HOW TO CHANGE ROTATION DIRECTION ON THE PUMP:
Remove the 4 screws. 1
Remove the 2 flange halves 2

NOTE: Do not rotate the pump shaft before the set screw 4 is in place.
NOTE: Rotation adjustment screw 4 is always the output side of the pump.
Calculation of suction hose:
Flow
Size suction hose
0-65
1 ½” / 38 mm
0-120 l/min
2” / 50 mm
120-160 l/min
2 ½” / 63 mm
160-250 l/min
3” / 76 mm
This is valid when tank is place above the pump.
When tank is placed beside or under the pump the max flow/ hose size should be reduced.
LS Drainage:
Connect at least
10 mm (½ ") hose
direct to tank to
prevent back
pressure.
Pressure limit. Factory set at ~100bar
Stand-by Pressure control. Factory set at 30 Bar
Connect all hoses to the pump.
The pump should get oil through the
drainage hose. Make sure the pump has oil
using the bleed screw.
Open the bleed screw (don’t unscrew
completely) and check if oil comes out.
If no oil comes, remove the screw
completely and manually fill the pump
with oil. Mount the screw and tighten.
Start up the hydraulic system on low speed
Start an operation to evacuate any
remaining air in the tubing and pump.
Bleed the LS line.
