Maximum pressure
The pump must be protected against excessive pressure, by means of a pressure restrictor valve. Setting
of that pressure restrictor valve effected by using a pressure gauge for control.
Speed --- Sense of rotation
According to the size of the type concerned, the minimum service speed is approx. 500 r.p.m. The nominal
speed is 1400 r.p.m. All performance data stated in the leaflet are based on these ratings. In that leaflet, you
will find also the maximum speeds of the individual types. Normal sense of rotation is clockwise, and marked
by an arrow. When the unit is taken into operation, the correct sense of rotation of the electrical motor should
be checked by turning it ”ON” for a short period of time (maximum 5 seconds) before the line is filled with
fluid for the first time.
Clutch
The diameter tolerance of the shaft end is j6. The diameter tolerance of the clutch hub should be in accordan-
ce to H7.
Start---up operation
It will be usefull to fill the pump and the suction with pressure fluid by manual rotation, before putting the
motor into operation. After that, the pump should be set to ”supply” condition, by turning the motor ”ON”.
In doing so, watch the fluid level in the tank until bleeding of the system is positively finished, in order to make
sure that the fluid level does not decrease to an amount less than the minimum suction limit. After the first
start---up operation (in depressurized condition), the system should be turned ”OFF” again, in order to allow
separation of air dissolved in the oil. Operation of the pump in pressurized condition is acceptable only if
the pressure fluid does not contain any bubbles.
Maintenance
General
The gear pump is lubricated by the oil and, therefore, does not require any maintenance. Care and service
work are restricted to keeping the hydraulic oil perfectly clean, to checking the oil level and the temperature,
and to cleaning of the filters. In this context we recommend that our detailed instructions for operation and
service of pipe filters should be complied with. In order to preclude any corosion, the pump should be filled
with oil if it is kept on stock for a substantial period of time (more than one year).
Malfunctions and remedies
Even if all instructions and notes of advice are strictly complied with, a malfunction may occur in some or
other case. The remarks listed here---below are to help you to identify and eliminate the fault, taking into
account the symptoms actually detected.
