5 PRACTICAL ADVICES ON USING PERISTALTIC PUMP
- For smaller flow rates, it is advisable to use tubing with a small diameter and high motor speed setting rather than larger tubing diameter and low speed setting. (Smaller inner tubing diameter allows finer flow rate adjustment.)
- If possible, use the peristaltic pump in clockwise direction!
In clockwise direction, the peristaltic pump runs with less friction and pressure is lesser (approx. 0.1 MPa depending on the tubing diameter). If a higher pressure is required (up to 0.2 MPa), use the counter-clockwise rotation on the pump.
- Greasing reduces friction, increases reliability and life time of the peristaltic pump: Periodically, smear a small amount of petroleum jelly or similar grease on the inner side of the transparent PVC cover of the peristaltic pump.
Do not grease the tubing holding slots on the pump head!
- In-case, if any liquid enters the pump head, disconnect the pump from mains, drain the liquid and rinse the pump head with water.
For cleaning, you can also remove the entire rotor with rollers: Unscrew the nut (M4 for PRECIFLOW, MULTIFLOW, HiFLOW and MAXIFLOW; M5 for MEGAFLOW peristaltic pumps) on the axle of the rotor and pull the rotor out by hand or with a pair of pliers. After cleaning, grease the axle and replace the rotor by pressing and rotating until the rotor engages on the motor axis.
- Clean the peristaltic pump with a damp cloth. Mild solvents such as ethanol, isopropanol, or alkanes may also be used, if the exposure time is short.
