STEP 4 HYDRAULIC PLUMBING
DIAGRAMS D & E show proper plumbing for Models SS675ER, SS675HR, SS675E3000ND
& SS675H3000ND. Please carefully read the Helpful Hints and Notes listed below before
beginning.
HELPFUL HINT
:
We recommend the use of minimum 1 1/2” suction hose. If the suction
hose is too small the hydraulic pump will cavitate and fail prematurely. A 3/4” pressure
hose is recommended for flows up to 25 gpm. A 1” pressure hose is recommended for
flows greater than 25 gpm. The 675 Series has a 2” suction port for high flow and tandem
applications.
NOTE
: Be careful not to over tighten NPT threads. It is very easy to crack these
types of ports when tightening fittings.
