Description Kamoer Replacement Pump Head for FX-STP Replacement 6-roller head assembly for the Kamoer FX-STP Dosing Pump. Over time it is common for the rollers to start to wear and cause additional friction, which can slow the pumps motor and require additional electricity to operate. We recommend changing the pump head assembly every 9000 hours, or as needed. What’s Included? 1x FX-STP Dosing Pump Head
