Installation
• Check pump rotation. See Determining the Rotation of
Pump.
• Pump should always be mounted in a level, horizontal
position on a firm, flat surface.
• Grade 5 bolts should be used in installation. It is important
to use flat washers and lock washers.
• We recommend the use of oil resistant hose on both the
inlet and outlet sides of the pump. If using direct drive
system, always use a flexible coupling. We recommend the
use of Woods Sure Flex Couplers.
• If a muffler is used on discharge side of pump, inlet and
outlet of muffler must be at least equal to inside diameter
of pump outlet.
