Introduction to Pump Head
Suitable for small flow, high-precision fluid transmission in laboratories, etc.
The ratchet wheel finely adjusts the gap of the pressure pipe to adapt to pipes with different wall thicknesses
Independent loading and unloading of cards, using POM or PVDF material, strong tolerance
Character
♢ Occlusion can be adjusted slightly by ratchet wheel to fit different tubing wall thicknesses requirements.
♢ 6-rollers pump head supply more flow rate.
♢ 10-rollers reduce pulse and flow rates slightly.
♢ Skillful trigger structure, convenient to eject the cartridges (DG-1, DG-2)
♢ Rollers are made from 304 stainless steel, can resistant acid, soda and organic solvent
♢ Cartridges are made from POM or PVDF
