Piston Seal Wash System

Vanquish Pumps (VH-P10-A-02) Operating Manual
To keep the pistons wet and rinse the piston seals, the pump has an
active piston seal wash system (seal wash system). Piston seal washing
prolongs the lifetime of the pistons and seals by preventing
crystallization and particle deposits on the piston surfaces and seals,
which may otherwise damage the pistons and seals.
The picture shows the flow path through the seal wash system.
