New Western Fisher Plow Pump Ultramount Flostat 4000 PSI Hydraulic Unit 56544 22155-1

A New Western Pump Kit # 56544.

This is the same as the Fisher 22155-1 and 9840-2. It is for the non-Fleet Flex plows. Used on the Western Midweight, Ultramount Pro Plows and the Pro Plus plows.

* If your pump has a plastic cover other the top, that is a Fleet Flex pump and it would use parts # 42345-1.

Other pumps that may or may not mount differently would be Fisher kits # 42293-1 and # 42291-1. Fisher uses this pump on the RD, HD, XBlade, MC, HD2, and HDX. Fisher also has a 2500 PSI cross over pump which is part # 22160-1 and came in kits # 9825-1 and # 9835-1.

This is a new pump. They have a 1 year warranty, but you must properly flush your cylinders and hoses before hooking this pump up and use Genuine Western / Fisher oil.
