Tips

1. Peristaltic Pump Description

a) A peristaltic pump, a type of positive displacement pump, is used for pumping a variety of fluids with specific flow rate.
b) A peristaltic pump normally consists of three components: pump drive, pump head and tubing.
c) The pump head consists of two parts, rotor and housing. And the tubing is squeezed and released between the rotor and housing to transfer the fluid.
d) When a peristaltic pump is working, the fluid flows in the tubing, so the fluid only contacts the bore of the tubing. The pump will not contaminate the fluid, and the fluid will not contaminate the pump.

e) Some factors will affect the flow rate of a peristaltic pump, such as pump speed, pump head structure, tubing size, tubing elasticity, fluid viscosity, etc. Normally, (1) the flow rate is proportional to the rotor speed, which means that peristaltic pumps are well suited for dosing. (2) the bigger ID of the tubing, the bigger flow rate. (3) the worse the fluidity of the fluid, the smaller the flow rate. (4) the bigger suction lift, the smaller the flow rate.

2. Peristaltic Pump Installation

a) Pump unpacking
Take out the pump and accessories from the shipping carton. Check the packing list to make sure all components are present.
b) Appearance check
Inspect the pump for any signs of damage occurred while in transit.
c) Set up
Place the pump at a site that is leveled/aligned. The environmental temperature and humidity should be within the specified limit (refer to pump specification for the details).
d) Electrical connection
All access ports are inspected and cleared of any debris. Connect the pump to proper power supply, and properly earthed single-phase voltage outlet. Refer to operating manual for the electrical rating. Power on the pump, the pump-on indicator or screen should display.

3. Peristaltic Pump Operation

a) Check the keys responding for its pressing well.
b) Check the screen displaying well
c) Check the tubing size suitable for the pump head (refer to pump specification)
d) Load the tubing properly. Ensure the tubing will not move or be dislocated when the pump is working, and the fluid can be transferred through the tubing.
e) Set the parameters (refer to operating manual for details)
f) Calibrate the flow rate or dispensing volume if necessary. Before the calibration procedure, ensure that the tubing is filled till the end.
i. For the pump with flow rate mode, calibrate the flow rate according to operating manual.
ii. For the pump with dispensing/dosing mode, calibrate the dispensing volume according to operating manual.
iii. For the pump only has speed control mode, calibrate the flow rate based on the linear relationship between flow rate and the pump speed.
