The dry sump oil pump is one of your race engine s most critical parts.

Barnes oil pump pressure adjustment. The maximum allowable pressure has increased over the years from 100 to 115 psi. Tighten jam nut and re check pressure. The normal oil pressure range for most lycoming engines is between 60 to 90 pounds per square inch psi. From essential applications like sewage and wastewater to fountain pumps and revolutionary pressure sewer systems barnes pumps deliver innovative cost effective solutions supported by.

A log splitter uses a gasoline powered engine connected to a hydraulic pump. Factory preset with a 400 900 psi adjustment range. Increasing the unloading valve pressure will require increas ing the pump drive horsepower. Engineers plumbing contractors and homeowners have continued to depend on barnes pumps for reliability and durability since the brands founding in 1895.

The pressure stage of the pump provides that vital supply of lifegiving oil to all the components and surfaces which require lubrication and cooling. 20 psi per complete turn.
