The WOB-L piston pump features magnesium components designed to help limit the pump’s weight to 2.5 lbs. It is also quiet and offers low vibration meaning smoother running across all speed curves. A highly efficient brushless dc motor offers low power consumption for long battery life. The motor offers variable speed from 1,000 to 3,000 rpm, meaning the airflow can be steplessly varied according to application requirements. In addition, an optional closed loop controller allows motor speed to be maintained at a pre-set, constant rpm, regardless of load or voltage fluctuations. It has an open flow of 0.6 cfm, maximum pressure of 17 psi, and reaches a maximum vacuum of 22 in. Hg. The standard head configuration has 1/2 in. hosed barbed fittings, but is also available with 1/8-28 BSPT threaded ports. The pump is suitable for applications in medical, pharmaceutical, business machines, and instrumentation applications were small size and the ability to control flow rate by varying the speed is critical. It can also be custom configured to meet exact specifications or application requirements.
