SC/BQ - Linear Metering Pump Actuator
Compact pneumatic actuator for precise metering pump control.
Precise, repeatable performance for metering pumps.
Compact and lightweight design for easy installation.
Manual override options enhance operational flexibility.
The SC/BQ actuator series delivers precise, reliable control for metering pumps in power, refinery, and marine applications. With compact, lightweight designs and cylinder sizes from 80mm to 200mm, these actuators ensure smooth operation under demanding conditions. Pneumatic models use instrument air, while oleopneumatic variants maintain consistent oil-filled cylinders to prevent air ingress. Engineered for easy installation and maintenance, the SC/BQ features a robust construction with manual override options for added flexibility. Supporting strokes from 2mm to 100mm, they are ideal for efficient, repeatable performance in critical metering pump operations where reliability is essential.
