Metering Pump Actuator

SC/BQ pneumatic actuators, SC/BQo and SC/Vo oleopneumatic actuators are used for metering pump applications. Thanks to their desing, they find ideal application in power plants, refineries, pipe steel works and on board of vessels. The range of products includes double acting units and are available in different sizes.

An oil tank permits to have the cylinder always full of oil, also when the piston is at the stem retracted position. Connections to the cylinder are set in order to avoid air forming into the cylinder.
