Intended Use
Hydraulic pumps convert mechanical energy (torque and speed) into hydraulic energy (pressure, oil flow).
PVM pumps are designed for industrial applications.
The pumps fulfill the explosion requirements of the Directive 2014/34/EU and UKEX SI 2016 No. 1107 for
the category shown on the name plate within the limiting conditions mentioned within this user manual
or product catalog/ technical information.
PVM pumps have an identifying name plate. The name plate provides essential information and
specification for correct and safe use.
This identifying plate has to be maintained so that the data can be clearly read; consequently, a periodic
cleaning of the plate is required. If the nameplate or other labels need to be removed for maintenance or
service, they need to be reinstalled before the pump is being recommissioned.
