Recommended Plumbing
Pump Inlet must be plumbed using 25mm (1.0 inch) diameter hose and/or thin walled tubing from the fluid
supply to the pump inlet.
A restriction in the inlet plumbing is allowed as long as the flow diameter is not less than 17mm (0.75 inch) and
does not exceed 25mm (1.0 inch) in length.
Deviations from the Recommended Plumbing must meet the Inlet Requirements and be approved by
EMP Engineering. Please contact EMP customer service for installation review.
Mounting Screws
Mounting screws used should be M8 x 1.25 screws (qty=4). These must have a minimum thread engagement
of 0.50 inch (12.7 mm) and be tightened to a torque of 15 ft-lb (20N-m).
CAUTION: THE MOUNTING HOLES ARE TAPPED TO A DEPTH OF 0.59 INCHES (15MM). BE AWARE OF
THE BRACKET THICKNESS WHEN SELECTING THE FASTENER LENGTH TO ENSURE THAT THE FASTENER
WILL NOT BOTTOM OUT IN THE PUMP HOUSING.
Hose Clamps
When making the inlet and outlet hose connections to the pump it is strongly recommended to use SAE20CT
worm drive type hose clamps. Torque worm drive clamps to 45 in-lbs per SAE J1508. Spring type clamps are
not recommended.
