Oil Lubrication Pump Unit PB...
1-3008-US
Multiline unit for total-loss oil lubrication systems
on low and high-pressure compressors
General remarks
The PB oil lubrication pump unit is a multiline oil pump unit for
the lubrication of low and high-pressure compressors.
It consists of a modular piston pump with horizontal eccentric
shafts, 1 to 8 adjustable pump elements per shaft and pump
housing as well as a drop regulator for each pump element. A
laterally installed set of gears with electric motor provides for an
optimum drive speed.
The pump’s main application is the total-loss oil lubrication of
cylinders and packings on piston compressors.
Every mineral, synthetic and ecofriendly oil can be delivered with
the oil lubrication pump unit.
Oil Lubrication Pump PB..
Advantages
Exact metering of lubricant for economy or full lubrication
Adjustable delivery rates at each outlet port (for economy or
full lubrication)
Different operating pressures and delivery rates (thanks to the
use of different pump elements) are possible on one pump
Applications on compressors for:
Easy to change the number of outlet ports at later date
delivery and storage of natural gas
Max. continuous operating pressures of up to 350 bars per
outlet port
compression of combustible and process gases
cold storage of liquefied gases
extraction of biogas in clarification plants
production of compressed air
recovery of flare gas
desulphurization of waste gases
PB oil lubrication pump units are outfitted with 1-3 pump
housings to suit the application and with 1 to a maximum of
8 pump elements per respective housing, or they can be
expanded at later date
On the suction side PB oil lubrication pump units come with
an integrated visual drop regulator and ball check valve for
each outlet port
The electrical functions and filling level can be monitored with
an SP/SFE 30/5 pulse generator
Reservoir version to suit the customer’s wishes (incl. add-ons
like heating, filling-level switch, etc.)

How the pump works
(See Figs. 1 and 2)
When the oil reservoir is filled, the oil in the pump housing (1) is
simultaneously filled via an oil supply hole between the pump
housing (1) and oil reservoir (2) so that the eccentric shaft (3)
rests in the oil bath. Even when the oil level in the oil reservoir (2)
drops, this oil bath is maintained in the pump housing (1).

The lubricating oil for each pump element (4) is delivered from
the oil reservoir (2) through the common intake tube (5) (1 intake
tube per pump housing), the drop regulator (6) and the respective
connecting holes.
The underpressure produced by the pump and the stroke of the
delivery piston (8) draws oil out of the oil reservoir (2) into the
upper part of the drop regulator (6). From there the oil is routed
through a drop section down to the intake hole in the pump
element (4).
A drop is tripped with each revolution of the eccentric shaft (3)
and/or with each suction stroke of the piston. As a result, the
functioning of every pump element (4) can be constantly
checked by way of the sight glass (7) on the drop regulator (6).

Fig. 1 Design of the PB pump
How the pump element works
(See Figs. 1 and 2)
The pressure stroke of the delivery piston (8) is force-actuated,
and the suction stroke is returned by spring force (9). In the
suction stroke position (as drawn) the cross hole of the control
piston (10) is closed.
When the pressure stroke begins, the delivery piston (8) closes
the intake hole (11). The lubricant drawn into cavity A is pressed
against the spring-loaded control piston (10), the latter moving to
the right as a result. That opens the cross hole in the control
piston (10). The lubricant makes its way under pressure through
the lengthwise and cross hole of the control piston (10) into
cavity B and from there via the ring duct and check valve (12) to
the outlet port.
The pressure stroke is followed by the suction stroke of the
delivery piston (8).
When the delivery piston (8) is moved, the control piston (10) is
also returned by spring force (9) to its initial position.
Fig. 2 Design of a PB pump element
Underpressure is produced in cavity A by the suction stroke of
the delivery piston (8).
When the intake hole opens, the lubricant flows into cavity A due
to the underpressure.
The pump element (4) is prepared for the next delivery stroke.
The delivery rate of the pump element (4) is determined by the
stroke of the control piston (10) and can be adjusted with the
setting sleeve (WAF 14) (13).

Versions
The PB pump consists of 1 to 3 pump housings, each with a
maximum of 8 pump elements. If fewer than 8 outlet ports per
housing are required, blank flanges are installed that can be
replaced at any time with a pump element. If a pulse generator
(model SP/SFE 30/5) is used to monitor the reservoir’s filling
level, the maximum number of customarily possible outlet ports
for the pump unit is reduced by one port, since this port is
needed by the pulse generator to monitor the reservoir’s filling
level. The oil delivered is returned to the reservoir in this case.

The outlet port monitored by a pulse generator can, however,
also be used a normal pressure port up to the maximum pump
pressure (or as a reserve outlet port).

Adjustment of the delivery rates
(See Figs. 2 and 5)
Delivery rate [%]
Clockwise turning reduces the delivery rate to as much as
approx. 30 %
(Minimum = 1 groove visible on pump element).
Counterclockwise turning increases the delivery rate by a
maximum of 100 %
(Maximum = 3 grooves visible on pump element).

Electric motor drive with gears
Please note!
The following delivery rate
figures are based on a mains
frequency of 50 Hz. When the
mains frequency is 60 Hz, the
delivery rates are increased by
20 %. The figures refer to
standard VEM motors. If other
makes are used, deviations
have to be expected.
