This maintenance kit works for both our open direct drive and enclosed pump units.  The kit includes a new 5 micron 10″ sediment filter, 1 micron 10″ sediment filter and a 21oz bottle of pump oil. We recommend to change the filter element each year and change the oil in the pump after 500 hours of use or every other year which ever comes first.
