There are a few different types of pumps that can pair with the TRP Rosin Press. You can choose a manual hand pump or an air hydraulic or electric hydraulic pump to pair with the press. The type of pump you choose depends on how you will be using the machine. Manual pumps provide a better feel and modulation with the press, but they typically require more effort on the operators part. An air hydraulic pump delivers more modulation and speed, but requires an external air compressor.
