Direction Of Rotation; Orientation; Protection From Too High Pressures - Danfoss APP W HC Series Operation Manual

Instruction | APP W HC 15 - 30 pumps
6 . Adjust respectively, verify the measure-
ment, and secure both couplings with the
right torques on the locking screws (see
coupling operation & mounting instruction) .
7 . Mount the elastic gear ring and mount the
bell housing/pump on the motor . After
mounting it must be possible to move the
elastic gear ring 3-5 mm (0 . 1 2 - 0 .2 inch)
axial "C" . The check can be done through
the inspection hole of bell housing . Secure
flange bolts with the right torque .

If alternative mounting is desired, please contact
Danfoss High Pressure Pumps .
Choose proper tolerances to ensure an easy
mounting of the elastic coupling without use of
tools .
Please take care to observe the recommended
length tolerances of the chosen coupling, as an
axial force on the pump will damage the pump .

3.4 Protection from too high pressures

The pump should be protected against too high
pressure by means of a safety valve or a pressure
relief valve .
MADE IN DENMARK The valve should be placed as close to the pump
as possible .
Danfoss A/S, 6430 Nordborg, Denmark
The opening characteristics of the valve must not
result in peak pressures higher than 132 barg
(1914 psig) .
We recommend the use of flexible soft hoses
both in the inlet and in the outlet lines .
