High-pressure gear pumps and motors are quiet and efficient

Sept. 10, 2013

The AP/APM212 gear pumps and motors offer high operating pressres, volumetric and mechanical efficiency, minimal noise, reduced vibration, and low flow pulsation. The Series features 4.4 to 27.1 cm3/rev displacement; 250-bar maximum cont. pressure; –20 to 80°C fluid-temperature range, 20 to 120 mm2/sec viscosity range, and NBR+HNBR sealing materials. Advantages include:

AP/APM212 gear pumps and motors offer high operating pressures, volumetric and mechanical efficiency, minimal noise, reduced vibration, and low flow pulsation. The Series features 4.4 to 27.1 cm³/rev displacement; 250-bar maximum cont. pressure; –20° to 80°C fluid-temperature range, 20 to 120 mm²/sec viscosity range, and NBR+HNBR sealing materials. Advantages include: • Higher number of teeth and new profile results in lower pressure pulsation and less noise. • High-performance materials and innovative heat treatment increase working life. • Larger and stronger shaft increases transmitting torque.Bucher Hydraulics Inc., 847.429.0700, www.bucherhydraulics.com
