INLET CONDITIONSIt is essential that pumps are installed so that the pump can draw suffi cient oil under all operating conditions.1PH Series pump inlet porting is designed to facilitate full volume fi ll but the following machine designrecommendations should be followed.

Never run pumps dry - particular care should be taken to open any shut-off valves. Use large diameter pipes and fi ttings and avoid sharp bends and long lengths. Fluid velocity should not exceed 2.5 m/sec (8.0 ft/sec) calculated by:

V = 21.22Q m/sec where V = velocity (m/sec) V = 0.408Q ft/sec where V = velocity (ft/sec) Q = fl ow rate (l/min) Q = fl ow rate (US gal/min) D = bore diameter (mm) D = bore diameter (inches)

If possible mount the pump below the lowest level of fl uid in the tank. If necessary prime the pump on start-up. Ensure that inlet lines are airtight. Particular care should be taken where high speeds and/or high fl uid viscosities are involved.

As a general rule pressure at the pump inlet should not be less than 0.93 bar absolute (2" Hg depression) at normal viscosity of 23 mm2/sec (110 SSU).

SUPER QUIET, HIGH PERFORMANCE HY DRAU LIC PUMPS

A RANGE OF SINGLE AND MULTIPLE PUMPS

Triple, quad and other combinations are also available, please consult your DB Hydraulics representative for details

Pump elements are available with displacements from 6.0 to 22.9 cm3/rev (0.366 to 1.397 in3/rev) for maximum continuous operating pressures of 250 bar and peak operating pressures of 280 bar. Maximum inlet pressure is 2 bar.

Pumps can be supplied as single, or double units. Triple, quadruple and add-on units to other pumps are available in a wide variety of combinations.

Please contact your David Brown Hydraulics representative for more information on possible combinations of triple and quadruple pumps.

1PH pumps incorporate unique David Brown Hy drau lics helical gear technology to give highest per for mance with lowest noise levels within an aluminium body.

Helical gears reduce pressure ripple by smoothing out small fl ow variations associated with gear pump technology and signifi cantly reduces generated noise within the machine structure. Using appropriate shafts, bearings, and cast iron end plates within a rigid construction gives good life expectancy.

Component accuracy and pressure compensated side plates ensure that high performance is maintained.

Before dismantling ensure that the external surfaces of the pump and any work surfaces are clean.

Identify parts as they are disassembled so that they can be rebuilt in the same order, i.e. wearplate position, gear mesh etc.

Examine metal parts for signs of degredation or wear, if there are any serious signs of wear on the gears, in the housing, or in the bearings, then the complete pump should be replaced.

If all metal parts are in good order the pump may be rebuilt using new seals throughout.

1PN SERIES SERVICING DATA

Before dismantling ensure that the external surfaces of the pump and any work surfaces are clean.

Identify parts as they are disassembled so that they can be rebuilt in the same order, i.e. wearplate position, gear mesh etc.

Examine metal parts for signs of degredation or wear, if there are any serious signs of wear on the gears, in the housing, or in the bearings, then the complete pump should be replaced.

If all metal parts are in good order the pump may be rebuilt using new seals throughout.
