Easy load pump head change the tubing easily and rapidly. Can connect pump heads together according to the usage, which
is easily to match the OEM application.
SF35 pump heads is made of PPS( polyphenylene sulde material), has great rigidity and structural performance. Have super
high temperature resistance and corrosion resistance. Especially in the anti organic solvents and other strong chemical
corrosion performance. Eectively reduce the pump head damage rate, then reduce the customer’s cost.

3.1 Single Pump Head
Firstly the coupling connected with the spindle of pump
head,according to the graphic tight the screws,then put the
pump head connect with the driver through the coupling.
3.2 Multichannel Pump Head
When multiple pump heads are connected in series, use
longer screws.
Dual heads as an example, rstly the coupling connected
with the spindle of pump head 1,tight screws M5,secondly
put the spindle nose of pump head 2 into spindle groove of
pump head 1. As shown below,connect the double heads
with the drivers.
Note:
When install the pump heads, if the pump heads split seperately,the rollers should be staggered installed.As shown below
photo.
Need to install adapter sleeve between the two pump heads’ spindle,as shown above,otherwise pump head work unnormal.
Note:
Try to pinch the screws with balanced force, which should
