P2 = Intermittent operating pressure (1/3 of working time)
P3 = Peak pressure

To use the diagram shown above, select the pump displacement on the basis of flow required.
Then draw a vertical line to intersect the line representing the pump series.
Now you can select the group on the basis of required application pressure.
Example: 38 cm3/rev 2.5PB 38 220 bar (3140 psi)

If required application pressure is more than 220 bar, use a 3 PB

"B" SERIES
Features
GENERAL
SALAMI gear pumps and motors are available in seven series giving options of displacements from 1.1 cm3/rev to
98 cm3/rev(from 0.06 cu.in./rev to 6.03 cu.in./rev).
All pumps are available as multiple units either of the same or different series.
With all sizes of pumps and motors there are options of shafts, flanges and ports as for European, German and
American standards.
SALAMI gear pumps and motors offer:

High volumetric efficiency by innovative design and accurate control of machining tolerances.
Axial compensation achieved by the use of floating bushes that allow high volumetric efficiency throughout the
working pressure range.
DU bearings ensure high pressure capability.
12 teeth integral gear and shaft.
Extruded alluminum body.
Die cast alluminum cover and flange - cast iron rear.
Double shafts seals in all pump series except Group 1.
Nitrile seals as standard and viton seals in high temperature applications.
All pumps and motors are hydraulic tested after assembly to ensure the high standard performance required by
SALAMI'S engineering.
WORKING CONDITIONS
THE VALUES OF PRESSURE ARE ABSOLUTE
- Pump inlet pressure 0,7 to 2,5 bar

10 to 36 psi
- Return pipe line continuos pressure for motors MAX 2,5 bar - 36 psi
- Return pipe line intermit. pressure for motors MAX 6 bar for 15 sec - 85 psi
- Return pipe line peak pressure for motors MAX 15 bar - 215 psi
- Minimum operating fluid viscosity 12 mm2 / sec
- Max starting viscosity 800 mm2 / sec
- Suggested fluid viscosity range 17 - 65 mm2 / sec
- Fluid operating temperature range -15 to +85 °C
- Hydraulic fluid mineral oil
Important:
in case of assembling of pumps without shaft seals (eg. B2 - B3....), you have to keep the value of
min. suction pressure ( 0.7 bar (abs)) in the vane between pump and coupling too.
Lower pressure can lead to suction of oil through the front flange (seat of the shaft without seal);
this can damage seriously the pump.

Features "B" SERIES
DRIVE SHAFT
Radial and axial loads on the shafts must be avoided since they reduce the life of the unit.
Pumps driven by power take - off on engines must always be connected by placing an "Oldham" coupling or coupling
having convex toothed hub.
This is to ensure that inevitable misalignment during assembly is reduced to minimum.
PUMP ROTATION DIRECTION VIEWED AT THE DRIVE SHAFT
Outlet Inlet Inlet Outlet
Anti - clockwise rotation Clockwise rotation Reversible rotation
HYDRAULIC PIPE LINE
To ensure favorable suction conditions it is important to keep pressure drop in suction pipe line to a minimum value
(see WORKING CONDITIONS).
To calculte hydraulic pipe line size, the designer can use; as an approximate guide, the following fluid speed figures:
From 1 to 2 m/sec on suction pipe line From 3.28 to 6.36 ft/sec on suction pipe line
From 6 to 10 m/sec on pressure pipe line From 19.7 to 32.8 ft/sec on pressure pipe line
The lowest fluid speed values in pipe lines is recommended when the operating temperature range is high and/or for continuos
duty.
The highest value is recommended when the temperature difference is low and/or for intermittent duty.
When tandem pumps are supplied by 2 different reservoirs with 2 different fluids it is necessary to specify "AS" version.
In case of reversible motor allowance must be made to ensure the motor is not drained, through the case drain, when stationary.

Rotation changing instructions for pumps GROUP 1

Before starting, be sure that the pump is
cleaned externally as well as the working
area to avoid that particles dangerous for BOLT
pump working can find their way into the
pump. COVER
Pump represented is an anti-clockwise
rotation pump.
Picture "A"
1 - Loosen and fully unscrew the clamp DRIVING GEAR FLANGE
bolts.
2 - Lay the pump on the working area in
order to have the mounting flange
turned upside. Picture "A"
3 - Coat the shaft extension with grease to BODY
avoid damaging the shaft seal.
4 - Remove the flange and lay it on the
working area;
verify that the seal is correctly located
in the body seat.
Picture "B"
1 - Mark the position of the bushing relative Picture "B"
to the body.
2 - Remove the bushing and the driving BUSHING
gear taking care to avoid driven gear
axial shifts.
Picture "C"
1 - Draw out the driven gear from its housing, DRIVEN GEAR
taking care to avoid rear cover axial
shifts. Picture "C"
2 - Re-locate the driven gear in the position
previously occupied by the driven gear.
Picture "D"
1 - Re-locate the driving gear in the position
Picture "E" Picture "D"
1 - Replace the bushing taking care that:
- marks are located as on the picture
- surface containing the seal is visible
- seal and its protection are correctly
located
Picture "F"
1 - Clean body and mounting flange refaced Pict. "E"
surfaces.
2 - Verify that the two plugs are located in
the body.
3 - Refit the front flange on the body.
You can find the oppropriate rotation
mounting flange codes on this catalogue.
4 - Replace the clamp bolts and tighten
crosswise evenly to a torque of 24 - 25 Pict. "F"
Nm for 1PB, 1.5PB and 1.6PB.
5 - Check that the shaft rotates freely.
6 - Mark on the plate the new direction of
rotation.
IMPORTANT:
to reverse rotation in pump 1PB, 1.5PB,
1.6PB you need to change the front
flange. For these pumps there is one For 1PB, 1.5PB and 1.6PB see picture "F" point 3

The 2PB pumps can be easily transformed into front pump in the multiple units. All drive shafts
are pre-arranged and have a splined end according DIN 5482. The first unit must always be the
same size or bigger than following units. The features and performances are the same of the
corresponding single units: only in the case of simultaneous operating you have to verify that the
inlet torque is lower than the max. transmissible by the drive shaft.
