Technical Information
PVPV, PVPVM • Pump Side Modules for Variable Displacement Pumps
Introduction
PVPV, PVPVM application
Danfoss is able to supply pump side modules type PVPV and PVPVM for systems with variable pumps.
The modules offer the following advantages:
P- and T-connection ports: 1" [1 5/16 UN]
•
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
•

Flow characteristics for PVPV/PVPVM
Flow from PVB (without pressure compensator) left and right of PVPVM respectively.
Under certain circumstances systems with large pump flows may occasionally generate pressure peaks.
For advice on systems of this nature, please contact the Danfoss Sales Organisation.

Technical Information
Introduction
PVPV, PVPVM • Pump Side Modules for Variable Displacement Pumps
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.

PVPVM dimensions
MA, LS : G¼ [9/16 - 18 UNF]
Stay bolt set, PVAS for PVPVM
In PVG 32 valve groups fitted with PVPV use standard PVAS, 157B8001 → 8010.
For pump pressures over 320 bar [4641 psi], use stay bolt set 157B8041 → 8050.
