Mono pumps have one outlet and it supplies the front or rear screen with water. Two pumps are needed to supply both screens.
Screen Washer Pumps – Dual Pumps
Dual pumps can send the fluid in two directions. By using just one pump, washer fluid is pumped through one (or both) of the outlets to the front or rear screen.
Headlight Washer Pumps (Mono Pump)
Headlight washer pumps are used for headlight lens cleaning. They supply the headlight lens washer nozzles with a corresponding amount of water and provide the high water pressure needed for this application
Washer nozzles deliver water for cleaning front windshields, rear windshields and headlights. Some nozzles have an anti-drain valve to prevent a return flow of fluid.
Old-generation mono pumps (screen cleaning) are available as gear-type pumps (12 V or 24 V).
Anti-drain-back valves prevent any return flow of washer fluid, improving the reaction time of the washer system and fitting into the nozzle assembly.
Fluid-level switches warn you about low fluid levels.
Connectors (angles, T, I and Y) are used to join different segments of the washer hose system.
Filters protect the pump against contamination, thereby preventing damage. They are located between pump intake ports and the fluid tank.
The nozzle needle is used to adjust ball-type nozzles.
