MS-188
The Haskel MS-188 is a 0.33 HP air-driven pneumatic liquid pump with a 188:1 nominal pressure ratio, engineered to produce high liquid pressure from compressed air without electrical power. It can deliver up to 15,000 PSI continuous hydraulic output, making it suitable for industrial fluid handling, pressure testing, and calibration applications.
Features
Pneumatic operation eliminates risks associated with electrical heat, open flames, and sparks.
Output pressure and flow are adjustable through air supply control.
Automatic stall-to-hold feature maintains set pressure without continuous air consumption.
Compact and robust design engineered for demanding industrial environments.
Ideal for frequent start/stop cycles and automated processes.
Capable of handling a broad range of industrial liquids, depending on seal selection.
