Mounting

The pump can be installed horizontally or vertically with the shaft at the top. If thenpump is installed on the tank or above the oil level, the distance between the pump inlet and the oil level should not exceed 1 metre. When installing a HYDAC pump always ensure that the fluid remains in the pump during stoppages.

Suction pipe

If the pump is installed above the oil level, particular attention must be paid to the suction pressure. The cross-section of the suction pipe must be equal to or larger than the cross-section of the pump port. The suction pressure must be kept within the values specified. Minimum suction pressure: 0.8 bar abs. Maximum suction pressure: 2.0 bar abs. – When installing a HYDAC pump always ensure that the fluid remains in the pump during stoppages.

Drive

Use a flexible coupling whenever possible. There must not be any radial or axial forces on the pump shaft. The maximum misalignment of the shafts is 0.2 mm and the angular deviation must be less than 0.2°.
