Working conditions GEAR PUMPS AND MOTORS "B" SERIES QUICK GUIDE TO SELECT THE RIGHT PUMP SIZE Definition of pressures P1 = Continuos operating pressure P2 = Intermittent operating pressure (1/3 of working time) P3 = Peak pressure max. 20 s The diagram shown here below is used as a first dimensioning aid for the choice of pump group. It is based on the value of displacements (horizontal coordinates) and intermittent pressure P2 (vertical coordinates) 5.5 3.2 1.4 2.8 2.6 5.8 To use the diagram shown above, select the pump displacement on the basis of flow required. Then draw a vertical line to...

GEAR PUMPS AND MOTORS SALAMI gear pumps and motors are available in seven series giving options of displacements from 1.1 cm /rev to 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...

GEAR PUMPS AND MOTORS "B" SERIES Features 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 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...

Pls, see following example: Only for pumps 2PB and 2PZ (except triple 2PB) the identification product is marked on the top of the pump body as shown here below: A = Product short descritpion (VD8A/FDD/U4G). B = Customer part number. C = Salami part number (6235 0025 0). D = Production batch (for Salami management) Product...

GEAR PUMPS AND MOTORS "B" SERIES Rotation changing instructions for pumps GROUP 2 - 2.5 - 3 - 3.5 Before starting, be sure that the pump is cleaned externally as well as the working area to avoid that particles dangerous for pump working can find their way into the pump. Pump represented is aclockwise rotation pump. To obtain an anti_clockwise rotation read carefully the following instructions. Picture "A" Picture "A" 1 - Loosen and fully unscrew the clamp bolts. 2 - Lay the pump on the working area in order to have the mounting flange turned upside. 3 - Coat the shaft extension with grease to...
