Sauer-Danfoss is now able to supply pump side modules type PVPV and PVPVM for systems with variable pumps. The new modules offer the following advantages:

• 1" [1 5/16 in] P- and T-connection ports

• Lower pressure drop

• PVPVM enables the use of LS-pumps with flows up to 230 l/min [61 US gal/min]

• Relief of pressure peaks with PVLP 63

When ordering PVPV fitted with PVLP 63, please state the sales- and code No. in space 0 in the order form. Also, always state the PVLP 63 opening pressure in space 0 .

(See example)

PVPVM To order PVG 32 fitted with PVPVM, use standard order form DKMH.PZ.570.D8.02 520L0515 and for the SAE versions DKMH.PZ.570.B7.22 520L0354.

When ordering PVPVM fitted with PVLP 63, please state the sales- and code No. in space b in the order form.

Also, always state the PVLP 63 opening pressure in space 0 . (see example page 7)

Flow characteristics

FLOW CHARACTERISTICS

FOR PVPV/PVPVM

Flow from PVB (without pressure compensator) left and rigth of PVPVM respectively.

(For flow characteristics on PVPV, see catalogue DKMH.PK.570.C2.02 520L0344 )

Note that under certain circumstances systems with large pump flows may occasionally generate pressure peaks.

For advice on systems of this nature, please contact the Sauer-Danfoss Sales Organisation

Set pressure difference between pump pressure and

LS signal = 10 bar

[145 psi]

Set pressure difference between pump pressure and

LS signal = 15 bar

[218 psi]

The oil flow depends on the pressure difference between pump pressure and LS-signal.

Normally, the pressure difference can be set on the LS-pump control.
