1Safety Cautions
Warning: Please read through this user’s guide carefully before
operating the pump head.
Danger: Remove the power from the pump before mounting or
unmounting pump head to the drive.
Danger: Remove the power from pump before attempting any
maintenance or any cleaning operation is started.
Danger: Turn drive off before removing or installing tubing. Fingers or
loose clothing could get caught in drive mechanism.
Warning: Tubing breakage may result in fluid being sprayed
from pump. Please check the tubing frequently and change the
tubing in time.
Warning: Please power the pump off before installing external control
devices.
Warning: This product is not designed for, nor intended for use in patient
connected applications; including, but not limited to, medical and dental
use.
Note:
•Only use matched tubing with the pump head to ensure optimum
performance. Use of other tubing may void applicable warranties.
•Release the tubing loading levers if the drive stopped for a long
time to prevent the rollers from squeezing the tubing all the time.
•Change the squeeze section of the tubing in time to extend its
lifetime.
•When tubing breakage occurs, please use a mild detergent
solution to clean the pump head. Do not immerse nor use
excessive fluid. Please check if the rollers can still rotate smoothly.
If not, please stop the drive to prevent it from damaging the pump
head.

2Introduction
KZ25 pump head is designed to provide a simple, easy-to-use peristaltic
pump system. It accepts several different tubing sizes for a wide range of
flow rates, up to 6L/min. The housing and compression block can be
separated to load the tubing conveniently.
The pump head is compatible with GOLANDER drives with high torque
such as WT-S, WT-F, BT100S-1, BT100F-1. Mount the pump head
using the 2 screws provided. The pump head is stackable.

tubing retainers. Then put the compression block back.
4) Press the compression block and rotate the lever all the way to
the right to lock it.
5) Adjust the fastening screws to push the retainer to the right

FASTENING
SCREW
Figure 4. Fastening Screws Adjustment
Note: The fastening screw is for adjusting the gap between compression
block and tubing container to hold the tubing. It does not adjust flow rate.
To check the gap between compression block and tubing retainer, put one
end of tubing into water and pump air into tubing from the other end. There
should be no bubbles coming out from tubing on the end in water.
Otherwise, it means the gap is too small.
6.2 Pump Head Installation
1) Be sure the pump drive is turned off.
2) Mount the mounting panel on the drive.
3) Align the shaft tang of the pump head to the coupler of the drive.
4) Tighten the mounting screws to secure the pump head on the
drive. Ensure the tightness of the two tightening screws is the
same and should not be too tight in order to prevent noise due to
deformed housing.

7Warranty
The product comes with one-year labor and parts warranty. The limited
warranty does not cover any damage that is caused by improper usage
and handling.
8Regular Maintenance
1) Always check the tubing and connections to make sure there is
no leakage. Keep the pump head dry.
2) Do not use chemical solvents to clean the head.
3) As time goes on, the flow rate will slightly change. Please adjust
the drive speed or calibrate the flow rate when necessary. Change
the tubing when necessary.
4) There would be 3-5% difference among the channels for multiple-
channel pump head. For higher precision application, we
recommend only use one channel pump head on each pump.
