Gear Pumps1 to 10 cc/revCapacity

An EXTERNAL GEAR PUMP consists basically of adrive gear (rotated by an external source via a shaft)and a meshing driven gear in a housing with an inletand outlet port. Fluid is forced through the pump as itbecomes trapped between the rotating gear teeth andthe housing. Because the output per revolution isbased on the fixed volume displaced by the gears, theflow rate may be varied only by varying the gear speed.

12 Relief Valve Setting

On all pumps incorporating relief valves, pumpcode must indicate relief valve pressure settingwhich is to be indicated as follows: 01 = 100, 02 =200 etc. These digits represent desired valvesetting multiplied by 1/100. When no specific valvesetting is specified by customer relief will be set at06B thru 30B @ 2000 psi, 37B & 47B @ 1200 psiand 59B @ 750 psi.

G Customer can select from 6 standard displacements

ranging from 2.5 to 12 cc/rev with pressures to 172bar and speeds to 4000 rpm.

G Positive displacement pressure balanced gear type

pumps for use with non-corrosive liquid withlubricating properties.

G Light weight, compact and sturdy construction, isideally suited to machine tool and mobile equipmentcircuits.

G Durable die cast aluminium housing, combination

two bolt/four bolt flange mounting needle bearingsand optional internal relief valve and check valve ondischarge contribute to overall efficiency anddependability.

G Internal relief valve drain eliminates the drain port.

External relief valve drain is available in which caseoil must be returned to tank below the fluid surface.

G Square keyed shafts are standard with tang shafts

Hydraulic GearPumps12 to 32 cc/revCapacity

An EXTERNAL GEAR PUMP consists basically of adrive gear (rotated by an external source via a shaft)and a meshing driven gear in a housing with an inletand outlet port. Fluid is forced through the pump as itbecomes trapped between the rotating gear teeth andthe housing. Because the output per revolution isbased on the fixed volume displaced by the gears, theflow rate may be varied only by varying the gear speed.

103 bar

Capacity:12-32 cc/rev (see Table 1, ordering codes)

GCompact and rugged cast iron housings, designedfor extra strength, are assembled for evendistribution of pressure loads.

G Double-row ball bearing absorbs compound driving

thrust and heavy duty needle bearing assure highmechanical efficiency.

G Uni-directional rotation permits internal bleeding

thus eliminating the drain port*. Bi-directionalrotation requires external draining.

G Temperature and oil resistant double lip type seals

are standard. Viton or mechanical (face) seals areavailable at extra cost.

G Suitable for mining and underground use when fitted

with Steel Pilot Plate.

G * For installations of this type clockwise (RH) or anti-

clockwise (LH) when looking at the shaft end of thepump should be specified

pumps for use with non-corrosive liquids withlubricating properties.

G Pressure balanced wear plate gives high volumetricefficiency and prevents clearance changes due tooperating heat.

G Seal chamber pressures are low, eliminating seal

leaks and internal thrust bearing loads.

G Internal drain eliminates the need for an external

drain line.

G Optional flow divider manifold allows a pre-set

constant flow of oil at the regulated port.

G Exceptionally compact design combined with highefficiency makes the YC series ideal for hydraulicapplications where space is at a premium andweight is a critical factor.
