Compatible Epson Printer Models

This ink pump fits Epson WorkForce WF-4725, WF-4734, WF-4740, WF-4270 and EcoTank EC-4030 printers. It replaces the original printhead pump assembly used during ink charging and cleaning cycles. The part is supplied new and ready for installation.

Restores Ink Flow Function

A working pump draws ink from the tanks through the printhead, preventing air bubbles and nozzle clogging. Without it the printer cannot prime the system or run maintenance routines, so print jobs stop or produce blank pages. This replacement returns the printer to normal operation.

Questions about this item

Will the ink pump for the WF-4725 need periodic cleaning or full replacement after a certain print volume?

The pump is a service part installed during printhead maintenance; it is replaced when ink flow issues appear rather than on a fixed schedule.

What is the first limit reached during continuous printing with the WF-4740 pump installed?

Sustained use is typically limited by the printer's own duty cycle and ink reservoir capacity, not by the pump itself.
