high volumetric efficiency. Cavity-style pump heads deliver higher lift capability and moderate pressure capability; an internal bypass is an integral safety feature of the cavity-style pump heads.
The Suction Shoe design (Models: 74215-**) allows the pump to compensate for wear thus maintaining high volumetric efficiency.
Suction shoe service kits include: gears, suction shoe, shafts, scales, and springs.
The Cavity design (Models 74445-**) offers the benefits of higher lift capability and moderate pressure capability.
Cavity-style service kits include: gears, bushings, and seals.
