Plumbing
Pump Inlet must be plumbed using 25.4mm (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 17 mm (0.75 inch) and does not exceed
25.4 mm (1.0 inch) in length.
CAUTION: Localized high spots in the plumbing will cause
air to be trapped in the pump causing the pump to be air locked.
The result of air trapped in the pump is loss of prime and no fluid
moving resulting in water seal damage or potential system
component damage.
CAUTION: EMP warranty does not cover seal damage due to low lubrication.
Improper installation with localized high spots
Deviations from the recommended plumbing must meet the inlet requirements specified in the installation
manual.
Hose Clamps
When making the inlet and outlet hose connections to the pump it is 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.
