BZ Peristaltic Pump Head

■ Lead Fluid BZ series pump head max flow rate 2100 mL/min, can be cascade multiple pump heads.
■ The ingenious pressure tube structure ensures very low transmission pulsation without increasing the roller,highest transmission accuracy and repeatability.
■ Each type of pump head corresponds to a special one size tube. It has better performance and longer service life than general pump head.
■ The shell material can be PC or PPS, the PC is transparent and easy to observe the internal operation of the pump head, PPS is better chemical res istance.
■ The roller adopts 304SS, can work long time with high speed.
■ Support two kinds of tube fixed way the whole tube and built-in t ube connector, strong applicability.
■ Classic design, stable structure, high cost performance,It can be widely used in various small and medium-sized instruments and e quipment.

Tube Life Comparison Table

For longer tube life, use thick tubes and low rotational speeds ; If a large flow rate is required, use a thick tube and high speed; Fo r higher accuracy, use thin tubes and medium to high speeds; For higher suction lift and back pressure, use thinner thick walled tubes and lower rotational speeds.
