Introduction

Simple Replacements

The nano pump is designed for easy repair. The most frequent repairs such as
plunger seal change and filter frit change can be done with the nano pump in
place in the system stack. These repairs are described in "Simple Repair
Procedures" on page 108.
When opening capillary or tube fittings solvents may leak out. Please observe

appropriate safety procedures (for example, goggles, safety gloves and protective
clothing) as described in the material handling and safety data sheet supplied by the

Some repairs may require exchange of defective internal parts. Exchange of
these parts requires removing the nano pump from the stack, removing the

input socket prevents that the pump cover is taken off when line power is still
connected.
