Maintenance Overview
General guidelines for the periodic replacement of the ‘wear parts’ are indicated in the table
below, according to the amount of use: intensive, regular, or occasional. This schedule should
be regarded as a guide; changes in performance, or visible leaks, give an indication that a part
should be changed.
Component
Intensive
(168 h/week)
Regular
(40 h/week)
Occasional
(10 h/week)
Piston seals 4.5 months (3000 h) 1–1.5 years (2500 h) 2 years (1000 h)
Check valves 7 months (4500 h) 1.5 years (3000 h) 3 years (1500 h)
Piston assembly 9 months (6000 h) 2–3 years (5000 h) 4 years (2000 h)
These recommendations are based on the assumption that the pump is working at half its maximum
flow rate and pressure.
To prevent injury, observe good laboratory practices when handling solvents. Know the
physical and chemical properties. Refer to the Material Safety Data Sheets for the solvents
used.
Cleaning
Keep the pumps clean for peak performance. Always turn the power off to the pumps before
cleaning. Wipe the pumps with a soft cloth dampened with a mild detergent and disinfect as
needed.
