Free silicone tubing included.
KZ25 pump head is designed for high flow rates. Its robust construction from high-quality materials makes it ideal for industrial applications, with stainless steel rollers, PPS compression block and PC housing. The head is stackable on compatible drives.
The transparent housing allows to check the running state of the pump, while the compression block is self-lubricating to reduce tubing wear.
Cartridge and base can be separated to easily load the tubing.
Each pump head has 3 rollers, allowing it to reach up to 6000 mL/min at 600 rpm.
Tip: The Long Shaft version is for connecting the pump head to a Longer drive directly, while the Short Shaft version is for adding stacked pump heads to a drive with one mounted head.
Silicone tubing 24# (6.4 mm ID x 11.2 mm OD) and 35# (7.9 mm ID x 12.7 mm OD) are included with each pump head!
