The PT15 pump head is made entirely of engineering plastics, making it corrosion-resistant, high-temperature resistant, and suitable for various working environments. The pump head can be sterilized under high temperature and pressure. The PT15 uses rolling friction compression of the hose instead of sliding compression, greatly improving the hose's service life. The pump head is simple and convenient to install and remove, allowing for installation in four positions. A speed control device can be added for special requirements.
