Worcester UPM4L Pump 68W ErP1 8737605865 – Refurbished
SKU: WRCT-PMP-5865-R
Inconsistent water flow or reduced heating distribution in a Worcester Greenstar 4000 Series boiler can often be traced to a worn high-efficiency circulation pump. The Worcester UPM4L Pump, 68W, ErP1 compliant (Part No. 8737605865) is the direct replacement that restores optimal heating distribution and system efficiency.
This is a professionally refurbished unit, tested to ensure reliability and performance — a cost-effective alternative to a new OEM part for modern high-efficiency boilers.
